Upgraded Chart.js to version 4.4.2 #3233

harmitgoswami · 2024-05-17T13:48:46Z

Upgraded Chart.js dependency to latest version (4.4.2). Previously, Chart.js was included via a Chart.bundle.js static file. Support for this method has ended, so the dependency was included via a CDN. Changed all instances of deprecated functions to the new equivalents according to the migration guide.

We try to avoid loading static files from external sources. Please instead include the files in the repo.

+    <script language="javascript" type="text/javascript" src="{{ static('js/lib/chartjs-adapter-moment.min.js') }}"></script>


This will load all these libs on most of the views, even when they aren't needed.

We should load them, like other static files, through Django pipeline in settings, and only in the views where Chart.js was previously used.

Also, seems like pontoon/base/static/js/lib/chart.umd.js.map is not used?

You're right, I was getting a console error when I didn't include this file through base.html, but now that I've shifted over to local imports it seems this file isn't necessary.

mathjazz

The libraries are now loaded as expected. Nice work!

Please see my comment inline for the Profile chart.

I've noticed that the charts on http://localhost:8000/insights/ don't load.

Also, the Age of unreviewed suggestions and the Time to review pretranslations charts on http://localhost:8000/sl/insights/ shouldn't have legends.

+                  maxTicksLimit: 3,
+                  precision: 2,
+                  callback: (value) => nf.format(value),


Why the change in the precision and the callback settings?

There are a few things that don't work as expected in the new Profile chart:

The curve doesn't have a background.

The Y scale data is off.

The tooltip: items overlap, the data format is off and there is no border.

The chart is cut-off at the top.

Can we keep the line curved?

mathjazz

I haven't looked at the code yet, but the changes look good. Nice work!

I noticed a few minor things, which should still be changed:

On the X scales, there should be no day number (e.g. "Jun" instead of "Jun 1").
We don't use a thousands separator on the Y scale ATM. I think it's a good idea to use it, but it should be , rather than . (same as in the tooltip).
Borders in bullet points in the tooltips don't look the same as in production - they have a 3Dish look and the first one is bigger than the rest.

Thank you! It seems that both the day number and thousands separator styling issues are dependent on browser/location configuration (i.e. the thousands separator is indeed , instead of . and day numbers already appear in production for Firefox v126.0 en-US).

True, but I believe the situation is worse than on prod ATM, where e.g. for me all charts show months as "May" rather than "May 1", which is the case in some charts now. E.g. the chart on the /profile page shows months rightfully as "May", whereas the Time to review suggestions chart on /sl/insights shows months as "May 1".

Also, it seems like charts on the /insights page are broken again.

+                  tooltipFormat: 'MMM YYYY',


This (and other instances of the same value) should remain MMMM YYYY, which will show the full month name in the tooltip, where we have enough space.

harmitgoswami · 2024-05-28T20:02:22Z

The decision to switch from Moment.js over to Date-fns.js was mainly in hopes that the date display bug for the x-axis on charts will be resolved. The documentation for Moment.js states that no further features will be added, so it's possible that the visual consistency between that and Chart.js got lost at some point.

Very well done!

All charts work as expected.

Left some comments inline, mostly just to improve the code maintainability.

You can drop the body braces and the word "return":

Suggested change

labelColor: (context) => {

return Pontoon.insights.setLabelColor(context);

},

labelColor: (context) =>

Pontoon.insights.setLabelColor(context),

},

The same applies for all other calls of this function.
