MATLAB: Hold plot toggle using app designer

app designer

I am using the app designer to create a UI with a graph (app.Graph), a hold switch (app.HoldGraphSwitch) and a calculate button (app.CalculateButton).
I want it so when the hold switch is set to 'on', then the graph holds the previous plots on the graph but if set to 'off, then the graph clears previous plots.
I have tried the following but does not clear the graph:
function CalculateButtonPushed(app, event)
            if app.HoldGraphSwitch.Value==0
                  hold(app.Graph, 'off')
            else
                hold(app.Graph, 'on')
            end
plot(app.Graph,x,y)
end
Any solutions would be appriciated 🙂 Thanks!

The hold command only tells it how to treat the next plot. Clearing your axes is a different process. There are numerous ways to do it, so it depends what functionality you want.
Consider using cla(app.UIAxes). You can read more about cla here .
Other options include clearing the line object's XData , YData, ... properties.
