Creating labels where line appears in matplotlib figure

Question

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

matplotlib.pyplot.axvline

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.

Answer 1

You can use something like

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

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.
