数据分析系列：完善统计图（matplotlib）

import matplotlib.pyplot as plt
import numpy as np

n = ["hubei","huangshi","wuhang","beijing","shanghai"]
m = [3,1,5,4,7]

#调整图表大小
plt.figure(figsize=(9,5))
#增加XY轴信息
plt.xlabel('region')
plt.ylabel("count")

plt_red, = plt.plot(n, m,color='red')
#增加图例
plt.legend(handles = [plt_red,], labels = ['red'], loc = 'best')
