Re: curve colors

Will,

Thanks. In my case, the array of line colors is the NOT in same size.
The first one has 3, and second has 1 only. I tried something as below, but
the curve color from the array 2 follow the color for array 1, i.e. red.

 anything wrong?

 res@xyLineColors = (/"red","green","blue"/)
 plot = gsn_csm_xy(wks,x,y,res)

res@xyLineColor = "brown"
 plot2 = gsn_csm_xy(wks, x2,y2,res)
