如何在Matplotlib中的堆叠水平条形图中显示数据值 [英] How to display data values in stacked horizontal bar chart in Matplotlib

问题描述

您好，我目前正在使用数据框绘制堆叠的水平条形图。代码如下

  new_data.plot.barh（stacked = True）
  

我得到如下图。

理想情况下，我想在其中显示数据值，如下所示。

我该如何实现？任何帮助表示赞赏。谢谢

还有一个类似的问题

Hi I am currently plotting stacked horizontal bar chart using dataframe. The code is as below

new_data.plot.barh(stacked = True)

I get a chart like below.

Ideally I would want to have the data values displayed inside it, like below.

How do I accomplish this? Any help is appreciated. Thanks

解决方案

there's a similar question here, just use ax.text and adjust the x and y positioning according to your bar value and bar enumeration, for example:

import pandas as pd
df = pd.DataFrame({'value1':[10, 30, 20],'value2':[20,50,10]})
ax = df.plot.barh(stacked = True);
print(df)
for rowNum,row in df.iterrows():
    xpos = 0
    for val in row:
        xpos += val
        ax.text(xpos + 1, rowNum-0.05, str(val), color='black')
    xpos = 0
display(ax)
