python_简单的DB统计

import numpy as np
import pylab as pl
dates=['20170314','20170315','20170316','20170317','20170318','20170319']
x = range(len(dates))
y = [1974786,3502609,3824524,2046503,5623141]
y.append(5505794)
pl.plot(x,y,'ro-')
pl.xticks(x, dates, rotation=45)
pl.margins(0.08)
pl.subplots_adjust(bottom=0.15)
pl.grid(True)
pl.show()
