[FIXED] Add text in a Matplotlib plot without y-coordinates

Issue

For a personal project, I'd like to add a text in the upper right corner of the plot but as I'm displaying horizontal bars, I don't have y-coordinates and thus, I can't use either plt.text()or ax.annotate()as they require a y-coordinates.

Here is a picture of the plot I'm having :

and here is what I would like to have (with text on the upper-left corner):

Solution

You can use text. And the coordinates "still exist". See the following example:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.subplots()
names = ["a", "b", "c"]
val = [23, 17, 5]
ax.barh(names, val)

ax.text(0.8, 0.95, "text 1", transform = ax.transAxes)
ax.text(20, 0, "text 2", transform = ax.transData)
ax.text(20, 2, "text 3", transform = ax.transData)

plt.show()

Resulting in:
