# method 2: gridspec
#########################
plt.figure()

# method 3: easy to define structure
####################################
f, ((ax11, ax12), (ax13, ax14)) = plt.subplots(2, 2, sharex=True, sharey=True)
ax11.scatter([1,2], [1,2])

plt.subplots_adjust(wspace = 1, hspace = 0.4) #调整子图间距
plt.tight_layout()
plt.show()
