How to prevent overlapping x-axis labels in sns.countplot

Question

For the plot

sns.countplot(x="HostRamSize",data=df) 

I got the following graph with x-axis label mixing together, how do I avoid this? Should I change the size of the graph to solve this problem?

Answer 1

Having a Series ds like this

import pandas as pd import seaborn as sns import matplotlib.pyplot as plt import numpy as np; np.random.seed(136)  l = "1234567890123" categories = [ l[i:i+5]+" - "+l[i+1:i+6] for i in range(6)] x = np.random.choice(categories, size=1000,              p=np.diff(np.array([0,0.7,2.8,6.5,8.5,9.3,10])/10.)) ds = pd.Series({"Column" : x}) 

there are several options to make the axis labels more readable.

Change figure size

plt.figure(figsize=(8,4)) # this creates a figure 8 inch wide, 4 inch high sns.countplot(x="Column", data=ds) plt.show() 

Rotate the ticklabels

ax = sns.countplot(x="Column", data=ds)  ax.set_xticklabels(ax.get_xticklabels(), rotation=40, ha="right") plt.tight_layout() plt.show() 

Decrease Fontsize

ax = sns.countplot(x="Column", data=ds)  ax.set_xticklabels(ax.get_xticklabels(), fontsize=7) plt.tight_layout() plt.show() 

Of course any combination of those would work equally well.

Setting rcParams

The figure size and the xlabel fontsize can be set globally using rcParams

plt.rcParams["figure.figsize"] = (8, 4) plt.rcParams["xtick.labelsize"] = 7 

This might be useful to put on top of a juypter notebook such that those settings apply for any figure generated within. Unfortunately rotating the xticklabels is not possible using rcParams.

I guess it's worth noting that the same strategies would naturally also apply for seaborn barplot, matplotlib bar plot or pandas.bar.
