[Matplotlib-users] detect mouse clicks

[Michael M. <mic...@gm...>]

For my application which is a simple sound file editor written with
matplotlib and PyQt4, I want to detect left and right clicks on the canvas.
I need to know the data coordinates of the click (i.e., not where on the
screen the click occurred, but what data point as defined by the axes it
represents). How do I do this?
