如何在条形图的条形图内显示值? [英] How to show values inside the bars of a bargraph?

问题描述

我有一个像这样的数据框:

I have a dataframe like this:

                 platform     count
release_year        
         1996    PlayStation   138
         1997    PlayStation   170
         1998    PlayStation   155
         1999    PC            243...

现在，我想在各个条形图中绘制带有平台名称的水平条形图，使其看起来像这样:

Now I want to plot horizontal bargraph with the Platform name inside the respective bars such that it looks something like this:

我该怎么做?

推荐答案

找到每个平台中的百分比后，这就是输入的data.csv文件:

Here's the input data.csv file once you find the percentage in each platform:

Platform,Percent
Nintendo,34
PC,16
Playstation,28
Xbox,22

这是代码:

import pandas as pd
import matplotlib.pyplot as plt

df = pd.read_csv("data.csv", index_col=0)
df.plot(kind="barh", legend=False, width=0.8)
for i, (p, pr) in enumerate(zip(df.index, df["Percent"])):
    plt.text(s=p, x=1, y=i, color="w", verticalalignment="center", size=18)
    plt.text(s=str(pr)+"%", x=pr-5, y=i, color="w",
             verticalalignment="center", horizontalalignment="left", size=18)
plt.axis("off")
# xticks & yticks have empty lists to reduce white space in plot
plt.xticks([])
plt.yticks([])
plt.tight_layout()
plt.savefig("data.png")
