Python matplotlib subplot 複数のグラフを表示する

参考：

from pylab import *
x = arange(1, 10, 0.1)
y1 = sin(x)
y2 = cos(x)

# 上の行のグラフ
subplot(211)
plot(x, y1)
xlabel("1") # 上の行のxlabel

# 下の行のグラフ
subplot(212)
plot(x, y2)
xlabel("2") # 下の行のylabel

show()

例：

import MySQLdb
from pylab import *
import sys
import numpy as np
import matplotlib.pyplot as plt
import datetime
from matplotlib.dates import YearLocator, MonthLocator, DayLocator, DateFormatter

connection = MySQLdb.connect(host="localhost", db="agemono", user="root", passwd="password", charset="utf8")
cursor= connection.cursor()

cursor.execute(d)
datad = cursor.fetchall()

prodd =
datestring=[]

print 1212

monthsFmt = DateFormatter('%m')
days = DayLocator()

for row in datad:
prodd.append(row[0])

print 2222

print 33333
