'Title','',...
'BorderType','none',...
'Tag','uipanel',...
'FontSize',11,...
'Position',[0.0001 0.69 1.0 0.16]);

'Units',get(0,'defaultuipanelUnits'),...
'Title','Z-Domain Cascaded T/F ',...

'FontSize',11,...
'Position',[0.0001 0.5 0.5 0.50]);
ZDomainCascadedImageAX = axes(DigitalCompensatorImagePanel1,'Position',[0 0 1 1]);
ZDomainCascadedImage = imread('CascadedDisc.png');
imshow(ZDomainCascadedImage,'Parent',ZDomainCascadedImageAX);
set(ZDomainCascadedImageAX,'Units','pixels');
resizePosZDomainCascadedImageAX = get(ZDomainCascadedImageAX,'Position');
ZDomainCascadedImageResize=imresize(ZDomainCascadedImage, [resizePosZDomainCascadedImageAX(4) resizePosZDomainCascadedImageAX(3)]);
imshow(ZDomainCascadedImageResize,'Parent',ZDomainCascadedImageAX);
set(ZDomainCascadedImageAX,'Units','normalized');

The code would be
cla(ZDomainCascadedImageAX)
Your issue is more likely related to variable scope. The pushbutton will have it's own callback function. You need to somehow pass the axes handle into the pushbutton callback. Since it looks like you are creating this app programmatically, consider looking at this example for how to achielve that.
