How to put a property group in a related curve with the Expansion curve text label

Hello

I'm working on a graph which trace a WaveFormChannel named 'Test '. Given that I enabled the expansion of the curve, the graph shows all channels named "Test" in the DataPortal. Now, I want to put the value of the property of the "MyGroupProperty" group in the legend, so whenever I add a new group, automatically add the new "Test" signal and show "MyGroupProperty" in the legend.

So far, I tried to use the curve text in the option of the label, with something like this

@GroupPropGet (GroupNumber, "MyGroupProperty") @, but I have to give the value of GroupNumber, and then it shows the same value for all signals. So if I add a new group to the dataportal with a Test string, the legend shows the label of the new signal, but the MyGroupProperty remains the same for all labels

Thanks in advance for your help

Hi dslemusp,

You can use the global 'CGI' variable in a tiara expression to provide the current Index of the traced (even in expansion mode) group.  I've prepared an example that illustrates this and attached it below.
