[Baypiggies] Fwd: Venn diagram for five events

[Vikram K]

This works for four events and their intersections but how do i add the
fifth event along with all intersections?

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')
c4 = Circle((0,-1),rad, alpha=.2, fc ='yellow')
ax.add_patch(c1)
ax.add_patch(c2)
ax.add_patch(c3)
ax.add_patch(c4)
ax.set_xlim(-3,3)
ax.set_ylim(-3,3)
plt.show()

I sent the following query to the matplotlib list a while back. I would
appreciate it if someone here can answer my question. Also, is there an
alternative to matplotlib for this kind of a problem?

I wish to draw a Venn diagram depicting five events and their intersections.
I came across some code for three events--could someone please direct me
about how i could modify it for five events.

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()
