我被要求制作一些分类数据的饼图。

在一个简单的范围内，它看起来像这样：

House 1: Speak a foreign language , own a computer
House 2: Only lived in by women
House 3: Only lived in by women, speak a foreign language
House 4: Has pets
House 5: Has pets, own a computer
House 6: Speak a foreign language.

他们想要一个饼图来显示不同类别的百分比。

Well if I go:
Speak a foreign language  = 3/6
Own a computer = 2/6
Only lived in by women = 2/6
has pets = 2/6

这总计 9/6（即超过 100%）

我是否应该总计有多少个单独的项目，然后从中创建我的 %'ages

IE

Speak a foreign language  = 3/9
Own a computer = 2/9
Only lived in by women = 2/9
has pets = 2/9

这使得 100% 但我不确定这是否是你会这样做的，所以所有数据都显示在一个饼图中。
