matplotlib: Can I interrupt an `axhline` with text?

Question

In a plot, I would like to draw an axhline in a particular plot which is annotated by its value, a bit like the contour plot example here. E.g. looking something like: --------- 0.13 -----------.

Is this possible in matplotlib?

Answer 1

You can create a normal text object at the center point of the line and then set the background color to the color of the axes so that the horizontal line is not visible behind the text.

plt.axhline(linewidth=4, y=0.5, color='red')

plt.text(0.5, 0.5, 'text', fontsize=30, va='center', ha='center', backgroundcolor='w')
