How to close a figure made in one function, from a different function
显示 更早的评论
Im making a program that graphs data and several buttons. One button plots graph A and another button plots graph B. When I click the button that graphs plot B I want plot A to close and plot B to open, I added close(ax) to function B but I get an error that the variable ax doesnt exist. How do I define ax in function B so that I can close Plot A before plot B pops up? Thanks!

You don't. You create ax in function A (it is obtained from the plotting command that creates the graph), save it somewhere, and pass it to function B when it is needed there.
If this were being done in appdesigner, it would be a routine matter to save ax to a property of the app object, which gets passed around automatically to all the button callbacks in the app.

Hf=createPlot(1:5,rand(1,5));
closePlot(Hf);
function fig=createPlot(x,y)
fig=ancestor(plot(x,y),'figure');
end
function closePlot(fig)
close(fig)
end
