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?

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

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.
