@Purodha: Are you going to mentor a GCI student to fix this task? If yes, please explicitly say so and thanks a lot!

I will mentor this in #GCI2015

Would mentor this for Google-Code-in-2017.

Imported as: https://codein.withgoogle.com/dashboard/tasks/6587968972128256/.

@D3r1ck01 It might be reasonable to have a bit more informative description for the task: What does the student need to change and how? Is there any information material they can use to find that out? Where do they get help or documentation on making things translateable? :)

In this screenshot taking in Farsi (fa) language, we see that in the following placed the numerals are not localised:

• The numbers on Y-axis (should use mw.language.convertNumber from MediaWiki)
• The days on X-axis (should likely use a proper date formatting from MediaWiki
• The data on the tooltip (as above)
• The number on the toolip

Fixing these requires reading the Chart.js api http://www.chartjs.org/ to understand how those places can be customized.

Thanks for the info @Nikerabbit! :)

I don't understand how to format the date on the X-axis. If I have a variable that holds the date in the format "2001-1-1", how would I go about converting this into the wanted format?

The current format is 2001-01-01 (this is also what the ISO standard says) and not 2001-1-1.

You can use moment.js to convert: moment( variable ).format('L'); // 13.12.2017

Change 398174 had a related patch set uploaded (by Ryan10145; owner: Ryan10145):
[mediawiki/extensions/ContentTranslation@master] Added Localization for CX Translation Trend Graph

Is there any way for me to get any more information about which dates in particular are causing an error with moment.js? I have tried setting up the extension on my own computer in order to see the problems for myself and try to fix them, but I have been having technical difficulties.

@Nikerabbit I might be wrong, but can you double-check for the proper font size and also the font contrast/resolution (on the tooltip too)? Looks rather small (fawiki -wmf.15, Chrome, 100% scale).

Even though it is small, it looks legible to me. I believe @Pginer-WMF or @Volker_E would know better from design and accessibility point of view whether we should create a new task to improve size and/or contrast.

@Nikerabbit The graph legend is indeed to small. From a readability perspective we should at least go for 12pt (or it's screen equivalent) if not higher. Compare this article (and its graphs).
