this is the code im using.
axes(handles.axes1); UP = imagesc(imread('UP.jpg')); set(gca, 'XTick',[]); set(gca, 'YTick',[]); set(gca, 'XColor','w'); set(gca, 'YColor','w'); axes(handles.axes2); DOWN = imagesc(imread('DOWN.jpg')); set(gca, 'XTick',[]); set(gca, 'YTick',[]); set(gca, 'XColor','w'); set(gca, 'YColor','w'); set(handles.axes1,'hittest','off'); set(UP,'hittest','off'); set(handles.axes2,'hittest','off'); set(DOWN,'hittest','off');
I don't know what is gca used for. And also I have this part of the code which I don't know what is used for either.
_handles.xy1 = round(get(handles.axes1,'Currentpoint')); x1 = handles.xy1(1,1); y1 = handles.xy1(1,2);_
Sorry if this is a very simple question. This is all new to me.

Hi Jonathan,
The command sets the axis tick labels for the current figure. gca gets the axis of the current figure (Get Current Axis) XTick and YTick are the properties in which MATLAB stores the location of the respective tick marks

handles.axes2 is simply an axis handle i.e.
axis_handle = findobj(gcf,'type','axis')

set(gca, 'XTick', []) removes the tick marks from the x axis.
