Hey Guys,
I ve read a lot of stuff for the last 2 hours but I still dont know how to use the Function. The Problem: My GUI reads Data and plots it in a new figure as subplot.(Figurename = Plot) Now I want to create a Push button, which uses somehow the ButtonDownFcn to give me the coordinates of where I clicked...... Qestions: How does the ButtonDownFcn work ? Is there a another alternative ? Can i Activate the datacursormode for my Plot-figure ?
Thanks

Do you want the coordinates of where you clicked at the pushbutton? Or where you click inside the plot? It's hard to understand exactly what you want to do.
If you just want to know how ButtonDownFcn works it's explained quite well in the documentation.

Why not have a push button where in the callback function, you call
uiwait(helpdlg('Click in the plot'));
[x, y] = ginput(1);
Your user clicks in the plot and ginput() returns the x and y of where they clicked.
