Easiest way of drawing a circle?

Community matplotlib-users

Hi,

I’m using wxpython with matplotlib, I now have a figurecanvas embedded in my program and I can plot stuff using:

a = self.fig.gca()
a.plot(x,y)

But what is the easiest and fastest way to draw a circle? I saw that the artist class has a draw_arc function… but I don’t know how to use the artist class with my figure canvas… Like I can’t do a.draw_arc() for instance …

Can anyone point me in the right direction?

Thanks,
Soren

from matplotlib.patches import Circle
cir = Circle( (0,0), radius=0.5)
a.add_patch(cir)
