How to extract x, y data for particular/selected points from a scatter plot?

In a figure created using scatter plot in matlab, how do select particular points and extract x and y values for the same set of selected points?

How you want to select? You want to select manually by clicking on plot? What data you have?

Yes!

Read about getpts, ginput. These functions will help to pick points.

[x,y] = getpts() ;  % double click to exit
[x,y] = ginput(4) ;  % you can specify number of points

I suggest you consider using data brushing.

this also works, but because my scatter plots are curving in a certain way, selecting different points is easier with getpts. thank you so much for the help. it will deifinitely be helpful in other tasks.
