Strukturformel der Cetoleinsäure

Vielen Dank für die schöne und korrekte Strukturformel. Ich möchte vorschlagen, zukünftig am Ende der Kette die "CH₃"-Gruppe explizit einzuzeichnen. Dadurch wird eine solche Strukturformel auch für Nichtprofis etwas leichter verständlich. Im Europäischen Arzneibuch wird das beispielsweise genau so gehandhabt. Es stimmt, es finden sich in der Wikipedia weiterhin viele Strukturformeln mit dem von Dir gewählten Abstraktionsgrad. Eine schöne Adventszeit zu haben wünscht Dir --Jue (talk) 18:31, 13 December 2017 (UTC)

Vielen Dank für den Hinweis. Ich denke, ich werde dies in Zukunft berücksichtigen, indem ich eine zusätzliche Version mit terminalen "CH_X"-Gruppe hochlade. Ich wünsche besinnliche Weihnachten. --Hbf878 (talk) 20:28, 23 December 2017 (UTC)

New SVGs

Moved from user page to talk page. Glrx (talk) 02:15, 21 January 2019 (UTC)

Thanks for making SVGs of some chemical images.  :)

Regarding File:Methanonaphthalene-synthesis.svg, is there a reason the last two yields are 80%? They were 85% in the original. Also, can you do something about the position of the italicised "t" of tBu–OK? If you look at how it appears on en.WP, the "t" and the "B" often overlap. Thanks. EdChem (talk) 03:09, 15 January 2019 (UTC)

@EdChem: The 80% thing was a mistake, thanks for catching that; I've corrected that.

For the tBu, the overlap is caused by the thumbnail generating software on Wikimedia. For 500px thumbnail size, there is overlap, whereas for 2000px thumbnail size, the text is displayed correctly. I suspect this is because the t of tBu is in a seperate text chunk (tspan) than the Bu because the t is italic and the Bu is not. Apparently, the thumbnail generating software struggles with relative positioning of the t and Bu chunks for small thumbnail sizes.

I know for sure that changing the t to "non-italic" would resolve the positioning issue, but that would be kind of incorrect from a chemical point of view, right? For now, I inserted a dash to get some distance between t and Bu, but I'm not entirely convinced by the new output.

Another thing that would help would be converting all the text to paths (I wrote something about this on my User page), but during the last weeks I've been reluctant to do that because this does somewhat torpedo central advantages of the SVG format for text-containing images, namely editability, accessibility, translatability and file size (therefore performance). Right now, my strategy is to convert atom labels in molecules to paths (to make sure they match the chemical drawing guidelines) but preserve texts (reaction conditions, remarks...) – hoping that soon the SVG renderer will improve and the full advanages of SVG will come into effect.

What would you consider more important – smooth looks or the advantages of "raw text"?

Autopatrol given

Hello. I just wanted to let you know that I have granted autopatrol rights to your account; the reason for this is that I believe you are sufficiently trustworthy and experienced to have your contributions automatically marked as "reviewed". This has no effect on your editing, it is simply intended to make it easier for users that are monitoring Recent changes or Recent uploads to find unproductive edits amidst the productive ones like yours. In addition, the Flickr upload feature and an increased number of batch-uploads in UploadWizard, uploading of freely licensed MP3 files, overwriting files uploaded by others and an increased limit for page renames per minute are now available to you. Thank you. --Majora (talk) 00:22, 20 October 2019 (UTC)

Sorting legend in same order as the curves

Thank you for fantastic plots. It is usually much easier to identify curves in larges diagrams (with many curves) if the legend was placed to the right instead of to the left, and sorted in descending order based on the most recent value (the largest value). Then for example the EU plots would be more usable. Also, number of deaths per 1 000 000 capita would be really interesting.Tomastvivlaren (talk) 13:16, 25 March 2020 (UTC)

@Tomastvivlaren: Hi, I've implemented your suggestions for File:COVID-19-fullEU-log-relative.svg. However, as some of the lines are really close together, it's not possible to align each legend entry precisely to the end of the curve it belongs to, thus just the order is preserved.

This is the number of deaths per million; countries without deaths are omitted: File:COVID-19-EU-log-relative-deaths.svg

--Hbf878 (talk) 16:28, 25 March 2020 (UTC)

Great - I really like it. I imported it to sv:Coronavirusutbrottet_2020_i_Europa#Smittade_och_döda. Hopefully others will like it as well and keep it.Tomastvivlaren (talk) 17:57, 25 March 2020 (UTC)

Well, it didn't last very long, but I guess that's the way it goes. Glad you like it. --Hbf878 (talk) 23:42, 27 March 2020 (UTC)

I made a new attempt. Did you forget Norway Hbf878 and (iceland)? One option could be to leave out small countries with jerky result, such as Iceland. Tomastvivlaren (talk) 16:43, 28 March 2020 (UTC)

Hi @Tomastvivlaren: , the chart includes only countries that are in the EU. My reasoning was that if I include all countries of Europe, the chart would be too crowded. Thus I'd need to define some criterium to include / exclude countries, but all of these criteria are disputable:

• Should only big countries be included (→what about small countries, in some small countries the situation is more severe than in the big countries) or
• should only countries with a high absolute number of infections be included (this would bias the list of shown countries towards high population countries) or
• should only countries with a high relative number of infections be included (this would clog the upper part of the graph because all of the lower lines would be gone; also this tends to bias towards small countries).

I chose to show whole EU to avoid making a choice in this respect. If you have a good rationale of which countries to include, let me know. --Hbf878 (talk) 17:03, 28 March 2020 (UTC)

Hi @Tomastvivlaren: , I've made another chart that removed EU countries <4 million inhabitants and includes some non-EU countries: File:COVID-19-Europe-selection-relative-deaths-log.svg --Hbf878 (talk) 16:32, 2 April 2020 (UTC)

Hello @Hbf878: . Great - looking forward for an update. Inspired by you, I have made a similar plot for the counties of Sweden. Tomastvivlaren (talk) 15:16, 6 April 2020 (UTC)

log plot of EU deaths per million capita

Hello Hbf878. Thank you very much for your effort to plot and disseminate statistics about covid19.

I have read the above discussion where you and Thomas discuss the rationale for inclusion and exclusion of data traces. I wonder if it would be difficult to separate onto two adjacent graphs (Western Europe) and (Eastern Europe)? In that way we might see all the data, including the smaller countries... including Belarus if possible. Just take capital cities East or West of an arbitrary median line.

Do you know whether the statistics exist for the near middle East? All countries in the triangle Turkey, Iran, Egypt?

Thanks again for your stellar job!

Magnovvig (talk) 18:40, 6 May 2020 (UTC)

Hi @Magnovvig: ,

I will look into ways of splitting the graphs into two. I'll probably make a separate graph "European countries that are not in the EU", because all EU countries are already covered by an existing diagram. In that graph, I can then show the accumulated EU data (just the black line) for comparison. To be clear: you're interested in a logarithmic deaths per 1,000,000 inhabitants diagram, right?

I use data provided by the ECDC, which contains case and death numbers for (virtually) all countries on earth, thus also for the near east. The ECDC reports are based on the numbers published by the respective national health institues, thus potentially less accurate for this region, though.

From your request I gather that you are interested in COVID data about Belarus, therefore I've made File:COVID-19-Belarus-log.svg and File:COVID-19-Belarus.svg (updated daily), in case you need them.

Cheers, Hbf878 (talk) 12:50, 7 May 2020 (UTC)

You are a star and an angel, Hbf878!

Yes, I am interested in a logarithmic deaths per 1,000,000 inhabitants diagram.

Thanks for your remark on the source of your data, and your action on the Belarus graph.

I wonder: is your dataflow process automatic, wherein an algorithm writes the graphs once to 'your' computer, and then some sort of bot on wikimedia collects the graph files for dissemination here? Or have you automated a wikimedia computer to do it all in one shot?

Magnovvig (talk) 14:27, 7 May 2020 (UTC)

Further to my query: yes, I am "interested in a logarithmic deaths per 1,000,000 inhabitants". I see only a logarithmic "COVID cases in Belarus". Given that the population of the country is 9.5 million, would the country be a statistical outlier north of, say, Belgium on the EU log relative deaths plot?

edit: No! Not for the first time in my life, I misinterpreted the data. In fact the deaths stat roughly parallels Croatia and Poland, does it not? It is well below the EU average. This statistic is an anomaly, would you not agree?

Magnovvig (talk) 15:32, 7 May 2020 (UTC)

Hello @Magnovvig: ,

I've prepared the following diagram showing european countries that are not part of the EU: File:COVID-19-Europe-nonEU-relative-deaths-log.svg. It's intended as the complementary diagram to File:COVID-19-EU-log-relative-deaths.svg. Hope it helps.

Regarding your other question, I generate the diagrams on my local computer using Python3 and matplotlib.

Best, Hbf878 (talk) 23:55, 8 May 2020 (UTC)

Thanks for the timely and beautiful plots, Hbf878!

All this begs the question of the Americas, doesn't it? :)

At a first guess, I would have thought bash and gnuplot.

Have you mastered it with a cron job yet, or does it still need your presence at the keyboard?

Do you plan eventually to publish a letter on your valuable and brilliant work in, say, Nature or PLOS?

Cheers, Magnovvig (talk) 07:03, 9 May 2020 (UTC)

Plotting values below 1

Thanks for your remarkable job. Just a detail. Since you are plotting 3 days moving averages, the smallest feasible value is .333. Why don't you have your graphs making feasible to display these values by including values from .1 to 1 ? This would help for not so populous countries such as Israel ? --olevy (talk) 08:12, 11 July 2020 (UTC)

Hi Olevy,

I initially (when I only plotted the counts, not the increments) set the lower Y limit to 1 because 1 is the lowest plottable count. I just didn't change it when I implemented the increments. However, I'm slightly opposed to changing the lower limit drastically below 1, because I think that some people may be confused if the diagrams show below-zero values. Also, the "below 1" region tends to be quite noisy, showing every single detected case, so not showing it seemed like a good idea to me.

This is what a lower limit of 0.3 would look like. Do you think it's better?

Best, Hbf878 (talk) 15:35, 11 July 2020 (UTC)

I've implemented a small change now that at least shows the value "1" more clearly. I think it looks a bit less empty now for Israel. --Hbf878 (talk) 13:32, 13 July 2020 (UTC)

I just see now your proposed change for Israel. Thanks for the proposal. I think it is making sense. When displaying your graph, I can add a short explanation for values below 1. --olevy (talk) 9:09, 31 July 2020 (UTC)

One week moving averages

Hi, thank you for this excellent work. Could you make the french one (and the other’ones?) on a "one week" moving average , in order to take into account variations due to week-ends ( when the data are not comprehensive)? How to have the text in french in the svg file? Thanks. --Thepat (talk) 16:59, 5 October 2020 (UTC)

Hi Thepat, thanks for your input. I have been thinking about the appropriate moving window size for some time already. You're right, 7d would eliminate the periodic effect of under-reporting on weekends. However, my concerns with 7d are: I upload every 3 days, which means that the graphs are outdated by 3 days on the day before the next update (I mean that the data that is shown in the image is 3 days old in the worst case). If we have a centered moving average window of 3, the plotted incremental data will be delayed another 1 day, with a window of 7 it would be delayed 3 days. Thus with a 3d window, the plotted incremental data is up to 4 days "late", with 7d window up to 6 days. I thought that the files are more useful with a <=4 day than with a <=6 day delay, because the situation is changing more rapidly now again.

About your translation question: It is possible to implement translations in SVGs, see Switch SVG. However, this is something that I would need to program manually, because the program that I use for generating the SVG files (matplotlib) doesn't support multiple languages. I will look into it, but it will take some time.

--Hbf878 (talk) 14:58, 6 October 2020 (UTC)

@Thepat: I think I found a way for the technical aspect of translation. How would you translate -daily new cases, -daily new deaths, -last update, -source and -3-day moving average into French? Regards, Hbf878 (talk) 00:05, 7 October 2020 (UTC)

Hi Hbf878, OK. Translations into french : daily new cases = nouveaux cas quotidiens, daily new deaths = nouveaux décès quotidiens, last update = dernière mise à jour, source = source and 3-day moving average = moyenne mobile sur 3 jours. Rgds. --Thepat (talk) 06:13, 7 October 2020 (UTC)

Hello Thepat, I have implemented the translations, they will be visible with the next update (tomorrow). I had to shorten some of your translations because otherwise they wouldn't fit into the text fields of the SVG. Preview here: File:Test.svg (version 07.10.20, 15:21). --Hbf878 (talk) 15:22, 7 October 2020 (UTC)

Hi Hbf878, better to write "nouveaux cas/jour" and "nouveaux décès/jour". Rgds.--Thepat (talk) 19:06, 7 October 2020 (UTC)

Hi Thepat, do you think, without the /jour it's also understandable, like here? With the /jour included, it's also a bit too long. Or is /j a commonly used abbreviation in French, so that I could write nouveaux cas/j? --Hbf878 (talk) 19:45, 7 October 2020 (UTC)

"/j" is OK--Thepat (talk) 20:12, 7 October 2020 (UTC)

Hi Thepat, translations are online. --Hbf878 (talk) 11:07, 8 October 2020 (UTC)

Thks Hbf878, the new revision is on line in french wikipedia (hope nobody will revert it). Rgds.--Thepat (talk) 12:05, 8 October 2020 (UTC)

Hi Hbf878, thanks for the last revision with the one week moving average. The curve is smoother. Rgds. --Thepat (talk) 12:02, 14 October 2020 (UTC)

SVG Beschreibung

Hallo Hbf, du bereicherst die Wikipedias mit zahlreichen guten Grafiken. Hast du schon einmal daran gedacht, in den Dateien etwas zur Entstehung anzumerken? Damit meine ich, was ich mit deiner Datei Polyborazylene Polymer.svg oder COVID-19-Tunisia-log.svg und einigen anderen gemacht habe. Den fertigen Grafiken ist nicht mehr anzusehen, wie sie entstanden sind. Du hast a.a.O. angemerkt, dass du Strukturformeln mit ChemDraw&Inkscape&SVGO zeichnest; bei den COVID-charts ist vermutlich kein ChemDraw beteiligt, aber sonst ist es analog?
Es wäre grossartig wenn du diese Angaben einfügen würdest – es gibt ein tool mit dem das ohne Aufwand gemacht werden kann. Falls du dich dazu überwinden kannst, gebe ich dir gerne alle Anleitungen. Freundliche Grüsse und PX -- sarang♥사랑 13:17, 19 December 2020 (UTC)

Hallo @Sarang: , ich werde versuchen, das in Zukunft umzusetzen und bei den älteren Chemie-Grafiken einzufügen. Die Covid-Grafiken sind gemacht mittels einer Sequenz aus Matplotlib, einem selbstgemachten Skript auf Basis von Pythons ElementTree (für die switch-Übersetzungen), Inkscape und scour. Ich hatte jetzt erstmal nur Matplotlib erwähnt (Beispiel), die restlichen Details sind ja für andere Benutzer uninteressant, nehme ich an? Oder sollte man die ganze Sequenz so reinschreiben? Guten Rutsch wünscht Hbf878 (talk) 17:55, 31 December 2020 (UTC)

Dank deiner Auskunft weiss ich nun mehr, aus dem Code war nicht mehr zu erkennen was in zB COVID-19-Tunisia-log.svg alles stattfand; exemplarisch habe ich dort das Wichtigste davon angeführt – aber "Unknown tool", wie es vom Dateibereinigungsscript ermittelt wird, ist erstmal ausreichend. Je nachdem, wie ausführlich du den Entstehungsprozess beschreiben und kundtun willst, könntest du zB irgendwo (auf einer talkpage, einer eigenen Seite, in einer deiner Dateien) einmalig eine Erläuterung hinterlegen, vielleicht am besten in englisch, und in allen betreffenden Dateien auf diese verlinken. Das wäre dann kurz und prägnant, und falls wirklich wer will ist eine genauere Information einsehbar.
Meistens wird niemand an der Entstehungshistorie interessiert sein, und der link bleibt ungenutzt. Wenn aber jemandem diese Grafiken gefallen und Interesse entsteht auch so etwas zu zeichnen, kann die Zusatzinfo unter dem link hilfreich sein. Mit dem Risiko für dich, dass du wegen genauerer Auskünfte kontaktiert wirst (mit Risiko meine ich den möglichen Arbeitsaufwand, bezüglich COVID-19 sind Wikipediakontakte 😷 ungefährlich). Ein besseres 2021 wünscht -- sarang♥사랑 07:16, 1 January 2021 (UTC)

In deiner Datei COVID-19-World-log.svg habe ich mal realisiert was ich meinte; der Zusatztext (vorerst nur in deutsch und englisch) ist IMHO ausreichend informell ohne allzu langatmig zu sein. Der Link kann durchaus noch differenziert werden, wenn du weitere Beschreibungen erstellen willst. Hoffentlich findest du meine Vorschläge sinnvoll und akzeptabel - es ist letztlich deine Entscheidung wie du was machst. -- sarang♥사랑 08:33, 1 January 2021 (UTC)

Diagrams

Btw., where did you come to that opinion, that chart isn't a diagram, while just only exploded views are real diagrams? All Wikipedia articles have always described that there are many types of diagrams and that graphs and charts are, of course, among them. Suddenly, one or more people who deny it appeared here. However, they did not succeed in enforcing this view on Wikipedia. I'm not an expert in English dialectology, but I find it strange. Especially if the "revolutionaries" can't explain it or reflect on the contradiction. Where did a group with such a strong opinion come from, and how is it possible that no one has promoted such an opinion on the English Wikipedia for at least 12 years before now? I really do not want to be the arbiter of this dispute, but I find it unacceptable that such a contradiction be created between Wikipedia and the Commons, so that the current consistent structure of categories begins to be hastily and thoughtlessly disrupted.--ŠJů (talk) 19:54, 20 January 2021 (UTC)

Hi @ŠJů: , this question popped up when I prepared a publication some time ago, and it recently arose again when I wanted to upload a file on COVID vaccinations. I looked for a category "Diagrams about COVID-19 vaccinations" (in analogy to the COVID by country categories), but found only Category:Charts about COVID-19 vaccinations. I wondered what the difference between diagram and chart might be. After some digging around the internet I came to the conclusion that there must be some difference, for example line diagrams seem to contain information about connectivity whereas line charts show the relationship between data series. My impression was that diagrams are more explanatory whereas charts are more descriptive. That's why I wrote a message on your talk page because the term "chart" seemed to describe the content of the catefory Category:Diagrams about the COVID-19 pandemic in Taiwan more precisely than "diagram". The exploded view was merely an example for an explanatory illustration, not a comprehensive representation of what I'd consider a diagram.

Regarding your question about Wikipedia, I don't follow discussions about this topic. However, we both know that Wikipedia is not always right per se – if it were, we as authors would not be required any more. Concerning what happened 12 years ago, I have to say that I was not around then, so I don't know what kind of consensus was reached back then. Regarding the Wikipedia article about line charts which I consulted, the latest change that claims that line diagram is a synonym of line chart is not backed up by the reference that follows.

I don't know about the technical details, but what would happen if for example Category:Diagrams about the COVID-19 pandemic in Taiwan were to be renamed to "Charts about..."? To my understanding, the central rule in categorization is that more specific categories are children of less specific categories. If charts are a subtype (i.e. a child) of diagrams, then a subcategory "Charts about the COVID-19 pandemic in Taiwan" could still be categorized as a child of Category:Diagrams about the COVID-19 pandemic by country, or am I mistaken? --Hbf878 (talk) 00:30, 21 January 2021 (UTC)

In the current categorization system, "Diagrams" was the main and basic categorization tree of diagrams, while trees of specific subtypes (as charts etc.) are not so developed. I.e. all diagrams are categorized primarily as diagrams of its subject. Diagrams by subject has 62 subcategories (and hundreds of their subcategories), while Category:Charts has not its Charts by subject subcategory yet, and there are ca 3 existing subcategories of charts by subject (Political charts, Demographic charts and Phase diagrams). So, above all, it is necessary to respect the structure that exists. If we want to newly develop a similar structure at some lower level (specific subtypes of diagrams, e.g. charts), it should not break the existing system, but it should complement it. In general, however, the categorization of diagrams by topic is still fully developed at the "diagrams" level, while "Charts" are categorized in their tree rather by type than by topic/subject. I find that meaningful. If we still want to create a category "Charts about the COVID-19 pandemic in Taiwan", it should remain as a subcategory of the existing Category:Diagrams about the COVID-19 pandemic in Taiwan which should be not missing. The category Category:Charts about COVID-19 vaccinations was created by that user who refuses to respect current conventions and the current structure of categories, and fails to come to terms with the fact that charts are also a type of diagrams. Such a category name is currently an anomaly in the system. I do not consider it appropriate, necessary or beneficial to disrupt the system with such anomalies, especially if the person concerned has not sufficiently substantiated and considered the consistency of such a change. However, within this topic, both terms are almost synonymous, because the vast majority of diagrams about it are charts (and all charts are diagrams). It can be said that charts are prototypical diagrams: the main and most commonly and widely used type of diagrams. Specific subcategories are advisable rather for rare types of diagrams. In general, I do not prefer the word "diagram" over the word "chart", but above all it is necessary to build on the existing structure of categories and respect it. But overall, it is necessary to count on it that there is a certain part of people who do not have sense of system, and then sometimes we have to deal with the fact that they disturb the system, and try to somehow compensate and reduce the damage, if it cannot be prevented. --ŠJů (talk) 01:25, 21 January 2021 (UTC)

File:Major railway stations of London map.svg improvements request

Hello and thanks for creating this SVG map of London train stations. It is a good map and I have since corrected two mistakes myself. It really caught my interest because there is no other such SVG map showing the stations and termini of railways of London. But the map both needs updating and completeness. I am not a skilled map editor so 2 months ago I posted a request discussion on the WikiProject UK Railways talk page, without someone clearly stating their willingness to make these improvements. However I have now discovered that you (the original creator) are still active, therefore I am writing this request here. Are you able to improve and update this map? To cut it short, it needs:

• missing termini stations like Moorgate, as well as other missing stops in the area like City Thameslink
• updating to show the newly opened Elizabeth line track
• have borders showing the other London boroughs like Camden (at the moment it only shows the City, which you mistakenly put as 'Inner London', now fixed)

Note that also the map currently is not centred at the middle point of London. The map currently extends too much to the east and north.

I have a vision that this could become a really great and useful map if it's both updated and completed - it can even be used as a base to make further derivatives from it like one showing outside destinations or line names. Please let me know what you can do! Thanks. Manche Captain (talk) 16:02, 12 August 2022 (UTC)

Hi Manche Captain, thanks for making the corrections. Briefly on the background of the map: I made it in analogy to File:Gares_de_Paris.svg. The intention was mainly to show the overall railway layout with a host of terminus stations surrounding the city centre, forming the starting points of a number of railway lines leading away radially. It's always difficult to decide which information to include in a map. I opted for a minimalistic approach so that the overall topology is easy to grasp at first glance. I added the city of London outlines as I assumed that this part of the city was historically relevant for the decision where to build the first major railway stations. Regarding stations, I didn't want to subjectively decide which stations to include (I have no knowledge about which London stations are important), so I resorted to the official categorisation of "level A" stations. I find this consistent and easy to justify. Also, the more information is added, the more information needs to be kept up to date. For the district borders, I thought they would be distracting from the railway topology.

The Elisabeth line can be updated easily (in fact, only the stroke style needs to be changed). For the district borders, I'd need to make a new map based on OpenStreetMap data, I don't have time for that currently. Drawing borders manually is no option for me either.

If you want a universal base map that fits your requirements, you could go to openstreetmap, then save your desired section of the map as SVG (click the "share" button on the right) and use an SVG editor such as Inkscape to delete all unwanted layers and text labels until you're left with the info that you want to retain.

Best, Hbf878 (talk) 22:19, 17 August 2022 (UTC)

Hi Hbf878. I understand what you say. If you believe in a minimalist approach and "level A" stations then it is fine - although I do wish for the flexibility of expanding it into derivatives if only someone else is able to. I'm not very familiar with this stuff.

Anyway, in that case what needs to be done right now is to get the Elizabeth line appearing. This would ideally be followed by district borders, which I hope you can find the time for in the future.

I have just updated the map and centred it - as I mentioned before, the map extended too much to the north and east. Now with the new revision it is more centred on the official centre point of London which is Charing Cross. I think as a minimalist map, it is brilliant now and I have just added it to a Wikipedia page (London station group) - however I do think it is vital to have the new Elizabeth line shown, as well as the other borders of the London boroughs. --Manche Captain (talk) 20:38, 3 September 2022 (UTC)

Update request for File:Public transport map of Athens.png

Hello Hbf878,

Can you update File:Public transport map of Athens.png by coloring the section between the Nikaia and Dimotiko Theatro stations of Line 3 in dark blue?

This section opened to service on 10 October 2022.

Unfortunately, the original uploader User:Chumwa has not been active since 8 February 2021.

(He has created great quality maps just like you, but many of his maps and other files have not been updated since then.

If you have the time and interest, can you check his maps for updates?)

Yours sincerely, 31.200.21.49 17:58, 12 October 2022 (UTC)

Hi, the linked PNG is rendered from some vector source file. Only Chumwa has that source file, so I can't make the update in the source. As a suboptimal workaround, I can tweak the png, which is what I just did. By the way, does Athens really have 2 stations named "Tavros"? How confusing.. --Hbf878 (talk) 22:23, 12 October 2022 (UTC)

Thank you very much for the update! Thank you for the explanation. Yes, strange and illogical as it is, Athens has indeed two different stations that are named Tavros. One is on Line 1 of Athens Metro and the other one is on the suburban line. It does not make sense, since they are not interchange stations with each other and are not even very close to each other. 31.200.21.49 05:24, 13 October 2022 (UTC)

Erstellung der Strukturformeln

Hi Hbf. Ich liebe wie du deine Strukturformeln zeichnest. Sie sind visuell sehr ansprechend, finde ich. Ich bin bei recherchen zu Produkten, die in meinem chemischen Betrieb hergestellt werden, auf deine Struktur von 2,6-Di-tert-butylphenol gestossen. Zwar beschreibst du deine drawing settings, aber wie genau in welchen Programmen und in welcher Abfolge du diese SVGs erstellst ist mir unklar. Könntest du mir beschreiben wie genau das geht? LG User327327 (talk) 10:35, 11 February 2023 (UTC)

Hallo @User327327:

die Strukturformeln hatte ich mit dem Programm ChemDraw gezeichnet. Dort kann man viele verschiedene grafische Parameter einstellen -- die von mir verwendeten Werte habe ich bei den drawing settings angegeben. ChemDraw bietet direkt die Möglichkeit, die Strukturformeln als SVG zu exportieren, im Grunde sind die SVG-Dateien damit schon fertig und können für viele Zwecke verwendet werden.

Wikipedia hat allerdings einige Besonderheiten was die Darstellung von SVG-Dateien angeht. Damit die SVG-Dateien auf Wikipedia so aussehen wie ich es mir vorstelle, hatte ich dann die von ChemDraw exportierte SVG-Datei mit Inkscape geöffnet, alles markiert (Strg+A) und zu Pfaden konvertiert (Strg+Shift+C), dadurch sieht die Schrift besser aus. Für eine Verwendung außerhalb von Wikipedia ist dieser Schritt aber nicht unbedingt nötig.

Außerdem habe ich in Inkscape einen durchsichtigen Rand um das Molekül hinzugefügt (das geht im Seite-einrichten-Menü Strg+Shift+D). Die alte Chemdraw-Version, die ich damals benutzt hatte (ich glaube es war Version 15), hat manchmal auch grafische Artefakte in der SVG-Datei eingefügt, diese habe ich auch mit Inkscape manuell entfernt. Die neuen Versionen von ChemDraw haben solche Probleme nicht mehr, soweit ich weiß. Dann habe ich die Datei als "optimiertes SVG" gespeichert (Strg+Shift+S).

Im Grunde braucht man also nur ChemDraw und die o.g. Einstellungen und dann kann man die Strukturformeln direkt erstellen.

Tipps zum Erstellen von Karten

Hallo Hbf!
Ich hab diese hübsche Karte von dir entdeckt und das hat mich motiviert mir das ganze auch mal anzuschauen. Allerdings habe ich nicht wirklich viel dazu gefunden. (Hab mir u.A. Maperitive mal angeschaut, allerdings ist die Verwendung von einigen Kartenansichten aufgrund der veralteten Software nicht möglich, was ich sehr schade finde!)

Daher wollte ich dich fragen, ob du Tipps für Newcomer hast? Sehr schön wären z.B. Software Vorschläge (ggf. mit entsprechenden Einstellungen) oder thematisch passende Tutorials/Hilfeseiten!

Danke dir schon mal im Vorraus! Berdi2 (talk) 20:38, 10 January 2024 (UTC)

Hallo Berdi2, vielen Dank für dein Interesse. Die von dir verlinkte Karte ist tatsächlich mit Maperitive erstellt - alternativ habe ich auch mal eine Karte basierend auf der openstreetmap.org Kartenansicht erstellt und auch QGIS mal ausprobiert (für sehr große Kartenausschnitte). Die Karte von Maperitive/openstreetmap.org habe ich dann jeweils mit Inkscape bearbeitet (Adobe Illustrator ginge auch, kostet aber Geld). Beide Optionen (maperitive, openstreetmap.org) sind leider recht zeitintensiv - vor Allem das Bearbeiten mit Inkscape hinterher.

Was konkret meinst du bzgl Maperitive mit Verwendung von einigen Kartenansichten nicht möglich? Bisher hat Maperitive eigentlich all meine Wünsche erfüllen können. Gibt es einen Punkt wo es hakt?

LG Hbf878 (talk) 09:23, 11 January 2024 (UTC)

Erst mal danke für die vielen Tipps!

Ich vermute stark, dass du die Transport Ansicht von OSM nutzt. Um die in Maperitive zu verwenden brauche ich offenbar einen API Key, der ist auch an sich kein Problem (kostenlos einen Account auf thunderforest erstellen), aber Maperitive hat keine Funktion diesen Key irgendwo einzufügen (vgl. Diskussion in der Google Group).

Daher hatte ich gehofft/vermutet, dass du eine Alternative nutzt, die diese Funktion besitzt.

Inkscape hatte ich tatsächlich auch schon entdeckt und Maperitive Regeln hab ich auch schon ganz gut verstanden.

Also was mich da am meisten interessieren würde, ist welche Karten du verwendest und falls es Transport ist, wie das bei dir funktioniert.

Danke :) Berdi2 (talk) 09:44, 11 January 2024 (UTC)

Hallo Berdi2, ich lade die openstreetmap-Rohdaten mit der Overpass-API (spezielle Abfrage, damit keine unnötigen features heruntergeladen werden) auf meinen PC herunter und lade diese dann in Maperitive mit load-source. Ich benutze also nicht die Map-Tiles, die beim Öffnen von Maperitive standardmäßig zu sehen sind, und auch nicht die transport map (die kannte ich noch gar nicht, sieht aber auch gut aus). Dann habe ich ein Maperitive-Ruleset, in dem definiert ist, welche OSM-Features wie dargestellt werden sollen (zB Wald grün, Bahnstrecke grau, Autobahn gelb usw). Entsprechend dieser Regeln erstellt dann Maperitive die Roh-Karte. Das Relief (hillshading) erstelle ich auch mit Maperitive (igor-hillshading), die Höhendaten dazu kommen gratis von der NASA (sind aber nervig herunterzuladen, für Deutschland kann ich sie dir auch zukommen lassen). Von Maperitive exportiere ich dann die Karte, entweder als PNG (einfach, das Relief ist direkt integriert) oder SVG (das mit dem Relief ist dann ziemlich kompliziert, dafür kann man nachträglich noch die Farben korrigieren usw, und Änderungen in der Realität leichter einpflegen). Die exportierte Karte bearbeite ich dann in Inkscape, indem ich die Bahnstrecke und Bahnhöfe in Rot draufzeichne und die Beschriftungstexte draufschreibe. Dann hab ich zuletzt begonnen, die finalen Karten als SVG hier hochzuladen, da PNG-Dateien nachträglich von anderen Leuten nahezu unmöglich zu bearbeiten sind.

Die andere Option - Export eines Kartenausschnitts von openstreetmap.org direkt als SVG (rechts beim "teilen"-Button)- ist in mancher Hinsicht leichter, da man sofort eine schicke Karte mit Ortsnamen-Beschriftungen usw bekommt, allerdings sind die exportierten Dateien oft riesig groß (zu groß für Inkscape), sodass man erstmal mit einem Texteditor (Notepad++ mit Hilfe regulärer Ausdrücke) oder mit Illustrator die unnötigen features entfernen muss. Genaueres ist in dieser Anleitung beschrieben, den Export von OSM als PDF hab ich jedoch noch nie ausprobiert. Und mit dieser Variante hat man kein Relief.

LG Hbf878 (talk) 12:34, 11 January 2024 (UTC)

PS: Bei Interesse kann ich dir die Overpass-Abfrage und Maperitive-Rulesets geben, die habe ich aber auf einem PC den ich nicht regelmäßig benutze, könnte also etwas dauern.

Hallo Hbf!

Danke für die ausführliche Erklärung, das hat mir das ganze ein ganzes Stück näher gebracht.

Legende und Position innerhalb Deutschland fügst du dann auch in Inkscape ein, oder? Gibt es da Vorlagen, die man verwenden kann oder kann ich die einfach z.B. aus einem deiner Karten kopieren und für meine anpassen?

Ich bin ein wenig verwirrt von deiner Aussage über das Relief, zumindest mit den Default Regeln sieht das sehr gut aus im SVG.

Es wäre sehr nett, wenn du mir das Maperitive-Ruleset schicken kannst! Man muss das Rad ja nicht neu erfinden ;)

P.S.: Die Overpass Daten kann man übrigens auch ganz easy für einen ausgewählten Bereich direkt in Maperitive herunterladen. Berdi2 (talk) 19:43, 11 January 2024 (UTC)

Hallo Berdi2, die Maperitive Rules habe ich hier abgelegt. Je nachdem, ob man zB abgebaute Bahnstrecken, U-Bahnstrecken, S-Bahnstrecken o.ä. zeigen oder weglassen möchte, müssen die Regeln entsprechend angepasst werden. Das schöne an SVG ist, dass wenn einem hinterher auffällt, dass man diese und jene Linie doch etwas dicker oder dünner haben möchte, dann kann man das im Nachhinein noch ändern, mit PNG muss man nochmal ziemlich von vorne anfangen und sich insbes. die Zoomstufe beim Exportieren gut merken.

Genau, die Deutschlandkarte und Legende mache ich mit Inkscape. Auch die Bahnstrecke, um die es geht, zeichne ich mit Inkscape (Bezier-Tool), für die Stationen nehme ich Kreis-Symbole. Die Deutschlandkarte, Legende usw kannst du dir gerne aus einer meiner Karten kopieren und anpassen.

Was das Relief betrifft, das ist by default eine transparente Raster-Ebene (PNG), die in der SVG eingebettet ist, es wird also möglicherweise unscharf bei starker Vergrößerung. Ich hatte stattdessen zB hier das von Maperitive generierte Relief-PNG in eine Vektorgrafik umgewandelt. Ist wohl Geschmackssache ob das dann besser aussieht.

Für Anfragen an Overpass gibt es ein Limit von 2GB (könnte mittlerweile mehr sein); bei großen Kartenausschnitten wird dieses Limit mit der eingebauten Download-Funktion (die lädt einfach alle Features im gegebenen Bereich) überschritten, dann muss man spezifisch die gewünschten Features auswählen damit die Datei klein genug bleibt. LG Hbf878 (talk) 19:03, 15 January 2024 (UTC)

Hallo Hbf,

vielen Dank! Ich versuche mich mal an meiner ersten Karte und melde mich dann eventuell noch einmal.

Vielen Dank, dass du deine Zeit dafür eingesetzt hast, mir den Einstieg zu ermöglichen :)

P.S.: Relief werde ich wohl erstmal in PNG lassen, mal schauen. Berdi2 (talk) 20:31, 15 January 2024 (UTC)

Ich hab die Karte jetzt hochgeladen. Wenn du Bock hast, kannst du gerne drüber schauen, ob dir irgendwas auffällt, aber du hast natürlich schon sehr viel für mich getan und ich erwarte das in keiner Weise von dir :)

Außerdem hab ich dein Ruleset unter Contributions verlinkt. Falls du das nicht willst, entferne ich das natürlich unverzüglich wieder.

Nochmal vielen, vielen Dank für deine Hilfe. Bisher macht mir das Erstellen Spaß und ich glaube, dass ich die betreffenden Artikel wirklich verbessern kann. Berdi2 (talk) 22:00, 17 January 2024 (UTC)

Freut mich, dass ich dir helfen konnte. Ich hab gesehen, dass du auch schon in der Kartenwerkstatt aktiv bist, also steht einer erfolgreichen Kartenzeichnerkarriere wohl nichts mehr im Wege ;) --Hbf878 (talk) 21:07, 31 January 2024 (UTC)

Deine hervorragenden Eisenbahn-Karten

Erstmal ein großes Danke für deine bisherigen hervorragenden Karten zu Bahnstrecken. Da ich gerade an einem Artikel zur neuen Brennerbahn (Innsbruck-Verona via Brenner-Basistunnel) arbeite, wäre dafür langfristig eine Karte im Stil von File:Brenner-Nordzulauf Karte.svg oder File:ABS+NBS Karlsruhe–Basel Karte.svg sehr wünschenswert.
