Wikipedia talk:How to create charts for Wikipedia articles

message: This page is useful. Maybe also worth mentioning that if the graph is a relatively simple bar graph, it can be created by EasyTimeline, which is fun, although the learning curve is a bit steep. (The easiest way to create a new one is to adapt an existing one.) pfctdayelise (translate?) 14:23, 15 November 2006 (UTC)

message: For economic data in particular, the graphs need to be updated periodically, eg GDP, DJIA historical plots.  I see some graphs include a data table, but most don't, and I don't see details on instructions to produce update.  Can more information be provided on this with recommendations?  I think that the data plus the GNUplot commands are the two key requirements. Mulp (talk) 20:08, 11 August 2009 (UTC)

replies: text: You can use OpenOffice to create these sorts of charts. However, SVG is the preferred image format, and OOo's SVG output isn't always correct. SharkD (talk) 03:19, 4 November 2009 (UTC)

message: I'm trying to create graphs in Gnuplot and then do post-processing for them in Inkscape. I export the SVG from Gnuplot as in the article and the result looks right when opened in Firefox, but when I open the file in Inkscape I don't see the graph. The graph is there; if go you into the XML editor in Inscape you can select it and then manually set the stroke color which will make it appear. Apparently, Gnuplot uses "stroke:currentColor;" to set the color of the curve and Inkscape only recognizes color names, so if you change the SVG to "stroke:black;" instead then Inkscape will be able to read the file properly and the cirve will appear when you open it. I've tried playing with the linetype and linecolor settings in Gnuplot but it doesn't seem to help. As I said, there is a workaround but it's a bit of a kludge. Is there something I'm doing wrong here or is it Gnuplot or Inkscape or both not working properly?--RDBury (talk) 05:15, 5 September 2009 (UTC)

message: *Here's a thread describing Gnumeric, a free spreadsheet software that is integrated with GNUplot (meaning you can create charts directly in GNUplot).
*Here's a thread I personally started discussing the woes of getting SVG output from OpenOffice into Inkscape.
*Here's a wiki page documenting users' experiences with SVG in OpenOffice.
*Here's a blog article regarding one user's efforts at importing/exporting between Inkscape and OpenOffice.
*Here's a third-party tool that can be used to import SVG images into OpenOffice. Unfortunately there's no corresponding export tool.

That is an article on record charts, so obviously wrong.
I presume it is supposed to point somewhere else.

thread_title:  Choosing colors for charts 

message: I came to this page to learn how to create and include a simple graph on a WP article. What I've understood is that I should enter the data in SVG format.  What I'm unclear of are the exact steps after that.
# Create SVG file.  Got it.
# Upload the SVG file... to where?  How?
# Edit this article to include my graph... how? What exactly do I enter in the article?
If the instructions could be updated to answer these questions, that would be very helpful. Thanks! --В²C ☎ 19:37, 2 May 2019 (UTC)
thread_title:  More detailed instructions on uploading, please 

message: This is completely ridiculous. Don't tell me to go to code crap in a terminal just to make a graph, or if you do, lay out very very clear, tiny step-by-tiny step, instructions on how to do it. Don't just say 'go to gnuplot and run this data plot'. This is completely incomprehensible and exhausting to me, who is familiar with computers and coding, imagine how someone unfamiliar with technology would find it. And Wikipedia says it wants to make it easier to edit and take part. Why can't I just use a LibreOffice graph?  — Preceding unsigned comment added by 37.164.38.114 (talk) 15:20, 1 October 2019 (UTC)

thread_title: interactive graphs on wikipedia?

message: I was wondering how people here feel about the graph extension. While it produces fairly nice graphs and charts and must have required a fair amount of work to code, it completely ignores Guideline #1 from the list here, as it does not produce SVG outputs. There is an alternative, SVG Chart on Commons, but that does not seem to be maintained anymore. I was just wondering if this is an issue that has already been discussed somewhere, and if anything can be done to improve matters. KarlFrei (talk) 07:16, 7 February 2020 (UTC)
replies: text: I suppose my question boils down to: does the text "Use SVG whenever possible" represent Wikipedia consensus / official policy, or is this just somebody's opinion? The line was put in the article in 2006, but as I said, is completely ignored in some areas of Wikipedia. KarlFrei (talk) 07:40, 7 February 2020 (UTC)

message: Could we recommend uploading source code? So sad that there are so many great diagrams I can't modify or understand how they were created.
The question is where should you put the source code? Some put it in the summary, some in the description, some in the talk page.
We need one place where you can upload source code files.--Volker Weißmann (talk) 17:47, 22 December 2021 (UTC)
