from pylab import *
# make a square figure and axes
figure(1, figsize=(6,6))
ax = axes([0.1, 0.1, 0.8, 0.8])
# the slices will be ordered
# and plotted counter-clockwise.
labels = 'Spring', 'Summer', 'Autumn', 'Winter'
# fractions are either x/sum(x) or x if sum(x) <= 1
x = [15, 30, 45, 10]
# explode must be len(x) sequence or None
explode=(0.1, 0.1, 0.1, 0.1)
pie(x, explode=explode, labels=labels,autopct='%1.1f%%', startangle=67)
