如何从图形对象向matplotlib图添加文本？

Question

My code contains the following lines:

from matplotlib.figure import Figure

figure = Figure(figsize=(10, 5), dpi=dpi)

How can I add text to this

Answer 1

Texts can be added from a axis object. So you may try this:

from matplotlib.figure import Figure
figure = Figure(figsize=(10, 5), dpi=dpi)
ax = figure.add_axes((0.05, 0.05, 0.9, 0.9))
ax.text(0.5, 0.5, 'Text', ha='center')
