This handle is an hggroup object that is a child of the axes object, ax. h = viscircles(centers_nodeXY, radii_inf_range, Besides it being easier to get the coordinates correct, there is another reason to do this. As the cliche goes, "practice makes perfect" lol. ## draw circles at [10 20] and [-10 -20] coordinates ## with radius of 10 and 20 respectively viscircles ( [10 20; -10 -20], [10 20]) h = viscircles (ax,centers,radii) draws circles and returns a handle to the circles created. I have considered clearing the axes entirely, but I need to be able to run this loop a minimum of 5 times so i would have to erase and re graph the data points at least 4 times which is not ideal. Therefore, the color codes Based on Below is the code I am using, and I have attached what the figure it produces. I have saved the group to a handle, but when I try to execute the delete(handle) command the circles still remain. So maybe the structure of the code is the same but the input variables differ. The easiest is, to actually plot a filled rectangle with full curvature: %// radius r = 2; %// center c = [3 3]; pos = [c-r 2*r 2*r]; r = rectangle ('Position',pos,'Curvature', [1 1], 'FaceColor', 'red', 'Edgecolor','none') axis equal h = viscircles ( ___) returns a handle, h, to the drawn circles. Before R2021a, use commas to separate each name and value, and enclose Sometimes you do have to backtrack and go line by line but not in this case. but the curvature of the rectangle has to be set to 1!
