In 3D computer graphics, a voxel represents a value on a regular grid in three-dimensional space. We can say a voxel is a 3D equivalent of a pixel that is used in 2D. A pixel is a square inside of a 2D image with a position in a 2D grid and a single color value, whereas a voxel is a cube inside of a 3D model with a position inside a 3D grid and a single color value.To represent voxels with matplotlib, we can take the following steps −StepsSet the figure size and adjust the padding between and around the ...

To avoid line color repetition in matplotlib.pyplot we can take the following steps −StepsSet the figure size and adjust the padding between and around the subplots.Create x and y data points using numpy.Plot the x and y data points using plot() method.In the plot() method, use a unique hexadecimal value for the color attribure, for example, color="#980ab5" to set the graph in a unique color. You can also specify a particular color of your choice, for example, color="green".To display the figure, use show() method.Exampleimport numpy as np from matplotlib import pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] ...
