我有一个pandas数据帧df,我正在尝试使用seaborn库创建一个小提琴图。

    rank  sentiment category
0     1   0.657413        m
1     2   0.895769        m
2     3  -0.435457        m
3     4  -0.717959        m
4     5   0.869688        m

这是seaborn系列:

sns.violinplot(x="rank", y="senitment", hue="category", data=df)

我不断得到这个ValueError

ValueError: Could not interpret input 'senitment'

/Users/jrs/anaconda/lib/python3.5/site-packages/seaborn/categorical.py in violinplot(x,y,hue,data,order,hue_order,bw,cut,scale,scale_hue,gridsize,宽度,内部,分裂,东方,线宽,颜色,调色板,饱和度,轴,** kwargs)        2299 bw,cut,scale,scale_hue,gridsize,        2300宽度,内部,分割,方向,线宽,      - > 2301色,调色板,饱和度)        2302        2303如果ax是None:

    538         self.establish_colors(color, palette, saturation)
    539         self.estimate_densities(bw, cut, scale, scale_hue, gridsize)

    146                     err = "Could not interpret input '{}'".format(input)
--> 147                     raise ValueError(err)
    148 
    149             # Figure out the plotting orientation

ValueError: Could not interpret input 'senitment'

我尝试在df和更改数据类型上使用.reset_index(),但没有运气。想法?

答案 0 :(得分:3)

sns.violinplot(x="rank", y="sentiment", hue="category", data=df)
