Hi
I have a contourf. I'd like to just add a simple Star or Triangular shape to certian location within the plot. I am thinking to use Patch() but patch still requires to provide the vertext of this Star or triangular shape in order to draw it. Is there a command to add this shape without knowing their vertex? Thanks

hi roudan, you can show your code how you saved your handles. the following worked for me without problems:
Z = peaks;
contourf(Z); hold on;
mark=plot(15,10,'rp','MarkerSize',15,'MarkerFaceColor','r');
delete(mark)
