Asking for help, clarification, or responding to other answers. What you can do instead is keep appending to your data so that the original data is displayed followed by a new circle each time you prompt for new data. You can use the imfindcircles function to find the centers and radii of circles in an image. viscircles by default will flush the figure and draw only the circles specified by the inputs you provide it so hold on will not work. I know I didn't make it very clear in the question, but I'm actually trying to get multiple colors of circles plotted. You can use the imfindcircles function to find the centers and radii of circles in an image. 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 The circles can overlap, or not, either is fine.
