Hello,
I use the following row dataformat with RAW API:
[ { "Datum" :"2016-10-30T12:49:04.866Z", "Temperatur" :98.6, "Feuchte" :98.6, "Wind" :98.6 } ]
When adding a line chart as a new dashboard card (top right), I cant select a time range and see no lines.
A report from same data works (bottom right):
