Hi, I'm stacked again, sorry, but I couldn't find any pointers with my google.
In my filled contour animation I thought to use colorbar instead complicating
with contour labeling, which just makes animation too full. So after reading
the docs, I used something like this simplified code:
==================================================
import numpy as np
import matplotlib.pyplot as plt
from matplotlib import animation
def init():
return ax.cla(),
def animate(i):
global t
r = np.random.random(10)
c = np.sin(2 * np.pi * r) * np.vstack(np.cos(2 * np.pi * r))
ax.cla()
cax = ax.contourf(c)
cbar = fig.colorbar(cax, ticks=[0, .3, .6, 1])
cbar.ax.set_yticklabels(['a', 'b', 'c', 'd'])
return ax,
if __name__ == '__main__':
fig = plt.figure()
ax = fig.add_subplot(111)
anim = animation.FuncAnimation(fig, animate, init_func=init,
frames=100,
interval=15,
blit=True)
anim.save('test.mp4', fps=15, extra_args=['-vcodec', 'libx264'])
==================================================
and noticed that colorbar object is not cleared from the scene, but it
repeatedly fills the plot until there are only colorbars on it. Here is sample
frame:

And I have no idea how to clean it. Can anyone tell me how to clean this
colorbar while iterating animation?
Thanks
