Display pointer/crosshair on all four subplots(images) on a gui

Hello,

I creating a gui with four image plots. When I move a mouse on of the images I want to display a crosshair on all other images at the same location. Below code display the crosshair on just one other image; I want to do the same so that the cross hair is present on all 3 images. Any suggestions? Thanks.

 tag = get(get(0,'CurrentFigure'),'Tag'); % check which figure the mouse is on
    % if tracking is on and the mouse is on the slicer_mod figure
    if (handles.tracking == 1 && strcmp(tag,'mainFrame') == 1)
        h2 = findobj('type','line','-depth',3);
        delete(h2);

        % get the pointer coordinates w.r.t. the current panel
        point = get(handles.imageDisplay, 'currentPoint');
        point = point(1,1:2);
        point(3) = handles.pos(3);

        xLim = get(handles.imageDisplay, 'xlim');
        yLim = get(handles.imageDisplay, 'ylim');
        % check if the pointer is within the boundary of the current panel
        if (point(1) >= xLim(1) && point(1) <= xLim(2) && ...
                point(2) >= yLim(1) && point(2) <= yLim(2))
            % if so, mark corresponding point on the original panel
            axes(handles.imageDisplay2);
            h2 = findobj('type','line');
            delete(h2);
            hold on
             h2 = plot(point(1),point(2),'r+');
            hold off

        end

Bala - are you using three axes within a single GUI to display all three images? Or is each image in its own figure? Are you using the cross-hair to perform a specific action (copy, crop, etc.) that you want each image to handle?

Dear Geoff,

Thanks for your reply. Yes, I'm using 4 axes on a single GUI. Cross hair was used just for visual purposes. i.e. location of the crosshair in one image should be exactly same as the location in other 2 images and viceversa. Anyhow, I think i fiugred a way to do this. I had to hold each axes individually before plotting cross hair.(hold('axes1','on))

Thanks!
