To fill a region with only hatch (no background color) in matplotlib, we can take the following steps −
Steps
Set the figure size and adjust the padding between and around the subplots.
Initialize a variable n to store the number of sample data.
Create a figure and a set of subplots.
Plot the x and y data points.
Fill the area between x and y with circle hatches, edgecolor="blue".
To display the figure, use show() method.
Example
import numpy as np import matplotlib.pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True # Number of sample data n = 256 # x and y data points x = np.linspace(-np.pi, np.pi, n, endpoint=True) y = np.sin(2 * x) # Figure and set of subplots fig, ax = plt.subplots() # Plot the data points ax.plot(x, y, color='blue', alpha=1.0) # Fill the area between the data points ax.fill_between(x, y, color='blue', alpha=.2, facecolor="none", hatch="o", edgecolor="blue", linewidth=1.0) # Display the plot plt.show()
