How To Create A Delay Between Mutiple Animations On The Same Graph (matplotlib, Python)

This is a reference from a previous question two lines matplotib animation import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation x = np.arang

Solution 1:

You could make the number of steps twice as long, first draw the first curve and then the other one.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

x = np.arange(130, 190, 1)
y = 97.928 * np.exp(- np.exp(-  0.1416 * (x - 146.1)))
z = 96.9684 * np.exp(- np.exp(-0.1530 * (x - 144.4)))

fig, ax = plt.subplots()
line1, = ax.plot(x, y, color="r")
line2, = ax.plot(x, z, color="g")

def update(num, x, y, z, line1, line2):
    if num < len(x):
        line1.set_data(x[:num], y[:num])
        line2.set_data([], [])
    else:
        line2.set_data(x[:num - len(x)], z[:num - len(x)])
    return [line1, line2]

ani = animation.FuncAnimation(fig, update, 2 * len(x), fargs=[x, y, z, line1, line2],
                              interval=295, blit=True)

ax.set_xlabel('Age (day)')
ax.set_ylabel('EO (%)')
plt.show()
