T90104 created a visualization of translation trends. Now the graph can have localizable numbers and labels.
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 tooltip
Fixing these requires reading the Chart.js api http://www.chartjs.org/ to understand how those places can be customized.
