You can try datapoints and getpts.

Check function datacursormode.

I copy the example from the documentation and you can implement it into your code:

clear; clc;
x = 1:10;
y = x.^2;
scatter(x,y)
dcm = datacursormode;
dcm.Enable = 'on';
dcm.UpdateFcn = @displayCoordinates;
function txt = displayCoordinates(~,info)
    x = info.Position(1);
    y = info.Position(2);
    txt = ['(' num2str(x) ', ' num2str(y) ')'];
    fprintf('\nX = %.2f, Y=%.2f\n',x,y);                % I added this line so that you know what data are retrieved from this callball
end
