How to curve text in a polar plot in matplotlib?

To curve text in a polar plot in matplotlib we can take the following steps

Steps

Set the figure size and adjust the padding between and around the subplots.
Create a new figure or activate an existing figure.
Add an 'ax' to the figure as part of a subplot arrangement.
Plot the line with some degree, color='green' and linewidth=2.
Create x and y data points, with some curve and plot them using plot() method.
To display the figure, use Show() method.

Example

from matplotlib import pyplot as plt
from scipy.interpolate import interp1d
import numpy as np

plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True

fig = plt.figure()
ax = fig.add_subplot(111, projection="polar")

for degree in [0, 90, 360]:
   rad = np.deg2rad(degree)
   ax.plot([rad, rad], [0, 1], color="green", linewidth=2)

for curve in [[[0, 90], [0.45, 0.75]]]:
   curve[0] = np.deg2rad(curve[0])
   x = np.linspace(curve[0][0], curve[0][1], 500)
   y = interp1d(curve[0], curve[1])(x)
   ax.plot(x, y, lw=7, color='red')

plt.show()

Output

It will produce the following output −
