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'
完整追溯
/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:

535 color, palette, saturation):
536
--> 537 self.establish_variables(x, y, hue, data, orient, order, hue_order)
538 self.establish_colors(color, palette, saturation)
539 self.estimate_densities(bw, cut, scale, scale_hue, gridsize)
/Users/jrs/anaconda/lib/python3.5/site-packages/seaborn/categorical.py in establish_variables(self, x, y, hue, data, orient, order, hue_order, units)
145 if isinstance(input, string_types):
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)
