Hi,

For the life of me I cannot hide/show a graph on my axes when I click a checkbox. I've tried something like:

set(app.graph1, 'visible', 'off');

But of course this hides the axes not the data and I want the other way around. I've tried the following:

set(app.graph1.Children, 'visible', 'off');

This hides the axes content but I just want to hide a specific set of data on the axes. For example I had:

A=plot(app.graph1, time2, speed2, '--m');
hold(app.graph1, 'on');
B=plot(app.graph1, time2, power2, '--b');

So really I just want to hide for example B but keep A.

Thanks!

And set(B, 'visible', 'off');?

It doesn't work. Here is the code:

function Dataset1CheckBoxValueChanged(app, event)
value1=app.Dataset1CheckBox.Value;
A=[];
if value1==1
    set(A, 'visible', 'on');
    set(app.graph1, 'visible', 'on');
    app.dataset1=evalin('base', 'dataset1');
    time1=app.dataset1(:,5);
    power1=app.dataset1(:,10);
    power2=app.dataset1(:,13);
    A=plot(app.graph1, time1, power1, 'm');
    hold(app.graph1, 'on');
    B=plot(app.graph1, time1, power2, 'b');
else
    set(A, 'visible', 'off');
end
end
