SVG Chart

Mark and copy the following text. Paste it into a plain text file. The text file should have an svg extension, for example mychart.svg.

You can check the result with Toolforge tool SVGCheck (upload file temporarily), in W3Schools Tryit Editor (insert source code) or in Commons with File:Test.svg (upload as new file revision).

Template documentation[ view · edit · history · purge ]
This documentation is transcluded from Template:SVG Chart/doc.
Tracked in Phabricator
Task T36947

The SVG font-rendering is still very buggy. A font-size of 2 px or lower is completely useless. As a workaround try doubling or tripling GraphStretchHeight and GraphStretchWidth, and reducing GraphWidth by the same amount. You can add stroke-width="1" (adjust as needed) to make the lines in the legend correct.

This template generates SVG code for line charts.

The special feature is that the data is retained in its original format and can be easily supplemented or changed later. In particular, a clear structure is produced, which can easily be modified with any text editor.

This template categorizes to Created with Wikimedia SVG Chart.

Quick start[edit]

Copy sample template: 
{{SVG Chart
| XAxisText    = Year
| YAxisText    = Index
| LegendType   = none  

| XMin         = 1990
| XMax         = 2015
| YMin         = 5
| YMax         = 20
| Graph1Values =       
     1990 6.16
     2000 10.72
     2005 11.15
     2012 17.29
}}
Copy the resulting preview text into a text file chart.svg and open this file in your browser or SVG viewer. You get a result like these:

Usage[edit]

  1. Create the template {{SVG Chart}} somewhere. This means: put for instance the text in the light gray box above, which starts with {{SVG Chart on some existing page, for instance, your own user page here on Wikimedia Commons (not on Wikipedia, where it will not have any effect).
  2. Adjust the numbers and put in your own data and descriptions of the axes. Note that if you put any text in your graph, you automatically restrict its usage to a single language version of Wikipedia; consider whether descriptions of the axes are really needed.
  3. Press the "Preview" button. You now see a page with instructions followed by the source code of an SVG file on a light gray background. The instructions at the top match the next few steps in this list here.
  4. Paste (with mouse) and copy (<Ctrl>+<C>) the text in the light gray box.
  5. Create an empty SVG file e.g. mychart.svg on your computer.
  6. Open that file with a plain text editor, e.g. Notepad.
  7. Paste (<Ctrl>+<V>) the copied data into the text file. Save that file (<Ctrl>+<S>).
  8. Check the file by drag and drop on your browser, with Jarry1250's SVG Check or File:Test.svg. If you did not change the data in step 2, you will see a red and a blue W.
  9. If the check is successfully, store your file with Commons:Upload.
  10. After uploading, put the source code (the text that starts with {{SVG Chart) on the Talk page of the newly created Commons file (go to the file, and click on the "Discussion" tab at the top of the page) so that others can easily update your graph in the future.
