You'll probably want to use a regular poly collection, as in the
example below. Your array of facecolors can pretty much be whatever
you want:
from pylab import figure, nx, show, cm
from matplotlib.collections import RegularPolyCollection
fig = figure()
ax = fig.add_subplot(111)
offsets = nx.mlab.rand(20,2)
facecolors = [cm.jet(x) for x in nx.mlab.rand(20)]
black = (0,0,0,1)
collection = RegularPolyCollection(
fig.dpi,
numsides=5, # a pentagon
rotation=0,
sizes=(50,),
facecolors = facecolors,
edgecolors = (black,),
linewidths = (1,),
offsets = offsets,
transOffset = ax.transData,
)
ax.add_collection(collection)
show()
