canvas.draw() is slow in animation, I have succeed in replacing it with

Thanks for your help. I get it work. However, an interesting thing appears.

I work matplotlib on wxpython, python2.5.
It is wonderful that the following code work faster than canvas.draw().
canvas.restore_region(background)
##Updata three lines and draw it.

Thanks for Eric Firing's reply to me.The solution is:
colorbar(im, extend='both', shrink=0.8,format='%0.1f%%',ticks=locator)
The double % in the format string makes it print a single %, and when
given a format string, the format kwarg automatically hands it off to a
FormatStrFormatter.

canvas.blit(ax.bbox)
canvas.gui_repaint()
