MATLAB: Where are all drawn shapes stored from an axis

Question

Let's say that I have an axis and I draw three shapes on it using drawrectangle.

Is there some way to call an array that holds the handles to each of these shapes?

Thanks

Answer 1

Store handles

In the block below, r1, r2, & r3 are handles to the 3 rectangles.

figure()
r1 = rectangle('Position',[0 0 2 4],'Curvature',0.2);
hold on
axis equal
r2 = rectangle('Position',[3 0 2 4],'Curvature',1);
r3 = rectangle('Position',[6 0 2 4],'Curvature',[0.5,1]);

Retrieve handles if they aren't stored

The line below search for objects of type "rectangle" in the current axes. For the plot created above, r would be a vector of object handles of size [3x1].

r = findobj(gca, 'Type', 'rectangle');
