Drawrectangle on multiple tiles or figures using clickcallback

I have been able to add rectangles with drawrectangle with the mouse click callback, like this:

My main code for plotting:

ti1=nexttile;

im1=imagesc(pspp.pos_c_mm,pspp.pos_z_mm,dummie2);

ti3=nexttile;

im2=imagesc(pspp.pos_c_mm,pspp.pos_z_mm,dummie);

ti5=nexttile;

im3=imagesc(pspp.pos_c_mm,pspp.pos_z_mm,asymmetry);

linkaxes([ti1 ti3 ti5],'xy')

set([im1 im2 im3],'ButtonDownFcn',@ImageClickCallback);

My callback function:

function ImageClickCallback (objectHandle , eventData )

axesHandle = get(objectHandle,'Parent')

coordinates = get(axesHandle,'CurrentPoint');

coordinates = coordinates(1,1:2)

drawrectangle('Position',[coordinates(1)-10,coordinates(2)-10,20,20],'StripeColor','g','LineWidth',0.2);

end

With this I'm able to draw the rectangle in the image where the click was perfromed, and I would like to draw the rectangle in the 3 images simultaneously , so no matter what image you click, you will add in that same location a rectangle in the 3 images. Is that possible?

The 3 images have the same width and length.

In future questions, I recommend using the code formatting tools to make your post easier to read (and thus more likely to get a response).

Absolutely! Thanks for the recommendation!

When you call drawrectangle, you need to indicate which axes/tile you want to draw into. If you call drawrectangle three times, this should raw the same rectangle in each tile.

drawrectangle(ti1,'Position',[coordinates(1)-10,coordinates(2)-10,20,20],'StripeColor','g','LineWidth',0.2);
drawrectangle(ti3,'Position',[coordinates(1)-10,coordinates(2)-10,20,20],'StripeColor','g','LineWidth',0.2);
drawrectangle(ti5,'Position',[coordinates(1)-10,coordinates(2)-10,20,20],'StripeColor','g','LineWidth',0.2);

Depending on how the rest of your code is structured, you may need to pass the axes handles into your callback function. For example, modify your callback like this to pass your axes/tile handles into the callback:

set([im1 im2 im3],'ButtonDownFcn',@(o,e) ImageClickCallback(o,e,ti1,ti3,ti5));

Then modify your callback function to have three more inputs:

function ImageClickCallback (objectHandle, eventData, ti1, ti3, ti5)

Thank you so much Benjamin! Works like a charm!
