回答： Juraj 2014-1-16

Hello,

I have a pcolor plot which has some symmetry and I want to emphasize it by adding an ellipse to the figure (just the line) - normally I would do it like this:

t=0:0.1:2*pi;
a=26;
b=25;
x=a*cos(t);
y=b*sin(t);
plot(x,y,'--')

Now I want to add it to the existing pcolor plot. How can this be achieved? I saw some similar problems here, but wasn't able to use it to solve my problem. Thanks in advance.

Nevermind, I managed to do it somehow. If anyone would be in need of something similar, here's my code:

figure
pcolor(x,y,Z);shading interp; colormap jet;axis square off
h_ax = gca;
h_ax_line = axes('position', get(h_ax, 'position'));
plot(X,Y,'g--');
set(h_ax_line, 'YAxisLocation', 'right', 'xlim', get(h_ax, 'xlim'),'ylim', get(h_ax, 'ylim'), 'color', 'none'); 
axis square off
