This affects Matomo 3.13.0
Integer numbers like the total number of visitors are correctly shown in graphs, but are crippled by one place and shown with a thousand-separator(?) in the wrong place.
So 2014 visitors are shown as 2,01 vistors in the sparkline.
Please see the following screenshot:
Looks like the graph is not using the local number formatter 👍
so will be fixed?
It's already fixed and will be included in the next release.
