How can I get the position of the value 0 in cnLevels while setting the
resources for contour plot ?
My requirement is as follows.
I would like to get *white to represent the value near to zero* in
contour interval irrespective of the data range.

gsn_define_colormap(wkspnl,"ViBlGrWhYeOrRe")
white = 52
data_min = min(data)
data_max = max(data)
if (data_min .gt. 0) resc@gsnSpreadColorStart = white
resc@cnLevelSelectionMode = "ManualLevels" resc@cnMinLevelValF = 0 end if if
(data_max .lt. 0) resc@gsnSpreadColorEnd = white resc@cnLevelSelectionMode =
"ManualLevels" resc@cnMaxLevelValF = 0 end if
if ((data_min .lt. 0) .and. (data_max .gt. 0))
*----------*
*???????*
*----------* end if
----------------------

How can I implement this?
