Thanks for the report!

I could reproduce also. the problem comes from the fact that in German numbers are: 0,8s and this results in the bug (in english they are displayed as 0.8s)

That one already works for me on the current demo.

Might be fixed in #6435. Please note even if it seems to be fixed on the current demo it could be still broken depending on which locale Piwik uses to track and archive data.

I just tried to reproduce on demo and it still shows the data in full seconds instead of floats when using German language... I'll have a quick look

I have a fix for this that I will merge as soon as the tests pass. It will now output actual float values but it will use a dot instead of a comma to separate the decimal part which is wrong. I cannot really fix this currently as we need a lib to format numbers in JavaScript depending on the users language/country etc. We should fix this in #6620 and pick a lib there. It shows once more how important this issue is.

I cannot format the number in PHP (I tried it) as it will be converted to float in JavaScript again: parseFloat('0,34') results in 0 as it is not a valid float.
