Dear NCL users,

I use gsn_define_colormap(wks,"BlueWhiteOrangeRed") to generate a map, the colorbar value range from -2 ~ +1.25, but the position of 0 value is not in the middle of the bar. Is there any method to have a symetrical color bar centered with 0 value, and negative vale to its left, positive value to the right.
