Matplotlib animation

Question

I am trying to create an ABC logo and animate it with matplotlib, I have got all the phases by changing the delta index I am able to get all x and y coordinates but I am not able to animate from one phase to another .below is the link of what I am trying to do. https://www.youtube.com/watch?v=sL0FhqGtV4U&ab_channel=AustralianTelevisionArchive

import matplotlib.pyplot as plt import matplotlib.animation as animation import math import numpy as np from matplotlib.animation import FuncAnimation fig = plt.figure() axis = plt.axes(xlim =(-110, 110), ylim =(-110, 110)) delta = [0, 3.14 / 8, 3.14 / 4, 3 * 3.14 / 8, 3.14 / 2, 5 * 3.14 / 8, 3 * 3.14 / 8, 7 * 3.14 / 8, 3.14] def dS(delta): A = 100 B = 100 a = 1 b = 3 # delta = 3.14/4 t = 0 sinVals = [] cosVals = [] for i in range(0, 1000): t += 0.01 # Apply Lissajous Parametric Equations sinVals.append(A * math.sin(a * t + delta)) cosVals.append(B * math.sin(b * t)) return sinVals,cosVals sinVals,cosVals=deltaShift.dS(delta[1]) line, = axis.plot(sinVals, cosVals) plt.show()

This will produce what you want

import matplotlib.pyplot as plt import matplotlib.animation as animation import numpy as np from matplotlib.animation import FuncAnimation pi = np.pi deltas = np.linspace(0,8,32) / pi def dS(delta): A = 100 B = 100 a = 1 b = 3 # delta = 3.14/4 t = 0 sinVals = [] cosVals = [] for i in range(0, 1000): t += 0.01 # Apply Lissajous Parametric Equations sinVals.append(A * math.sin(a * t + delta)) cosVals.append(B * math.sin(b * t)) return sinVals,cosVals def make_plot(delta): ax.clear() ax.set_xlim(-110, 110) ax.set_ylim(-110, 110) sinVals,cosVals=dS(delta) line, = ax.plot(sinVals, cosVals) fig,ax = plt.subplots() ani = animation.FuncAnimation(fig, make_plot, deltas, blit = False) ani.save('test.gif', writer='pillow', fps=16)

The output gif file is
