How to find axes in gui?
显示 更早的评论
Hi,
I'm trying to plot sth on axes2 in a gui, I think first I must find the axes2 and then set it as current axes.
But MATLAB could not find axes2, despite it can find all axes objects in figure.
ax=findobj(gcf,'Tag','axes2')
axes(ax);
What can be the problem?

If axes2 is stored in the handles structure, you can directly use
axes(handles.axes2)
Is it the case? As for the cause of your problem, maybe you have more than 1 figure opened and the current figure is not the one containing axes2?

Certain plotting functions, including cla, can reset the axes's tag. As Ben11 says, the better option is to store the handle somewhere permanent (i.e. in the handles structure, which if you're using GUIDE happens automatically) and access it from there.
If you need to rely on findobj, you need to be careful that you don't use any functions that would reset the properties you're using to test with findobj.

I faced the same problem trying to actualise the resulting image after parameter changes. In my case I used more than one figure, and I wanted to display the result on axes of my last figure after a pushbutton:
ok_mask_button= uicontrol(handles.pan,'Style','pushbutton','Units', 'normal', 'Position',[.55 .9 .08 .06],'FontSize',12,'FontWeight','bold', 'String','Ok','Callback', @Mask_parameters);
So to display the image using my callback function, the solution was :
% some code above%
...
ax = gca;
imshow(handles.mask,'Parent',ax)
