Re: Shade/Levels

[Ansley Manke <ansley@xxxxxxxxxxxxx>]

Hi Steve,
It looks to me as if you just have an extra end-of-line or a
space in your script, on the "define symbol d1"  command, so the
second grouping is not seen as part of the LEVELS specification

define symbol d1=levels=(-0.00002,-0.000001,0.000002)
(0.000001,0.00002,0.000002)

should have no space or line feed between the sets of parentheses.
It helps to group the different levels specs in quotes for clarity:

define symbol d1=levels="(-0.00002,-0.000001,0.000002)(0.000001,0.00002,0.000002)"

Good luck - Ansley
