Hi
I have a plot , when i hover over the plot line, it displays the value. At the same time i would like to also display the temperture, which is also part of the dataset but not displayed on the plot.
How do i edit the tooltip, so that additional information can be displayed on the tooltip ?

You need to attach it to the DataTipTemplate property. Check DataTipTemplate as well.

Hi
Ok i can get it working if my plot has only one data set e.g.
s=plot(t,ug)
But i gett the following error message, when a plot has multiple plots
s=plot(t,ug,ref_data_timestamp,ref_data_sensordata)
Intermediate dot '.' indexing produced a comma-separated list with 2 values, but it must produce a single value when followed by subsequent indexing
operations.
Error in n02 (line 141)
s.DataTipTemplate.DataTipRows(end+1) = row;
