How to control the pushbutton in a while loop in Matlab GUI

Hi all,
I am now writting a pushbutton callback function by using a while loop like below
while i > 0 ;
var = get(handles. pushbutton, ' value');
if var ==1
plot(x,y);
else
error('range quitting')
end;
end
However, by this way, the pushbutton will automatically be clicked and the while loop will run continously.
I would like to run the loop each time only when I click the pushbutton.
Can anyone help me to solve the problem?
Many thanks.

I don't know whether you're using app designer, GUIDE, or a custom GUI/App which prevents me from getting too specific. I'm not sure what this means: " the pushbutton will automatically be clicked". Also, where is this while-loop and what is i? It's not clear why a while-loop is needed.
Here the general steps you can take.
  1. If the button should produce a figure, assign a callback function to the button and move the plotting code to the callback function. The code will be evoked when the user pressed the button.
  2. If the button should start/stop a longer plotting process such as an animation or updating a plot according to incoming data, you could use a state button (on/off states) that determines when the plotting should happen or pause. Keep in mind that when a callback function completes, its variables are cleared so you'll have to store the progress somewhere so the plotting function can pick up where it left off next time it's evoked.
