如何在 Python Seaborn 的线图中的每个标记上添加值/标签?

How to add values/ labels over each marker in lineplot in Python Seaborn?

我有一个数据框,其中包含时间范围、股票和文本计数作为列。数据框看起来像这样

              Time Stock  Text
0   00:00 - 01:00  BBNI   371
1   00:00 - 01:00  BBRI   675
2   00:00 - 01:00  BBTN   136
3   00:00 - 01:00  BMRI   860
4   01:00 - 02:00  BBNI   936
5   01:00 - 02:00  BBRI  1325
6   01:00 - 02:00  BBTN   316
7   01:00 - 02:00  BMRI  1630

我想用下面的代码画一个线图:

df=tweetdatacom.groupby(["Time","Stock"])[["Text"]].count().reset_index()
plt.figure(figsize=(10,5))
line=sn.lineplot(x="Time", y="Text",hue="Stock",palette=["green","orange","red","blue"],marker="o",data=df)
plt.xticks(size=5,rotation=45, horizontalalignment='right',fontweight='light',fontsize='large')
plt.xlabel('Time Interval',size=12)
plt.ylabel('Total Tweets',size=12)

这是我用代码得到的结果:

现在,我想将每个标记的值放在图上,我该怎么做?

非常感谢

ax.text循环遍历数据的数量。我只是用提供给我的数据创建这个,所以我省略了你的一些处理。

for item, color in zip(df.groupby('Stock'),palette):
    for x,y,m in item[1][['Time','Text','Text']].values:
#         print(x,y,m)
        plt.text(x,y,m,color=color)
