[gradsusr] hatching significance

[Alan Robock]

Hi,

I have made some global maps of observations and model results, and want 
to hatch the areas that are not significant.  I am using GrADS Version 
2.0.a3.  I have information on the significance levels.  My question is 
about the graphics.  How can I put hatching on top of the areas where 
the significance is above or below a particular value?  I see there is a 
set tile command in version 2.1.  Do I have to install that, or can I do 
it with the version I already have? Thanks.
