How to use 2D histograms to plot the same PDF; Let’s start by generating an input dataset consisting of 3 blobs: import numpy as np import matplotlib.pyplot as plt import scipy.stats as st from sklearn.datasets.samples_generator import make_blobs n_components = 3 X, truth = make_blobs(n_samples=300, centers=n_components, cluster_std = [2, 1.5, 1], random_state=42) … It allows you to generate high quality line plots, scatter plots, histograms, bar charts, and much more. pi) / 2 + 0.5 ax. Also, a 2D plot is used to show the relationships between a single pair of axes that is x and y whereas the 3D plot, on the other hand, allows us to explore relationships of 3 pairs of axes that is x-y, x-z, and y-z. the function flux_qubit_potential you show).
