Python Seaborn Plot ValueError
提问by Ryan
I have a pandas dataframe dfand am trying to use the seaborn library to create a violin plot.
我有一个Pandas数据df框，正在尝试使用 seaborn 库来创建小提琴图。
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
This is the seaborn line:
这是seaborn线：
sns.violinplot(x="rank", y="senitment", hue="category", data=df)
I keep getting this ValueError
我一直得到这个 ValueError
ValueError: Could not interpret input 'senitment'

I've tried using .reset_index() on the df and changing data types, but no luck. Thoughts?
我试过在 df 上使用 .reset_index() 并更改数据类型，但没有运气。想法？
