I would probably do it like this:

;----------------------------------------------------------- ---
X=[2, 4, 5, 6, 7, 8]
Y=[20, 40, 45, 30, 10, 5]
I=[100,200,300,400,500,600]

;intensity color
colors = cgScaleVector(Findgen(N_Elements(I)), Min(I), Max(I))
clr = Value_Locate(colors, I)
clr = Byte(Round(cgScaleVector(clr, 0, 255)))
TVLCT, r, g, b, /Get
TVLCT, r[clr], g[clr], b[clr], 1
TVLCT, r, g, b, /Get

cgWindow, 'TVLCT', r, g, b

;the scatterplot
cgPlot, X, Y, /Nodata, /AddCMD, Position=[0.125, 0.125, 0.9, 0.8]
FOR j=0,N_Elements(X)-2 DO cgPlotS, [X[j], X[j+1]], [Y[j], Y[j+1]], $
Color=clr[j+1], Psym=16,symsize=2,/AddCMD
FOR j=0,N_Elements(pNPP)-1,2 DO cgPlotS, X[j], Y[j], $
Color=clr[j+1], Psym=16,symsize=2, /AddCMD

cgDCBar, NColors=N_Elements(clr), Bottom=1, /AddCmd
END
;----------------------------------------------------------- ---

Cheers,

David
