Evolution graph in acquisitions overview not showing data

[tsteur]

See below screenshot on latest 4.X beta where it shows no data and metric names contain a %20.

The metrics to plot looks like this:

Once I click on one of the sparklines, it does show data and also shows the metric names correctly.

I can't reproduce it on the demo. Not sure if there was maybe any change around the saved datatable parameters or so.

I'm able to reproduce that locally and on the demo as well. We run a encodeURIComponent on all rows before they are stored as data table params (See https://github.com/matomo-org/matomo/blob/5.x-dev/plugins/CoreVisualizations/javascripts/seriesPicker.js#L108). Guess that maybe isn't reverted before it's used.
Not sure if simply removing that encodeURIComponent might cause other implications.

Related to or a duplicate of #20635.

Isn't this a regression maybe? I'm pretty sure this used to work

[sgiehl]

Yes. This might be a regression of the migration to vue.js

While checking this one again it turned out, that there actually also is another i18n related issue around evolution charts. If I e.g. configure that chart to show "Search Engines" and "Websites" and then change my language to German, the chart won't show any data was well. As for German there are no records "Search Engines" or "Websites". They are localized to "Suchmaschinen" and "Webseiten". So we might also need to think about storing the internal name and only showing the translation or something similar.
