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 馃憤
so will be fixed?
It's already fixed and will be included in the next release.
Thanks for fixing this, is the fix applying to the visitor section only but also to other sections like Ecommerce?
We are experiencing the same problems in the visitor overview as described in this issue when using German as language setting in Matomo (I'm coming from https://github.com/matomo-org/matomo/issues/15262), when using English everything looks to be ok.
But we also experiencing some kind of rounding error in the Ecommerce overview section. The numbers are formatted correctly there, but when using German the conversion rate is shown as 0% and when using English it's shown as 0,5% (which would be the correct number).
Could this be related?
@beamylake Could you please try upgrade to the latest beta? https://matomo.org/faq/how-to-update/faq_159/
and confirm if you still experience any issue?
We're on it, I'll get back to you as we got the results.
Thanks for working on these issues over the holidays!
It works!
With the latest beta (as by Friday, Jan 3rd) the visitor numbers are now in correct format when using German as display language.
Thanks!
Thank you team! For people who can鈥檛 go on production with a beta version I suggest writing a theme plugin reverting the modification temporarily https://github.com/matomo-org/matomo/issues/15356#issuecomment-571969811
