Hello,
I need to display a point coordinate in a scatter plot, it works well, I just have to hover my cursor over it:
However, I also need to know my cursor's position when i clic, to do so I created a WindowButtonDown callback on the UIFigure.
But now my point's coordinate doesn't show anymore when I hover my mouse over it,
Do you have any idea where the problem can come from?
I recreated the issue in the attached file
Thank you for your help!

Hello Thomas,
I acknowledge that you are unable to know your cursor’s position after creating a ‘ButtonDownFcn’ callback.
I would recommend you to try this method out:
  1. Click on the ‘datatip’ tool on the top right of the figure.
  2. Now, you can hover over the point to view the coordinates data in a box (datatip).
It might be possible that the new ‘ButtonDownFcn’ callback overrides the existing method of click-or-hover to view the datatip.
Refer to the documentation attached to understand more about ‘datatip’ tool:
Hope this helps!
