I found some really helpful advice in How to plot horizontal line in Timeseries in Grafana and now I would like to apply this to my Timeseries Chart with multiple thresholds.
My data source provides thresholds as 2d array:
0, 1, 2, 3
100, 200, 300, 400
101, 201, 301, 401
the first line is the header ;)
An Example configuration looks like:

and the transformations:
As you can see, if I select "Last" in the Transformation, I get one threshold-line each. Here 101 and 201. But if I select "All unique Values", I get no threshold line at all.
I expected to get in total 8 threshold lines (if I select "All unique Values" for each field). How can I archive that? Is there a bug or missunderstanding here?
