Plot n animated growing line plots on the same graph (matplotlib, python)

Question

I am trying to plot multiple animated line plots on the same graph with a delay of 1 second between each line plot in matplotlib python.

My previous question: How to create a delay between mutiple animations on the same graph (matplotlib, python)

I have a list of lists: [[10,20,30],[40,50,60],[2,3,5],[200,300,500]]

I want to plot each element of the list of list as animated line plot on the same graph. Animation should plot the 1st list , and then plot the second list, then the third list and then the fourth list. They shouldn't be plotted simultaneously.

Thanks

You can make use of matplotlibs interactive mode as shown here:

import pandas as pd
import matplotlib.pyplot as plt


fig, ax = plt.subplots()

plt.ion()   # set interactive mode
plt.show()
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)))
y_z=[y,z]
ax.set_xlim(x[0],x[-1])
ax.set_ylim(min(y[0],z[0]),max(y[-1],z[-1]))

color=['green','red']

k=0
for i in y_z:
    for j in range(len(i)):
        line, = ax.plot(x[:j],i[:j],color=color[k])
        plt.gcf().canvas.draw()
        plt.pause(0.1)
    k=k+1

Please check the image I have added, The plot should be animation, as in it should pass through the points

Thankyou . I am trying to have a continuous connected line plot

Thank you. I tried the edit. I still do not get the continuous plot as the figure you have uploaded

I copy pasted the code. But I still get points of "*"
