问题描述

我在matplotlib(时间序列数据)中创建了一个图，该图上是一系列

I have a figure created in matplotlib (time-series data) over which are a series of

matplotlib.pyplot.axvline

行.我想在绘图上创建标签(这些标签可能靠近这些垂直线)(可能在该线的RHS上并朝该图的顶部).

lines. I would like to create labels on the plot that appear close to (probably on the RHS of the line and towards the top of the figure) these vertical lines.

推荐答案

您可以使用

plt.axvline(10)
plt.text(10.1,0,'blah',rotation=90)

您可能需要使用text中的x和y值来使其正确对齐. 您可以在此处找到完整的文档.

you might have to play around with the x and y value in text to get it to align properly. You can find the more complete documentation here.
