Here is a scatter plot consisting of arbitrary points.

Now we select some specific points in that scatter plot.

However, we want to return the coordinates of the selected point in the above figure to the main function. How to solve this problem, please.

I have tried to use the two functions you recommended, but I want to get the exact coordinates of the points (I am using getpts and ginput to get approximate coordinates of the points). In fact, the points in Figure 1 are known points, and the function I want to implement is to filter out certain anomalies from these known points by mouse interaction. Thank you very much.
