I have to display an image in a GUI figure. In the figure there are two axes.
How can I tell
imshow
to display the image in the axis I want? With
plot
I could use
plot(handles.axis1,image)
but this doesn't work for imshow (<http://www.mathworks.it/it/help/images/ref/imshow.html>)! The code
imshow(handles.axis1,image)
is not allowed,
imshow
doesn't accept axis handles.
Any suggestion to solve this issue?

You can specify the axes in the call to imshow with the 'Parent' option:
imshow(yourImage, 'Parent', handles.axesImage);
or you can specify it with the axes function in advance of calling imshow():
axes(handles.axesImage);
imshow(yourImage);

I would be stunned and shocked if my second option did not also work. The function axes() switches the current axes to what you specify, and imshow() with no parent option will display in the current axes.

axes(handles.axis1);
imshow(YourImage)
And you can get handles to different axis using findobj:
hAxes = finobj(gcf, 'type' ,'axes');

Use 'xdata' and 'ydata'.
imshow(yourImage, 'XData', x, 'YData', y);

function UPLOAD_Callback(hObject, eventdata, handles)
% hObject handle to UPLOAD (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[file,path]=uigetfile('*.*','Select image');
loc=strcat(path,file);
pic=imread(loc);
axes(handles.AXES1);
imshow(pic);
Something similar works for me as i am uploading image via a callback from button whose tag is UPLOAD, and my axes name is AXES1

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
axes(handles.axesImage);
imshow('Lena.jpg');

Should be okay as long as lena.jpg is in your search path or current folder.
Explain what "not working" means to you? Is there an error message?

If you can't get it working, post what you have and say what you want to do or measure in your images.
But do it in your own, new post instead of in this 6 year old answer to someone else.
