Dear all, I want to get the position of crusor in an Axes without clicking on it. How can I do this ?
I read this one solution http://www.mathworks.com/support/solutions/en/data/1-1V97EZ/?solution=1-1V97EZ but currentpoint of Axes is the Location of last button click, I have to manage it wihout click.
Thank you in advance

This link shows you how to get the data. You do not have to click anywhere, but you have to find a way to store the data in an array. The example gives it as a title in the figure, so you can figure out yourself how to save it, right?

This gets the absolute coordinates of the pointer:
get(0, 'PointerLocation')
Getting the local coordinates relative to an AXES of FIGURE is not trivial in Matlab 2009a for docked figures. The commands OVEROBJ and HITTEST might be helpful also.

This is a brilliant fcn! I still have to click on the figure. Because I use axes instead of figure, I use timer fcn to call back instead of WindowButtonMotionFcn.
Thank you
