What does a 4-element tuple argument for 'bbox_to_anchor' mean in Matplotlib?

If a 4-tuple or B box Base is given, then it specifies the b box (x, y, width, height) that the legend is placed in.

Steps

• Create x and y data points using numpy.
• Plot x and y using plot() method, with label y=sin(x) and color=green.
• To place the legend at a specific location, use location 'upper left' and use legend box dimension with four tuples that was defined in the above description.
• To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(-2, 2, 10)
y = np.sin(x)
plt.plot(x, y, c='green', label="y=sin(x)")
plt.legend(loc='upper left', bbox_to_anchor=(0.05, 0.75, 0.2, 0.2))
plt.show()
