Render

This is done through rendering the figure first and then reload it in a FuncAnimation with imshow. Therefore the zoom function is limited to the resolution of the figure.

from smpl import animation
from smpl import plot
import matplotlib.pyplot as plt
import numpy as np
import tqdm

live-render

%matplotlib notebook
plt.ioff()
def update(a):
    plot.function(lambda x : a*x**2,xmin=0,xmax=5,init=True,tight=False)

ani = animation.animate(update = update,frames=np.linspace(0,10,200), interval=10,blit=True)
plt.show()

pre-render

%matplotlib notebook
plt.ioff()
for a in tqdm.tqdm(np.linspace(0,10,200)):
    plot.function(lambda x : a*x**2,xmin=0,xmax=5,init=True,tight=False)
    animation.frame()

#ani.save("test.gif")
ani = animation.animate(interval=10,blit=True)
plt.show()

To prevent deletion, assign the Animation to a variable, e.g. `anim`, that exists until you have outputted the Animation using `plt.show()` or `anim.save()`.
