How to prevent overlapping x-axis labels in sns.countplot
提问by william007
For the plot
对于情节
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?
我得到了下图，x 轴标签混合在一起，我该如何避免这种情况？我应该改变图形的大小来解决这个问题吗？

Having a Series dslike this
有一系列ds这样的
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.
有几个选项可以使轴标签更具可读性。
Change figure size
更改图形大小
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
旋转刻度标签
ax = sns.countplot(x="Column", data=ds)
ax.set_xticklabels(ax.get_xticklabels(), rotation=40, ha="right")
plt.tight_layout()
plt.show()
Decrease Fontsize
减小字体大小
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.
当然，这些的任何组合都会同样有效。
Setting rcParams
设置rcParams
The figure size and the xlabel fontsize can be set globally using rcParams
可以使用rcParams全局设置图形大小和 xlabel 字体大小
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.
这对于放置在 juypter notebook 顶部可能很有用，以便这些设置适用于其中生成的任何图形。不幸的是，使用 rcParams 无法旋转 xticklabels。
I guess it's worth noting that the same strategies would naturally also apply for seaborn barplot, matplotlib bar plot or pandas.bar.
我想值得注意的是，同样的策略自然也适用于 seaborn barplot、matplotlib bar plot 或 pandas.bar。

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().
如果您只是想确保 xticks 标签不会挤在一起，您可以设置适当的 fig 大小并尝试fig.autofmt_xdate().
This function will automatically align and rotate the labels.
此功能将自动对齐和旋转标签。

You can rotate the x_labelsand increase their font size using the xticksmethods of pandas.pyplot.
您可以x_labels使用 的xticks方法旋转和增加它们的字体大小pandas.pyplot。
For Example:
例如：
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'
)
