Hi there,
i try to delete all rectangles drawn into a figure axes. When creating these Rectangles, they're saved to a struct which is present in the function where i want to delete the existing rectangles. How can i detect all objects of the type Rectangle, or is there a different way to gett all drawn rectangles in an figure axes?
I added a screenshot of the figure axes with one rectangle drawn in there in red:

Hi,
You can get all the Graphics Objects of the preferred type present in MATLAB figure using ‘findall’ function in MATLAB and then delete all the objects using ‘delete’ function in MATLAB.
For instance, try executing this code:
figure;
axis([0 10 0 10]);
rectangle(Position,[1 2 5 6]);
rect = findall(gcf,Type', 'Rectangle’);
delete(rect);
Refer to this documentation links:
