如何在 Pandas 数据框中的指定列上显示条形图?

在本文中,我们将了解如何在数据框中的指定列上显示条形图。为了完成这项任务,我们使用 Pandas Dataframe 的DataFrame.style.bar()方法。

现在,让我们创建一个数据框:

Python3
# importing required packages
import pandas
import numpy
  
Nan = numpy.nan
  
# creating a dataframe with some nan values
df = pandas.DataFrame(data = numpy.array(
                      [[9, -3.4, Nan, 9, Nan],
                       [9, 4.89, -3.4, Nan, 9],
                       [Nan, -3.4, Nan, 9, 56],
                       [4, -3.4, 59.0, 5.6, 90],
                       [-4, Nan, Nan, 34, 8.8]]),
                       columns = list("ABCDE"))
  
# view dataframe
df


Python3
# display the bar chart on dataframe
df.style.bar(subset = ['B', 'C'],
                   color = 'skyblue')


Python3
# display the bar chart on dataframe
df.style.bar(subset = ['A', 'D', 'E'],
                   color = 'yellow')


输出:

示例 1:

Python3

# display the bar chart on dataframe
df.style.bar(subset = ['B', 'C'],
                   color = 'skyblue')

输出:

示例 2:

Python3

# display the bar chart on dataframe
df.style.bar(subset = ['A', 'D', 'E'],
                   color = 'yellow')

输出:
