Sine wave

Example of how to use stream alongside a custom renderer to create a sine wave animation.

Highlights:

• Uses wrap_matplotlib to automatically handle saving and closing the figure.
• Uses a custom renderer function to create each frame of the animation.

import matplotlib.pyplot as plt
import numpy as np
from streamjoy import stream, wrap_matplotlib

@wrap_matplotlib()
def plot_frame(i):
    x = np.linspace(0, 2, 1000)
    y = np.sin(2 * np.pi * (x - 0.01 * i))
    fig, ax = plt.subplots()
    ax.plot(x, y)
    return fig

if __name__ == "__main__":
    stream(list(range(10)), uri="sine_wave.gif", renderer=plot_frame)
