变量频率颜色值颜色的变量
值之和的比例；e、 g.变量“每月x.2-3次”的y值应为22/（22+45+344+5+1+0+4）或5.22%
到目前为止，我有：
import seaborn as sns
fig, ax1 = plt.subplots(figsize=(20, 10))
sns.factorplot(x='variable',y='value', hue='Frequency', data=df, kind='bar', ax=ax1)
这是通往那里的道路的一部分。如何按1）颜色和2）取每个变量和频率的值的比例，而不是计数进行分组？这就是您需要找到该组每个数字的部分的原因：
df['proportion'] = df['value'] / df.groupby(['Color','variable'])['value'].transform('sum')
输出：

在s/o上做什么洁食的事情？将你的答案标记为正确，然后问一个关于图表的新问题？或者顺其自然，看看是否有其他人回答？如果这回答了你的问题，你可以接受。然后，问一个关于图表的更简洁的问题。
