python seaborn barplot 条不居中？

Question

我以前从未见过这个，但是我正在制作的 seaborn barplot 不会均匀地间隔条形......

代码

fig, ax = plt.subplots(figsize=(25,6))

sns.barplot(x=value.index, y="CustomerValue", data=value, 
            order=value.index, hue='Response')

plt.xticks(fontsize=10, rotation=90)

数据

    Response    OrderCount  OrderAvgSize    AvgDeliverCost  AvgOrderValue   CustomerValue
CustomerID

知道为什么会这样吗？会不会是有刻度线的东西？我尝试更改大小和旋转无济于事。如果条形均匀分布并直接位于各自的刻度线上方，看起来会更美观。它似乎只在多个蓝色条之后有一个红色条时发生。我不确定要尝试什么来解决这个问题......

Answer 1

那是因为您的数据每个报价只有一个柱，而使用 hue 它应该每个报价有 2 个柱(每个类别一个)。尝试将 dodge=False 传递给 sns.barplot:

sns.barplot(x=value.index, y="CustomerValue", data=value, 
            order=value.index, hue='Response', dodge=False)

输出:
