23 Apr Create Markers in Matplotlib

In Matplotlib, markers are used to highlight individual data points on plots, making them easier to read and visually distinct. You can customize marker style, size, edge color, and face color using simple arguments in plt.plot() or plt.scatter().

To create a marker, use the marker parameter of the plt.plot(). Set the marker styles for the marker parameter, like:

marker='*'
marker='o'

Common Marker Styles

Example

Let us see an example to create markers in Matplotlib:

# Create Markers in Matplotlib with linestyle

import matplotlib.pyplot as plt
import numpy as np

ypts = np.array([7, 3, 9, 1, 5])

# plt.plot(ypts, marker='o', linestyle=':', color='red')
plt.plot(ypts, marker='*', linestyle='-', color='red')
plt.show()
