Thread Subject: GUi axes

Hi,
I have a problem with axes_GUI.
To solve it,I tried many ways which I have got from this
forum or others.And also I know that there are many similar
problem and their solution.Be sure that I have tried
them,but not get the exact solution.Pleae help me.
The problem is;
I made a simple GUI which includes two materials:an axes
and a push button.When I click the push button,I get the
pictures well.But I need to update them sometimes,so I need
to click the push button again,but have an error.
%%%%%%Error%%%%%%%%%%%

I tried it without "subplot",it is OK!
What is the problem with "subplot" in the GUI applications?

The problem is that in subplot, there may be several handles not a signle handle depending on which subwindow you are making your plot. So, there may be incroeect reference of the subplot handles which create your problem.

Thank you for your reply.
I have to use subplot,because when I used two axes to show
these two different picture,the axes width-height changes
and becomes bigger.I lost myself in the property editor of
axes,but could not solve it.

(Sorry for possible repeating in the message,I might be
confused it).
Thank you for reply.

height changes and becomes bigger.So I used subplot.

And what about closing/cleaning the axes,the re-show
again,when I click the pusbutton seconly?If so,how can I do
it?

Any idea,please?

Just a thought
Instead of using one axes and using a subplot function,
why dont you use 2 axes.
ex:
Drop down 2 axes from the guide menu on to your figure
Assuming the 2 axes are axes1 and axes2 respectively
In the pushbutton function use this;

axes(handles.axes1);%gives focus to first axes
imshow('image1.jpg');
drawnow;
axes(handles.axes2);%gives focus to second axes
imshow('image2.jpg');
drawnow;

Sorry did not read your other statements before posting.
If you are dealing with only one axes, just remove the
definition, axes(handles.axes1); from your Push Button
function.

You can declare the same in the opening fcn

First of all thank you for reply,
I have to use "subplot".Because I have to use "linkaxes"
command,and it works only for figures which drawn
by "subplot".with two different axes,it doesn't work.
In addition,there are many problems or troubles similar
with mine.But difference is "subplot".Because also I know
that If I dont use subplot,it is OK.

Thank you for help,
It is solved!
*The problem was "subplot in GUI".
*The solution lies on the "panel",not "axes".
*Graphics/plots should be drawn into the "panel",not "axes".
*Put a panel with tag property "xyz".
*code is;
a1=subplot(1,2,1,'Parent',handles.xyz);
imshow(I)
a2=subplot(1,2,2,'Parent',handles.xyz);
imshow(Q)
*At the end of this part,"linkaxes" (which is the reason of
using "subplot" instead of "two different axes") comes.
linkaxes([a1 a2],'xy')
*with this code the plot/show area can be fixed with panel
sizes without complexity of properties of axes.
Thank you.
