一张图中每个列数据框的分布概率 [英] Distribution probabilities for each column data frame, in one plot

问题描述

我正在通过seaborn库sns.distplot()中的distplot为数据帧的每一列创建概率分布.对于一个情节我做

I am creating probability distributions for each column of my data frame by distplot from seaborn library sns.distplot(). For one plot I do

x = df['A']
sns.distplot(x);

我正在尝试使用FacetGrid&映射一次具有每个列的所有图 这样.但是根本不起作用.

I am trying to use the FacetGrid & Map to have all plots for each columns at once in this way. But doesn't work at all.

  g = sns.FacetGrid(df, col = 'A','B','C','D','E')
  g.map(sns.distplot())

推荐答案

我认为您需要使用melt将数据框重整为长格式，请参见以下MVCE:

I think you need to use melt to reshape your dataframe to long format, see this MVCE:

df = pd.DataFrame(np.random.random((100,5)), columns = list('ABCDE'))
dfm = df.melt(var_name='columns')
g = sns.FacetGrid(dfm, col='columns')
g = (g.map(sns.distplot, 'value'))

输出:
