Grouping Plots within an Axes

Hello, I'm using plot() to draw elements of several physical mechanisms onto a set of UIAxes. Some elements might be represented as a single line between two points, and others might be as a triangle (three points), and others might use more points. As part of my app, I need to be able to regularly delete/re-draw various groups of elements. I'm currently assigning each element to a variable e.g. Element1 = plot(Element1_x, Element1_y), so that I can later use delete(Element1) when I need to delete/re-draw it. However this process is messy, as there are dozens of elements. I'm wondering if there is a way to group up multiple plots within one variable, so that I can simply use delete(Group1) to delete a specific group of plots from my axes.

Use indexing,
Element(i,num_group) = plot(Element1_x, Element1_y);
when delete all your elements in group 1,
delete(Element(:,1));
