[Matplotlib-users] Question to scatter plot

Hi,

I have problems with plotting in matplotlib. I want to plot something and
then overlay this plot with a scatter plot, so like this:

clf()
plot( sx, sy, 'kx')
hold(True)
scatter( ix, iy, 40, c=iz, faceted=False)
colorbar()
hold(False)

Although the scatter command is called later, any point drawn with the "
scatter"-command lies behind the black crosses drawn by the "plot" command.
Any ideas how to get the order right?

Cheers
  Alex
