How to rotate xticklabels in a seaborn catplot

I'm not able to rotate my xlabels in Seaborn/Matplotlib. I have tried many different solutions but not able to fix it. I have seen many related questions here on stackoverflow, but they have not worked for me.

My current plot looks like this, but I want the xlabels to rotate 90.

@staticmethod
def plotPrestasjon(plot):
    sns.set(style="darkgrid")
    ax = sns.catplot(x="COURSE", y="FINISH", hue="COURSE",
                     col="BIB#", data=plot, s=9, palette="Set2")
    ax.set(xlabel='COURSES', ylabel='FINISH (sec)')
    plt.show()

I have tried:

ax.set_xticklabels(ax.get_xticklabels(), rotation=90)

But that fails to generate the plot. Any ideas how I can fix it?

• The correct way to set the xticklabels for sns.catplot, according to the documentation, is with the .set_xticklabels method (.e.g. g.set_xticklabels(rotation=30)).
• Using a loop to iterate through the Axes, should be used if changes need to be made on a plot by plot basis, within the FacetGrid.
• Building structured multi-plot grids
• seaborn.FacetGrid
• g, or in the case of the OP, ax is a seaborn.axisgrid.FacetGrid
  • When iterating through ax.axes.flat, axes is a <class 'matplotlib.axes._subplots.AxesSubplot'>, which has a wide array of class methods, including .get_xticklabels().
• In cases with many columns, and col_wrap= is used, g.set_xticklabels(rotation=30) may result in removing all the xticklabels.
  • Instead, labels= must be specified, g.set_xticklabels(g.axes.flat[-1].get_xticklabels(), rotation=30), where g.axes.flat[-1] should be the last facet axes with xticklabels.
  • Alternatively, use g.tick_params(axis='x', rotation=30)
• Tested in python 3.12, matplotlib 3.8.1, seaborn 0.13.0

One Row & Multiple Columns

import seaborn as sns

# load data
exercise = sns.load_dataset("exercise")

# plot catplot
g = sns.catplot(x="time", y="pulse", hue="kind", col="diet", data=exercise)

# set rotation
g.set_xticklabels(rotation=30)

Multiple Rows & Columns

# plot catplot
g = sns.catplot(x="time", y="pulse", hue="diet", col="kind", col_wrap=2, data=exercise)

# set rotation using one of the following options
# g.set_xticklabels(labels=g.axes.flat[-1].get_xticklabels(), rotation=30)
g.tick_params(axis='x', rotation=30)

• Using g.set_xticklabels(g.get_xticklabels(), rotation=30) results in an AttributeError.
