How to keep a patch object and its rotation in the same plot

Question

0 个投票

How can I keep the two following objects in the same plot. I tried to use 'hold on' but I did not work. I think that the object is dissappeared after rotating but I could not find a solution. (I have read this: https://www.mathworks.com/matlabcentral/answers/328222-two-patches-in-one-figure. But it could not help)

bot = patch(x,y,'blue');
hold on
rotate(bot, [0 0 1], 45)

Thanks.

Try this:

x = [1 2 2 1];
y = [1 1 2 2];
figure
bot = patch(x,y,'blue');
rotate(bot, [0 0 1], 45)
hold on
patch(x,y,'blue')
hold off
axis equal

You did not specify what your ‘x’ and ‘y’ are. This works with mine. It simply requires a second patch call.

alternatively copyobj the patch before rot()
