This is a picture of a scatter plot that I have plotted over an image from my raw data. I want to know the coordinates of the points that are inside the rectangle box that I have drawn. The raw data containing coordinates of all the scatter points is huge. So, is it possible to extract the coordinates of those group of points from the raw data alone somehow? Thank you! 댓글을 달려면 로그인하십시오.

Something like this perhaps:
hs = scatter(randn(1,1000),randn(1,1000),'.');
hr = rectangle('Position',[.5 .5 .65 .5]); minx = hr.Position(1);
maxx = hr.Position(1) + hr.Position(3);
miny = hr.Position(2);
maxy = hr.Position(2) + hr.Position(4);
mask = hs.XData >= minx & hs.XData <= maxx ...
& hs.YData >= miny & hs.YData <= maxy;
hold on
scatter(x,y,'filled') 댓글을 달려면 로그인하십시오.
