colored vector plots [message #87861]

Dear all,
What is the most efficient way to do colored vector plots (representing colors corresponding to their magnitude). I currently use 'msvelovect.pro' to plot vectors on map projections, but i can not seem to color them.
Currently i just say msvelovect,u,v,lon,lat,colors=?!?something
I guess there is not much color option in this one, so I tried partvelvec.pro, but i could not succeed there either. I defined my lon, lat,u and v are the same size = (76,51). I tried to scale_vector and cgscalevector as:
colors=cgscalevector((indgen(n_elements(u(0:75,0:50)))),0,25 5)
and then partvelvec,u,v,lat,lon,veccolors=colors, but it gives errors such as:
CGDEFAULTCOLOR: Cannot determine a color from a value of 0.131613 of data
% CGDEFAULTCOLOR: Cannot determine a color from a value of 0.197419 of data

Could anyone please suggest a solution?
Thanks in advance,
Anil
