matplotlib-users Mailing List for matplotlib

Another observation/example. Depending on the order of the axes, the
last one is the only one that acts correctly. So I don't think it is
a coord issue.
-------------------------------------------------------------
import matplotlib
from pylab import *
ion()
axs =3D [subplot(221+i, xlim=3D(0,1), ylim=3D(0,1)) for i in xrange(4)]
canvas =3D gcf().canvas
draw()
bgs =3D [canvas.copy_from_bbox(ax.bbox) for ax in axs]
scats =3D [None for ax in axs]
def animate(event):
 global canvas, axs, bgs, scats
 order =3D [3,0,2,1]
 for i in xrange(150):
 print i
 x, y =3D rand(2,1)
 for i in order:
 if scats[i] in axs[i].collections: axs[i].collections.remove(scat=
s[i])
 for i in order:
 scats[i] =3D axs[i].scatter(x, y, animated=3DTrue)
 for i in order:
 canvas.restore_region(bgs[i])
 for i in order:
 axs[i].draw_artist(scats[i])
 for i in order:
 canvas.blit(axs[i].bbox)
canvas.mpl_connect('draw_event', animate)
show()
