I am using Simulink Data Inspector for visualization of project log data. One of my goals is to allow the user to save their active signal selection to be retrieved at a later point or to be re-used for another log. I am struggling a bit with the options on the CLI that are available for Simulink Data Inspector: I don't see a possibility to retrieve the plot handle where a certain signal is plotted.
One of my tries involved iterating all the signals of a run:
run_IDs = Simulink.sdi.getAllRunIDs
run_IDs =
2×1 int32 column vector
52435
54813
run1 = Simulink.sdi.getRun(run_IDs(1));
sig_IDs = run1.getAllSignalIDs;
sig = run1.getSignal(sig_IDs(1))
sig =
Signal with properties:
ID: 52446
RunID: 52435

LineDashed: '-'
LineWidth: 1
InterpMethod: 'linear'
AbsTol: 0
RelTol: 0

The properties one gets for a signal type include if it's currently visible (=Checked) or not. However, there is no way to get the current plot where it is active, i.e. if it's the signal in the plot to the bottom right.

Another option that I could think of is to retrieve the axis handles of the individual plots in the Signal Inspector, but I didn't find a way yet how to achieve that...
