Strukturformel der Cetoleinsäure[edit]

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 "CHX"-Gruppe hochlade. Ich wünsche besinnliche Weihnachten. --Hbf878 (talk) 20:28, 23 December 2017 (UTC)


Hello, as you know I reported the file as File:Nitrite-group.svg. Usually this version is used. Good wiki!--Grasso Luigi (talk) 19:40, 17 January 2019 (UTC)

New SVGs[edit]

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"?

Hallo Hbf878, in deiner neuen Version sind die terminalen CH3-Gruppen uneinheitlich dargestellt. Magst du dies anpassen? --Leyo 14:07, 18 October 2019 (UTC)

Gut aufgepasst, ist korrigiert für File:Fluazifop-P-butyl.svg und File:Fluazifop-butyl.svg. --Hbf878 (talk) 20:58, 18 October 2019 (UTC)
Danke! --Leyo 22:46, 18 October 2019 (UTC)

Autopatrol given[edit]

Commons Autopatrolled.svg

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 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[edit]

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

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)
