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
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.
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 = np.deg2rad(curve) x = np.linspace(curve, curve, 500) y = interp1d(curve, curve)(x) ax.plot(x, y, lw=7, color='red') plt.show()
