Hey Guys!

I’ve started to work with tago.io a few weeks ago and successfully managed to get the data of my soil sensor in my first dashboard

“Bodenfeuchtigkeit” is the german for water soil btw

To accomplish that i have used the card widget, so far so good, but now i want to use a chart to make the change over time visible and tried my best with the line chart widget.
I’ve selected the same device and variable like I did with the card widget, but all I get is an empty chart.

Am I doing something wrong?

I’m thankful for every hint!

Best regards,
Robert
