Hi all,

I am using "locator" to select the points from a scatter plot...

This is all fine.

But the problem is that the locator only returns the axis values of the
selected points.

Instead, I would like to get the index of these select points...

The axis values are real-values so it's a bit hard for me to directly
reverse-engineer the index nubmers..

How to do that?

Thank you!
