Hello, I'm trying to rotate plot information(I was doing this before with handles) without graphing it. This is because this has to do with animations, and other things being animated on this same plot. I need to get this shape to rotate before plotting it, because running it in time will not work well if it is plotted, even for a short time, and then rotated. I need to do this with handles because I don't want a new figure, nor do I want this shape to be overwritten while I'm graphing it.

Can you use camroll()? you can set the plot invisible while you do this;

set(gcf,'Visible','off') %set invisble
camroll(gca,20) %rotate 20*
set(gcf,'visible','on') %set visible

If you want to rotate part of the contents of the plot (rather than wanting to rotate the plotting frame itself) then I suggest parenting the graphic to a hgtransform and use hgmaketform to create the appropriate rotation matrix. See https://www.mathworks.com/help/matlab/ref/hgtransform.html
