How to make hollow square marks with Matplotlib in Python?
To make hollow square marks with matplotlib, we can use marker 'ks', markerfacecolor='none', markersize=15, and markeredgecolor=red.
Steps
Creat x and y data points using numpy.
Create a figure or activate an existing figure, add an axes to the figure as part of a subplot arrangement.
Plot x and y data points using plot() method. To make hollow square marks, we can use marker "ks" and markerfacecolor="none", markersize="15" and markeredge color="red".
To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-2, 2, 10) y = np.sin(x) fig = plt.figure() ax1 = fig.add_subplot(111) ax1.plot(x, y, 'ks', markerfacecolor='none', ms=15, markeredgecolor='red') plt.show()
