无法更改图表上的刻度频率

问题描述

我看到了许多关于更改SO的变动频率的问题，这在构建折线图时确实有所帮助，但是在制作条形图时我一直在努力.所以下面是我的代码

I have seen many questions on changing the tick frequency on SO, and that did help when I am building a line chart, but I have been struggling when its a bar chart. So below are my codes

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame(np.random.randint(1,10,(90,1)),columns=['Values'])
df.plot(kind='bar')
plt.show()

这就是我看到的输出.如何更改滴答频率?

and thats the output I see. How do I change the tick frequency ?

(要在x轴上更清楚地显示5的频率！)

(To be more clearer frequency of 5 on x axis!)

推荐答案

使用 Pandas 绘图功能可以做到:

Using Pandas plot function you can do:

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.randint(1,10,(90,1)),columns=['Values'])
df.plot(kind='bar', xticks=np.arange(0,90,5))

或更佳:

df.plot(kind='bar', xticks=list(df.index[0::5]))
