Coordinates related to rbbox in GUI

I programmed a GUI where there is a Axes in it. I try to select some objects in this Axes using rbbox.
The problem is that the return vector of rbbox is measured from the coordinate of whole GUI instead of the coordinate of Axes. How can I get the return vector whos reference coordinate is Axes in Gui?
Thank you in advance. Lin

You could just do like the example in RBBOX, and use the currentpoint property of the axes instead...
figure;
pcolor(peaks);
k = waitforbuttonpress;
point1 = get(gca,'CurrentPoint'); % button down detected
finalRect = rbbox; % return figure units
point2 = get(gca,'CurrentPoint'); % button up detected
point1 = point1(1,1:2); % extract x and y
point2 = point2(1,1:2);
p1 = min(point1,point2); % calculate locations
offset = abs(point1-point2); % and dimensions
x = [p1(1) p1(1)+offset(1) p1(1)+offset(1) p1(1) p1(1)];
y = [p1(2) p1(2) p1(2)+offset(2) p1(2)+offset(2) p1(2)];
hold on
axis manual
plot(x,y,'r','linewidth',5) % draw box around selected region
