Toggle visibility of plots, on the same figure?

Attached is the current state of my "project" for which I have SO MANY questions...

First, as I experimented with the script this morning, it dawned on me that my script value would be enhanced by a checkbox that would toggle on and off the visibility of the trisurf plot, so that, I could isolate the data points from the gamut volume to better study their relationship :

Adding a uicontrol checkbox to the script should not be difficult but I sense that I would have to restructure the script very differently? Such that, from the callback function I could issue the call to the trisurf function? Or are there figure or axes options I don't know about that would make this easier?

A search for "Show or hide figure plot" turned the Plot Browser!!!

Wow! Thank you Mathworks, it's almost what I want, as the figure is "frozen" (can't interact with it while the Plot Browser is active). But it's mighty strong!!

Almost there! This is what I have, now :

You can see my checkbox, top, left-hand, circled in red -- wow! I added this code to create the control :

cb = uicontrol('Style','checkbox','String','triSurf','Position',[10 500 75 150],'Value',1,'Callback',@checkBoxCallback);

cb.Visible = 'on';

Then I added this function to handle the callback :

function checkBoxCallback(source, event)

global h1;

value = get(source,'Value');

if value == 1

set(h1,'Visible','off');

else

set(h1,'Visible','on');

end

end

Problem is -- please excuse my ignorance -- the checkbox state? When the script is ran, initially, the Value = 1 option in the declaration sets the checkbox state to checked, as far as I can see. This is how the control shows up in the interface. I think it's logical to have the checkbox checked since the trisurf plot is initially visible. When I click on the ckeckbox, however, nothing happens : I have to click one more time and then, the checkbox becomes unchecked but the trisurf is still visible? It's only when I click a third time that the checkbox starts to work as 'expected'. I attached the new code. It's not the end of the world but...

One newbie question in passing, if I may...

I'm using global variables 'sparingly'... Are there better ways to do this, without getting too overly complex?

Just a small edit suggestion: you should store the handles you want to interact with in the guidata struct. That way you don't need global variables.

As for the other issue you mentioned, I don't understand your problem well enough to be able to solve it.

Right after initial launch, right after pressing the Run button, I get this :

As you can see, the checkbox is checked. Which is the expected behavior.

Now, this is what happens when I first try to uncheck :

The checkbox is unchecked -- yet, the plot is still visible?

I click the checkbox... and this is what I get :

Now the checkbox is checked YET the plot is not visible?

One more round of clicking and this is what I get :

Do you see what is going on? It is as though the checked state does not match the visibility of the plot.

I changed the initial value in the code back to 0 and changed my code in the function this way :

if value == 0

set(h1,'Visible','off');

else

set(h1,'Visible','on');

end

And now, everything is perfect!!!!

I'll take a look at the the guidata struct. Thanks for the leg up!
