6.饼图

饼图: 

# 饼图
fig = plt.figure(figsize=(7,7))
# 标签
labels = ['Frogs', 'Hogs', 'Dogs', 'Logs']
# 角度百分比,和为100%
sizes = [15, 30, 45, 10]
# 离开中心的距离
explode = (0, 0.1, 0, 0)
# shadow阴影,数字显示形式1.1f%, startangle起始角度
plt.pie(sizes,labels=labels,explode=explode,shadow=True,
        autopct='%1.1f%%',startangle=90)
plt.show()

效果如图:
