See ginput: this allows to select an arbitrary point on a plot using
the mouse and to get the corresponding X-Y values in axes
corrdinates. If you want to select a point of an existing line,
then you can use ginput to get an arbitrary point and find the
closest data point using the minimum distance between data
points and the clicked point.
