Thank Prof. Pisati  and Prof. Cox. I really appreciate for your reply and
very helpful suggestion.

Prof. Pisati, if I want to label two variables on the map, for example,  one
is region's name, another is region's GDP, is it possible? I tried to put
label(GDP) in label() option, the command was wrong. Could you please give
me some suggestion?  I appreciate. 

Best Regards,
Lynn Lee

Dear Lynn,
I apologize for not being more explicit. In my example x is just a dummy
variable, i.e., a variable I created to exemplify the procedure you were
looking for. In your case, x should be created by yourself according to your
needs, assigning value 0 to polygons you want to represent as "white", and
value 1 to those you want to represent as "green". For instance, suppose
your dataset includes 10 regions; regions 1, 3, 6, 8 are "white" (value 0),
while the remaining regions are "green" (value 1). To create the new
variable x, you might run the following command:

. generate x = 1 - inlist(id,1,3,6,8)

where -id- is an existing variable that uniquely identifies regions.
Best wishes,
Maurizio
