matplotlib画简单的柱状_折线_饼图

import matplotlib.pyplot as plt
plt.rcParams['font.sans-serif'] = ['SimHei']  # 用来正常显示中文标签

data = ['2020/2/1','2020/2/2','2020/2/3','2020/2/4','2020/2/5']
hebei = [32,54,54,34,23]
shanghai = [43,57,67,66,65]


# 折线图
# plt.plot(data,hebei,color='red',label='河北')
# plt.plot(data,shanghai,color='blue',label='上海')
# plt.title('折线对照')
# plt.xlabel('日期')
# plt.ylabel('数量')

# plt.legend()
# plt.show()


# 柱状图
# 垂直柱状图
plt.bar(data,hebei,color='red',label='河北')

plt.legend()
plt.show()

# 水平柱状图
plt.barh(data,shanghai,color='blue',label='上海')

plt.legend()
plt.show()


# 饼状图
number = [666,354]
province = ['四川','重庆']
colors = ['#999fff','#fff999'] # 使用16进制的颜色码

plt.pie(x=number,labels=province,colors=colors)
plt.show()
