You can make this a little bit more efficient.
import numpy as np
import bqplot.pyplot as plt
from ipywidgets import interact, FloatSlider
fig = plt.figure()
xs = np.linspace(-3,3,100)
lines = plt.plot(xs, [])
def freq(a):
lines.y = np.sin(a * xs)
demo = interact(freq, a=FloatSlider(value=1, min=-3, max=3, step=0.01))
plt.ylim(-1.1,1.1)
plt.show()
also, passing
animation_duration=300
to figure() enables smooth transitions between different positions of the
lines.
Cheers,
