  3. Congressional Redistricting Data with PROC GSLIDE if first.segment then do row=line; line=1; xsys = "2"; ysys = "2"; function="poly"; when= 'A'; style="msolid"; output; end; else do row=line; function = "polycont"; when= 'A'; xsys = "2"; ysys = "2"; line = 1; style="msolid"; output; end; run; data annoplace; length function color $8; set city (keep=x y line type tlid placer segment); by placer segment;

  16. Glyph Map using PROC GMAP

  17. Glyph Map using PROC GMAP %macro shades(var=, lablvar=, data=, loshade=0, hishade=255, midval=xmax/2-xmin/2);

  18. Glyph Map using PROC GMAP Shade from red to yellow if &var < (&midval) then do; imval=int(.499999 + &loshade + (&var-xmin) * ( (&hishade-&loshade)/((&midval)-xmin) )); shade = 'CX' || 'FF' || put(imval, hex2.) || '00' ; end;

  19. Glyph Map using PROC GMAP Shade from yellow to green else do; imval=int(.499999 + &loshade + (&var-(&midval)) * ( (&hishade-&loshade)/(xmax-(&midval)) )); shade = 'CX' || put(&hishade - imval + &loshade,hex2.)|| 'FF' ||'00'; end;
