Can't create second axes in the place of first axes in GUI. is that a bug?

Hi,

I try to draw two images one on another, like background image and foreground and then the foreground image make half a transparent. More than that I want to do two different colormaps in the pictures. However when I create second axes in the gui I dont see it's created, I see in the properties the right clim the right boundaries in X and Y but I dont see the image in GUI, just nothing happens.

I have two 40X40 matrices (handles.topography_trace,whole_matrix_sum).

clim_raman = [min(whole_matrix_sum(:)), max(whole_matrix_sum(:))];


clim_topography = [min(handles.topography_trace(:)), max(handles.topography_trace(:))];

cla(handles.axes1);%here I clean image if I have it from the previous itteration

axes(handles.axes1);%here I point on the axes I want to draw the picture

ax1=handles.axes1;% I call it ax1


hB = imagesc(whole_matrix_sum,clim_raman);%here I draw the picture in that axes

hold on;% keep that figure on

ax2=axes('Position',ax1.Position);%here I should create another axes on the same position as ax1. But I dont see it's creating!!!

hF = imagesc(handles.topography_trace,clim_topography);% here it should draw the picture in the ax2, but it doesnt draw!!!!!

linkaxes([ax1 ax2]); % here I link 2 axes.

colormap(ax1,'jet'); %raman % here it should create the picture in ax1 in jet colormap
colormap(ax2,'parula'); % here I do half a transparent the second foreground picture.

hB.AlphaData=double(whole_matrix_sum > 0);% here I make transparent all the points in the matrix which are zeros
hF.AlphaData=0.5;% here I do half a transparent the second foreground picture.

The problem I dont see the second axes is created in GUI. I dont see the second picture (hF) is creating. In properties I see the right clim for ax1 and for ax2, but I dont see that axes is creating!!!!

Actually I try to do it with just a picture outside the GUI and it works but in the case of GUI it doesnt work.

function link2axes(whole_matrix_sum,topography_trace)

figure;
ax1=axes;
raman=imagesc(whole_matrix_sum);
ax2=axes;
topography_image=imagesc(topography_trace);

linkaxes([ax1,ax2]);
ax2.Visible = 'off';
ax2.XTick = [];
ax2.YTick = [];

colormap(ax1,'jet'); %raman
colormap(ax2,'parula'); %topography

set(raman, 'AlphaData', double(whole_matrix_sum > 0));
set(topography_image, 'AlphaData', 0.6);

Please help me.

Thank you.
