v1= 35.00 ; Low value for isopleths, disregarded when nv is 0 or 1 v2= 35.0875; High value for isopleths, disregarded when nv is 0 or 1 nv= 35 ; No. of isopleths, there will be nv+1 colors

;mapname=;"LR BkBlAqGrYeOrReViWh200"; rainbow style, nv <= 17 mapname="HR BkBlAqGrYeOrReViWh200"; rainbow style, nv <= 35
(In ncl, a semicolon [;] is the start of a comment field that extends to the end of the line.)

The figure below was made by issuing the same command as in Example 3, after the file userdef.ncl was copied from
