Nested pie添加图例：王老师，请问pie图的legend如何调试，为什么只能显示起始颜色？谢谢王老师

参考这个：

1. x = [1, 3, 0.5, 2.5, 2]
   
2. size = 0.3
   
3. patchs, texts = pie(x, startangle=90, autopct='%.1f%%', \
   
4.     wedgeprops=dict(edgecolor='w',linewidth=2,width=size))
   
5. pie(x, startangle=90, radius=1-size, cmap='GMT_seis', \
   
6.     wedgeprops=dict(edgecolor='w',linewidth=2,width=size))
   
7. title('Pie chart')
   
8. legend(patchs, ['a','b','c','d','e'], loc='custom', x=0.75, y=0.5)

x = [1, 3, 0.5, 2.5, 2]<br /> size = 0.3<br /> patchs, texts = pie(x, startangle=90, autopct='%.1f%%', \<br />     wedgeprops=dict(edgecolor='w',linewidth=2,width=size))<br /> pie(x, startangle=90, radius=1-size, cmap='GMT_seis', \<br />     wedgeprops=dict(edgecolor='w',linewidth=2,width=size))<br /> title('Pie chart')<br /> legend(patchs, ['a','b','c','d','e'], loc='custom', x=0.75, y=0.5)

王老师，请问Nested Pie图按照示例添加图例之后如何将外围数字标签去掉，只去掉autopct='%.1f%%'语句之后会报错，请王老师指点。脚本与报错如下：
x = [1.9, 10.8, 11.0, 2.0, 1.6, 2.7, 0.9, 24.7, 37.8, 6.6]
y=[3.2,10.9, 22.4, 1.0, 14.7, 2.8, 0.2, 3.1, 35.1, 6.4]
size = 0.3
patchs,text = pie(x, startangle=90, radius=1, colors=[(0,255,255),(0,0,255),(94,114,255),(255,128,0),(255,0,0),(255,128,128),(0,255,0),(255,255,0),(194,61,22),(0,0,187)],\
    wedgeprops=dict(edgecolor='w',linewidth=0.01,width=size))
pie(y, startangle=90, radius=1-size, colors=[(0,255,255),(0,0,255),(94,114,255),(255,128,0),(255,0,0),(255,128,128),(0,255,0),(255,255,0),(194,61,22),(0,0,187)],\
    wedgeprops=dict(edgecolor='w',linewidth=0.1,width=size))
title('Pie chart')
legend(patchs, ['a','b',c','d','e','f','g','h','h2','h3'], loc='custom', x=0.75, y=0.5)
报错：patchs,text = pie(x, startangle=90, radius=1, colors=[(0,255,255),(0,0,255),(94,114,255),(255,128,0),(255,0,0),(255,128,128),(0,255,0),(255,255,0),(194,61,22),(0,0,187)],\

patchs, text = ...
改为：

参考这个脚本：

1. x = [1, 3, 0.5, 2.5, 2]
   
2. patchs, texts = pie(x, explode=[0,0.1,0,0.1,0], startangle=90, autopct='%.1f%%')
   
3. title('Pie chart')
   
4. legend(patchs, [u'中',u'国','c','d','e'], loc='custom', x=0.75, y=0.5,
   
5.     fontname=u'宋体')

x = [1, 3, 0.5, 2.5, 2]<br /> patchs, texts = pie(x, explode=[0,0.1,0,0.1,0], startangle=90, autopct='%.1f%%')<br /> title('Pie chart')<br /> legend(patchs, [u'中',u'国','c','d','e'], loc='custom', x=0.75, y=0.5,<br />     fontname=u'宋体')
