How to Add Markers to a Graph Plot in Matplotlib with Python? Last Updated : 03 Oct, 2022 Comments Improve Suggest changes Like Article Like Report In this article, we will learn how to add markers to a Graph Plot in Matplotlib with Python. For that just see some concepts that we will use in our work. Graph Plot: A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.Markers: The markers are shown in graphs with different shapes and colors to modify the meaning of the graph.Example 1: Add Square Markers to a Graph Plot in Matplotlib Python3 # importing packages import matplotlib.pyplot as plt # plot with marker plt.plot([2, 8, 7, 4, 7, 6, 2, 5, 9], marker='D') plt.show() Output : Example 2: Add Triangle Markers to a Graph Plot in Matplotlib Python3 # importing packages import matplotlib.pyplot as plt # create data t = np.arange(0., 5., 0.2) # plot with marker plt.plot(t, t, 'r--', t, t**2, 'bs', t, t**3, 'g^') plt.show() Output : Example 3: Add Circle Markers to a Graph Plot in Matplotlib Python3 # importing packages import matplotlib.pyplot as plt import numpy as np # create data x_values = np.linspace(0, 10, 20) y_values = np.sin(x_values) markers = ['>', '+', '.', ',', 'o', 'v', 'x', 'X', 'D', '|'] # apply markers for i in range(20): plt.plot(x_values, y_values + i*0.2, markers[i % 10]) plt.show() Output : Comment More infoAdvertise with us Next Article How to Add Markers to a Graph Plot in Matplotlib with Python?

Changing transparency in Matplotlib plots enhances visual clarity, especially when data overlaps. Transparency is controlled using a value between 0 (fully transparent) and 1 (fully opaque). This setting can be applied to elements like lines, bars, scatter points and filled areas either during plot 3 min read How to Change Point to Comma in Matplotlib Graphics in Python We are given a Matplotlib Graph and our task is to change the point to a comma in Matplotlib Graphics such that there is only a comma in the whole graph instead of a point.
