Legend

This is an example of using pplt.legend.

Note

If you want to disable the border for the default style you can simply rely on the matplotlib parameter and pass frameon = False to the method, for more parameters check out matplotlib.pyplot.legend.

import numpy as np
import prettypyplot as pplt
from matplotlib import pyplot as plt

# define random data to plot
np.random.seed(1337)
N = 500
T = np.linspace(0, 3 * np.pi, N)
X1, X2 = [
    np.sin(T + np.pi * np.random.rand()) + 0.1 * np.random.rand(N)
    for _ in range(2)
]

# loop over  random data to plot
for style in ['default', 'minimal']:
    pplt.use_style(style=style, figsize=1.2)

    fig, axs = plt.subplots(1, 3, gridspec_kw={'wspace': 0.25})

    # legend
    for i, outside in enumerate(['top', False, 'right']):
        ax = axs.flatten()[i]
        pplt.plot(T, X1, ax=ax, label='$x_1$')
        pplt.plot(T, X2, ax=ax, label='$x_2$')

        pplt.legend(title='title', ax=ax, outside=outside)

    pplt.savefig(f'images/legend_{style}.svg')
