Re: [Matplotlib-users] making (very simple) Venn diagrams?

[Jonathan T. <jon...@ut...>]

Try this:

from matplotlib import pyplot as plt
from matplotlib.patches import Circle

f = plt.figure()
ax = f.gca()
rad = 1.4
c1 = Circle((-1,0),rad, alpha=.2, fc ='red')
c2 = Circle((1,0),rad, alpha=.2, fc ='blue')
c3 = Circle((0,1),rad, alpha=.2, fc ='green')
ax.add_patch(c1)
ax.add_patch(c2)
ax.add_patch(c3)
ax.set_xlim(-3,3)
ax.set_ylim(-3,3)
plt.show()
