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?

  • This question is for axes-level functions (those with the `ax=` parameter), not figure-level functions. See [Figure-level vs. axes-level functions](https://seaborn.pydata.org/tutorial/function_overview.html#figure-level-vs-axes-level-functions). See [How to rotate xticklabels in a seaborn catplot](https://stackoverflow.com/q/63909351/7758804) for figure-level plots. – Trenton McKinney Jun 01 '23 at 20:13

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()

enter image description here

Decrease Fontsize

ax = sns.countplot(x="Column", data=ds)

ax.set_xticklabels(ax.get_xticklabels(), fontsize=7)
plt.tight_layout()
plt.show()

enter image description here

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.

You can rotate the x_labels and increase their font size using the xticks methods of pandas.pyplot.

For Example:

import matplotlib.pyplot as plt
plt.figure(figsize=(10,5))
chart = sns.countplot(x="HostRamSize",data=df)

plt.xticks(
    rotation=45, 
    horizontalalignment='right',
    fontweight='light',
    fontsize='x-large'  
)

For more such modifications you can refer this link: Drawing from Data

If you just want to make sure xticks labels are not squeezed together, you can set a proper fig size and try fig.autofmt_xdate().

This function will automatically align and rotate the labels.

I don't know whether it is an option for you but maybe turning the graphic could be a solution (instead of plotting on x=, do it on y=), such that:

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