I've created my maps using shape files of the UK at a postcode area level. My proc map import data set has:
X Y Postcode-area
-2 56 AB
-2 52 B
-2 53 BB
My response variable is called response from the response_1 dataset
proc gmap map=Post code areas data=response_1;
id Postcode-area;
choro response / ;
run;
quit;
I'm trying to annotate each area with the appropriate postcode-area.
All the examples I've come across use %annomac; %centroid, however I can't get it to work for my maps.
Any help will be much appreciated.
Thanks
Here's a simple example that shows the basics:
data my_map; set maps.us;
original_order+1;
run;
proc sort data=my_map out=my_map;
by statecode;
run;
%annomac;
%centroid(my_map, centers, statecode, segonly=1);
data centers; set centers;
xsys='2'; ysys='2'; hsys='3'; when='a';
length function $50;
function='label';
text=trim(left(statecode));
run;
pattern1 v=s c=cornsilk;
proc gmap data=my_map map=my_map anno=centers;
id statecode;
choro segment / levels=1 nolegend;
run;
