Am trynig to draw a choropleth map for all states of us using zipcodes. 

Following is the error:

below is the code....

I don't understand your Proc GMAP.  You have "choro zip" but I don't see where you assigned "zip" to MAP. 

I put a data step above your code with the ZIP Code for SAS:

data allx;

Postal_Zip___Personal_Dta='27513'; output;

run;

And I changed the "choro state" and it produces a small dot in NC where that ZIP code is.

 

If yours is working and drawing the dots, it could be that you have ZIP Codes that are on the coast or on an island and the map isn't fine grained enough to show the exact coast line.  These will produce that message if it is slightly in the water.

 

You may want to make your dots bigger.  This macro will do that:

/*-----------------------------------------------------------*/
/* Macro to create point data in an annotate data set
 * annodata = point annotate data set created. 
 * inputdata = Input data set containing points to be drawn.
 *      Note that this data must contain variables x and y
 *      with the location of the points.
 * color = Graph color.  eg: red
 * size = dot size (optional).  Default is .7;
 * tipvar = Variable name to be used for tool tip (optional).
 * Note:  search for ????? for items that can be modified.
 */   
%macro make_dots(annodata, inputdata, color, size, tipvar);
data &annodata;
  length function color $ 8 style $20 position $ 1 text $ 60 html $1024;
  retain xsys ysys '2' hsys '3' when 'a' size .7;
  set &inputdata;
  /*optional arguments*/
  %if (&size ^= ) %then %do;
    size=&size;
  %end;
  /* All annotate points are 360-degree pies.  */
  function='pie';
  rotate=360;
  style='psolid';
  color=&color;

  /* optional tool tips */
  %if (&tipvar ^= ) %then %do;
    html= 'title=' || quote("&tipvar" ||'=' || trim(left(&tipvar)) );
  %end;
  output;
run;
%mend;

Hi,

Following is my data, and I want to draw a map for count of  stcnt at  zipcode level  for each statecode.

I have three variables Zip Stcnt Statecode.

data allx;
input zip statecode$ stcnt;

Please help.

I had to change your program around to make it work.  In ALLX. you did not have Postal_Zip___Personal_Dta listed.

data allx;

input Postal_Zip___Personal_Dta $ statecode$ stcnt;

length zip 5;

zip=Postal_Zip___Personal_Dta;

cards;

 

And in the GMAP, i had to change 'CHORO ZIP' to "CHORO STATE".  ZIP must be in the "MAP" data set. 

CHORO does not work with the ANNOTATE data set.

 

Finally, your messages are coming out because you have Puerto Rico (PR) in your ZIP Codes and you do not have it in your map.
