constructing a legend for coloured circle scatter

I could guess at what you are trying to do, but it would help a lot if you posted an example that we could run, with comments about what you want to happen versus what is happening.

thanks... attached is an image of roughly what i want. a program is below.

from pylab import *
def xycs():
  print zip(c,s)
  setp(p, 'alpha', 0.75)
  return 0
if __name__=='__main__':
