饼图简单绘制

import matplotlib.pyplot as lt
#显示中文
lt.rcParams[\'font.sans-serif\']=[\'SimHei\']
lt.rcParams[\'axes.unicode_minus\']=False
labels=\'Frogs\',\'Hogs\',\'Dogs\',\'Logs\'#图标签
sizes=[10,20,30,40]#图比例
colors=[\'yellowgreen\',\'gold\',\'lightskyblue\',\'lightcoral\']#饼图分布颜色
explode=(0,0.1,0,0)#突出显示数值
lt.pie(sizes,explode=explode,labels=labels,colors=colors,autopct=\'%1.1f%%\',shadow=True,startangle=90)
lt.axis(\'equal\')#显示为圆
lt.show()
