How to plot gamma distribution with alpha and beta parameters in Python using Matplotlib?

To plot gamma distribution with alpha and beta parameters in Python, we can use gamma.pdf() function.

Steps

• Set the figure size and adjust the padding between and around the subplots.

• Create x using numpy and y using gamma.pdf() function at x of the given RV.

• Plot x and y data points using plot() method.

• Use legend() method to place the legend elements for the plot.

• To display the figure, use show() method.

Example

import numpy as np
import scipy.stats as stats
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

x = np.linspace(0, 10, 10)
y = stats.gamma.pdf(x, a=5, scale=0.333)

plt.plot(x, y, "ro-", label=(r'$\alpha=0, \beta=3$'))
plt.legend(loc='upper right')

plt.show()

Output
