[SOLVED] Charts unique name problems

Dear Community!

I have started using charts, but now I have some problems with it. I have one chart which works fine (my phone’s battery level on it). However if I want to add another chart which is a Group with more battery levels in this group I get this error:

2018-03-31 19:56:06.669 [WARN ] [thome.ui.internal.chart.ChartServlet] - Illegal argument in chart: Series name >Battery Level< has already been used. Use unique names for each series!!!

Any ideas?


Reading the Documents, you could find:

When charting a group of item, make sure that every label is unique. If the label contains spaces, the first word of the label must be unique. Identical labels result in an empty chart.

Thank you for your help!!! I read this before, but somehow I always thought that item names must be unique, and I haven’t noticed that the labels are the same…

Thanks again!
