Clearing GUI axis difficulty

I have a GUI that has two axis. The first axis is my original image and the second axis is my filtered image where I am able to apply various filters to change the image. I have a Reset command which I want to Reset both axis's to be blank to allow the user to input another image. I used the matlab command.
arrayfun(@cla,findall(0,'type','axes'))
Which clears both axis but when I load an image it loads it into the second axis and not the first axis. Then when I apply filters it just filters the second axis image leaving the first one blank. Any ideas how to fix this? I have tried storing both axis as global variables and then using cla but this gives me the same problem as before.

I see. I am building a GUI that shows images on an axis that I already have so I can't use the f = figure(). And when I run my code
OriginalAxis = findobj(gcf,'Tag','axes1');
set(gcf,'CurrentAxes',OriginalAxis);
[M,N] = size(X);
ax = axes('Parent',OriginalAxis);
imshow(X);
when I run this I get the error
Error using axes An object of class axes, can not be a child of class axes.
Is there any way around this?

OriginalAxis = findobj(gcf,'Tag','axes1');
imshow(X, 'Parent', OriginalAxis);

Use this code:
axes(handlesToAxes1);
cla('reset');
axes(handlesToAxes2);
cla('reset');

It doesn't work for me. Should it be handles.myAxisName also is it bad to call findobj multiple times in my code on the same object?
