面积图X轴不显示

Question

我正在通过matplotlib创建面积图，并且未显示x轴标签（索引）。这是我的代码：

import pandas
import matplotlib.pyplot as plot

def graphing():


    data2 = [(12.20, 14.50, 15.60, 24.80),
         (11.30, 8.70, 23.20, 10.0),
         (6.40, 10.70, 22.60, 11.60),
         (15.0, 16.0, 23.40, 10.8)]

    columns = ["Expense Management", "Guidance", "Interest Rate and Deposit Costs", "Loan Growth"]

    index = ["2019Q3", "2019Q2", "2019Q1", "2018Q4"]

    df2 = pandas.DataFrame(data=data2, index=index, columns=columns)

    graph2 = df2.plot.area(stacked='True')

    graph2.axes.get_yaxis().set_visible(False)

    plot.show(block=True)


graphing()

我添加了诸如“ graph2.axes.get_xaxis（）。set_visible（True）”之类的行，它不会显示我的索引标签。对我该怎么办有什么想法？

Answer 1

您必须这样做：

graph2.axes.get_xaxis().set_visible(True)

评论后编辑： 抱歉，我无法重新创建您的问题。对我来说，以下代码可以正常工作：

import pandas
import matplotlib.pyplot as plot

def graphing():


    data2 = [(12.20, 14.50, 15.60, 24.80),
         (11.30, 8.70, 23.20, 10.0),
         (6.40, 10.70, 22.60, 11.60),
         (15.0, 16.0, 23.40, 10.8)]

    columns = ["Expense Management", "Guidance", "Interest Rate and Deposit Costs", "Loan Growth"]

    index = ["2019Q3", "2019Q2", "2019Q1", "2018Q4"]

    df2 = pandas.DataFrame(data=data2, index=index, columns=columns)

    graph2 = df2.plot.area(stacked='True')

    graph2.axes.get_yaxis().set_visible(False)
    graph2.axes.get_xaxis().set_visible(True)

    plot.show(block=True)
