How to make a histogram with bins of equal area in Matplotlib?
To make a histogram with bins of equal area in matplotlib, we can take the following steps −
Steps
Set the figure size and adjust the padding between and around the subplots.
Create random data points using numpy.
Plot a histogram with equal_area method that makes an equal area of the patches.
To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True def equal_area(x, nbin): pow = 0.5 dx = np.diff(np.sort(x)) tmp = np.cumsum(dx ** pow) tmp = np.pad(tmp, (1, 0), 'constant') return np.interp(np.linspace(0, tmp.max(), nbin + 1), tmp, np.sort(x)) x = np.random.randn(1000) n, bins, patches = plt.hist(x, equal_area(x, 20), edgecolor='black') plt.show()
Output
It will produce the following output −
