From: Jean on 20 May 2010 08:46 Thank you again Matt, Unfortunately, my problem is that the code i posted works perfect in an application i did a year ago (and it still works). Now if I try the same thing on a new application I have no errors, but it does not give me the coordinates of the current point when I click on a plot. I appreciate your advice and your expertise, Jean.

From: Jean on 24 May 2010 18:34 Hello, After many attempts, I managed to solve the problem. The solution is assigning the same axes button down function to the plot I am doing into the axes: pp3 = plot(handles.axes3,dp3,'r'); set(pp3,'ButtonDownFcn',@axes1_ButtonDownFcn); After that everything worked fine. A good day to you, Jean.

From: Eli on 26 May 2010 03:52 Hi Jean, I had the same problem and your solution worked for me - thank! Just one thing - In my case I used imagesc to display an image (rather than plot), and I had to set the image handle HitTest property to 'on' in addition to setting its button down property to the required function.
