How to draw a filled arc in Matplotlib?

To draw a filled arc in matplotlib, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.

• Create a figure and a set of subplots.

• Initialize two variables, r, yoff.

• Create x and y data points using Numpy.

• Fill the area between x and y plots.

• Set the axis aspect and draw the figure canvas.

• To display the figure, use show() method.

Example

import matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fg, ax = plt.subplots(1, 1) r = 2. yoff = -1 x = np.arange(-1., 1.05, 0.05) y = np.sqrt(r - x ** 2) + yoff ax.fill_between(x, y, 0) ax.axis([-2, 2, -2, 2]) ax.set_aspect("equal") fg.canvas.draw() plt.show()
