ButtonDownFcn question - different actions on different axes (using GUIDE)

Hi.
I am using a mouse down call back to plot a linescan on an image at the mouse location. This all works fine. My issue is that I only want this to happen if I am over a certain axes on my GUIDE layout (i.e. axes1). If I'm on another axes e.g axes2, then I want the mouse click to do something else.
When I display my image in axes 1 I do this:
axes(handles.axes1)
imageHandle=imshow(img,[low,high]);
set(imageHandle,'ButtonDownFcn',@ImageClickCallback); %assign to the buttondown function
I then have the ButtonDownFcn as:
function ImageClickCallback (objectHandle, eventData)
handles = guidata(objectHandle);
axesHandle=get(objectHandle,'Parent'); %Object handle is the image
coordinates=get(axesHandle,'CurrentPoint');
curX = coordinates(1,1)
curY = coordinates(1,2)
x=round(curX)
y=round(curY)
...then perform line scan
so is it possible to limit this mouseclick action just to the axes 1
axes(handles.axes1);
And how would I go about creating another function that operates on axes 2 when I press the mouse button
Thanks Jason

Yep. Most objects have their own ButtonDownFcn.
If you want to do things with mouse motion it is more difficult as only the Figure has a callback for that, but for button clicks you can be very specific.
