You are looking for matplotlib.pyplot.figure. You can use it like this:

from matplotlib.pyplot import figure
figure(num=None, figsize=(10, 10), dpi=80, facecolor='w', edgecolor='k')

Here is a example of how to do it:

names = ['group_a', 'group_b', 'group_c']
values = [1, 10, 100]

plt.figure(1, figsize=(9, 3))

plt.subplot(131)
plt.bar(names, values)
plt.subplot(132)
plt.scatter(names, values)
plt.subplot(133)
plt.plot(names, values)
plt.suptitle('Categorical Plotting')
plt.show()
