python seaborn barplot bars not centered?

Question

I have never seen this before, but a seaborn barplot I am making just will not evenly space the bars...

Code

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)

Data

    Response    OrderCount  OrderAvgSize    AvgDeliverCost  AvgOrderValue   CustomerValue
CustomerID

Any ideas why this could be? Could it be something with the tick marks? I tried changing the size and rotation to no avail. It would just look a lot more aesthetically pleasing if the bars were evenly spaced and directly above their respective tick marks. It only appears to happen whenever there is a red bar after multiple blue bars. I am not sure what to try in order to fix this...

Answer 1

That's because your data has only one bar per ticks while with hue it's supposed to have 2 bars per tick (one for each category). Try passing dodge=False to sns.barplot :

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

Output:
