Rotate label text in seaborn factorplot

Question

I have a simple factorplot

import seaborn as sns
g = sns.factorplot("name", "miss_ratio", "policy", dodge=.2, 
    linestyles=["none", "none", "none", "none"], data=df[df["level"] == 2])

The problem is that the x labels all run together, making them unreadable. How do you rotate the text so that the labels are readable?

Answer 1

You can rotate tick labels with the tick_params method on matplotlib Axes objects.

Answer 2

I had a problem with the answer by @mwaskorn, namely that

g.set_xticklabels(rotation=30)

fails, because this also requires the labels. A bit easier than the answer by @Aman is to just add

plt.xticks(rotation=45)

Answer 3

This is still a matplotlib object. Try this:

# <your code here>
locs, labels = plt.xticks()
plt.setp(labels, rotation=45)

Answer 4

If anyone wonders how to this for clustermap CorrGrids (part of a given seaborn example):

import seaborn as sns
import matplotlib.pyplot as plt
sns.set(context="paper", font="monospace")

# Load the datset of correlations between cortical brain networks
df = sns.load_dataset("brain_networks", header=[0, 1, 2], index_col=0)
corrmat = df.corr()

# Set up the matplotlib figure
f, ax = plt.subplots(figsize=(12, 9))

# Draw the heatmap using seaborn
g=sns.clustermap(corrmat, vmax=.8, square=True)
rotation = 90 
for i, ax in enumerate(g.fig.axes):   ## getting all axes of the fig object
     ax.set_xticklabels(ax.get_xticklabels(), rotation = rotation)


g.fig.show()

Answer 5

You can also use plt.setp as follows:

import matplotlib.pyplot as plt
import seaborn as sns

plot=sns.barplot(data=df,  x=" ", y=" ")
plt.setp(plot.get_xticklabels(), rotation=90)

to rotate the labels 90 degrees.

Answer 6

Any seaborn plots suported by facetgrid won't work with (e.g. catplot)

g.set_xticklabels(rotation=30) 

however barplot, countplot, etc. will work as they are not supported by facetgrid. Below will work for them.

g.set_xticklabels(g.get_xticklabels(), rotation=30)

Also, in case you have 2 graphs overlayed on top of each other, try set_xticklabels on graph which supports it.

Answer 7

For a seaborn.heatmap, you can rotate these using (based on @Aman's answer)

pandas_frame = pd.DataFrame(data, index=names, columns=names)
heatmap = seaborn.heatmap(pandas_frame)
loc, labels = plt.xticks()
heatmap.set_xticklabels(labels, rotation=45)
heatmap.set_yticklabels(labels[::-1], rotation=45) # reversed order for y

Answer 8

One can do this with matplotlib.pyplot.xticks

import matplotlib.pyplot as plt

plt.xticks(rotation = 'vertical')

# Or use degrees explicitly 

degrees = 70  # Adjust according to one's preferences/needs
plt.xticks(rotation=degrees)

Here one can see an example of how it works.

Answer 9

Use ax.tick_params(labelrotation=45). You can apply this to the axes figure from the plot without having to provide labels. This is an alternative to using the FacetGrid if that's not the path you want to take.

Answer 10

If the labels have long names it may be hard to get it right. A solution that worked well for me using catplot was:

import matplotlib.pyplot as plt
fig = plt.gcf()
fig.autofmt_xdate()
