ox• For box definition, initialRect is [x y 0 0], where (x,y) is the figure’sCurrentPoint.• For box resizing, initialRect defines the rectangular region that you resize(e.g., a legend). fixedPoint is the corner diametrically opposite the trackingpoint.rbbox returns immediately if a button is not currently pressed. Therefore, youuse rbbox with waitforbuttonpress so that the mouse button is down whenrbbox is called. rbbox returns when you release the mouse button.ExamplesAssuming the current view is view(2), use the current axes’ CurrentPointproperty to determine the extent of the rectangle in dataspace units:k = waitforbuttonpress;point1 = get(gca,'CurrentPoint');finalRect = rbbox;point2 = get(gca,'CurrentPoint');point1 = point1(1,1:2);point2 = point2(1,1:2);p1 = min(point1,point2);offset = abs(point1-point2);% button down detected% return figure units% button up detected% extract x and y% calculate locations% and dimensionsx = [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 onaxis manualplot(x,y)% redraw in dataspace unitsSee Alsoaxis, dragrect, waitforbuttonpress2-385
