[Matplotlib-users] another question for colorbar

[Humufr <hu...@ya...>]

I have this script:

from pylab import *
from numarray import *

a = arange(10)

scatter(a,a,c=a,s=60,cmap=cm.winter)
colorbar()
show()

but instead to have the brighter point in green I want to have them in 
blue. To obtain it I did a stupid things and I invert the map:

from pylab import *
from numarray import *

a = arange(10)

scatter(a,a,c=-a,s=60,cmap=cm.winter)
colorbar()
show()

but the colormap scale is in good direction green to blue but negative. 
Do you know how can I correct this perhaps it's not possible and the 
anly way to do this is to create a new color map?

Thanks,

N.
