How to draw shapes in uiaxes on app designer?

Hey for drawing circles you can use rectangles with 'Curvature' set to [1 1] which will round corners of rectangle and you can achiev circle. Try to use:

rectangle(app.UIAxes, 'Position', [25,25,50,50], 'Curvature', [1 1])

Has anyone successfully used the viscircles function in app designer? I am getting the following error:

Error using uistack (line 53)

Functionality not supported with figures created with the uifigure function. For more information, see Graphics Support in App Designer.

Error in viscircles (line 165)

uistack(thinCircHdl,'up');

I couldn't figure out how to use the viscircles but the rectangle function can do the same job.

By using the following for loop you will ensure that all detected circles are highlighted/filled

circlesize = 15;

cs = circlesize;

for i=1:max(size(centers))

rectangle('Parent', axisofinterest,'Position',[centers(i,:) -cs cs cs], 'Curvature',[1,1]);

end

This should work. You will obviously have to tweak the positioning parameters. Still, the viscircles is more desirable bcz its faster. If you figure out to incorporate viscircles, lemme know.
