How can I programmatically clear subplots in Simulation Data Inspector without clearing all runs out of SDI?

I am looking for a command similar to cla but for SDI. In the GUI, I can click a button labeled "Clear Subplot" and then "Clear all Subplots" but I cannot find how to invoke this same behavior in a script. I am trying to automate the plotting of many data runs, and it takes a long time to reload the runs into SDI from the .mat file if I use Simulink.sdi.clear just to clear the subplots!

This is how I do it:

function clearSDISignals
% Clear all signals from SDI canvas

Simulink.sdi.close; % SDI window must be closed, otherwise canvas is redrawn, which is slow
runIDs = Simulink.sdi.getAllRunIDs;
for runID = runIDs'
    run = Simulink.sdi.getRun(runID);
    for signalIdx=1:run.SignalCount
        if run.getSignalByIndex(signalIdx).Checked
            run.getSignalByIndex(signalIdx).Checked = false;
        end
    end
end
Simulink.sdi.view;

If your goal is to plot different runs and capture snapshots, the Simulink.sdi.CustomSnapshot class might be useful. This class provides the clearSignals method to clear plotted signals from all subplots in the CustomSnapshot object.

I've tried this and it only works if the current axes have focus. Otherwise, i'm unable to change status of 'Checked' field programatically. Does anyone else experiences the same problem? Is there any way to grab handle to SDI axes programatically?

Starting R2019b, you can use

Simulink.sdi.clearAllSubPlots

to clear all subplots without removing any runs from SDI.
