Colors in proc gmap

[Doris1]

Hi All,

I am brand new to PROC GMAP. I am using the following tutorial to practice:

http://www2.sas.com/proceedings/sugi29/251-29.pdf

I am stuck on example 5 using proc format to generate discrete areas on the map. I copied the provided code and ran in SAS 9.4, but it does not seem to provide colors. Even when I tried to use different colors (like red, green, gray, blue), the whole map has a single color (red). I don't know if I am doing anything wrong or if it is the version of the SAS I am using (9.4).

* example 5
* create a format to group observations (counties) based on the population;
proc format;
value pop2000_
5379 - 51134 = '5,379 - 51,134'
51401 - 91070 = '51,401 - 91,070'
93765 - 235469 = '93,765 - 235,469'
280150 - 2465326 = '280,150 - 2,465,326'
;
run;
* 2000 census population, New York State counties;
data nys2000;
input county pop2000 @@;

;
run;
* fill patterns for the map areas (gray-scale fills);
pattern1 v=s c=grayff;
pattern2 v=s c=grayda;
pattern3 v=s c=grayaa;
pattern4 v=s c=gray68;
proc gmap
data=nys2000
map=nys;
id county;
choro pop2000 / discrete;
format pop2000 pop2000_.;
note ' EXAMPLE #5'
j=l ' NEW YORK STATE'
j=l ' COUNTY POPULATION, 2000';
run;
quit;

I've also tried using the default settings, but it has not resolved the single-color map that SAS keeps generating. I am sure there is an easy solution...

I would appreciate your help.

Never mind! I was able to figure out...

The following code placed before proc gmap helped to yield the right map in a graph window.

goptions reset=all border;
