Plotting color-coded coordinates in GMAP

[RandoDando]

I am trying to create individual state maps (starting with Maine) with color-coded points mapped out using X-Y coordinates.  The data set I am using for the points has X and Y coordinates, along with a specified color for the points to be used in the map.  This data set also has the same state code used in the map data set.  Below is my code.  I get no errors, but when I get to GMAP it only draws the state without the points from the anno set.  Any help would be appreciated.

data Maine;
   set mapsgfk.Us_states;
   if state =stfips("ME");
run;

data prop;   set ME_MFH2;
xsys='2'; ysys='2'; hsys='3'; when='a';
function='pie'; rotate=360; size=1.0;
style='psolid'; color=color; output;
run;

proc gproject data=prop
              degrees
              out=propg
              parmentry=mapsgfk.Us_states
              dupok;
   id;
run;


pattern value=mempty color=blue ;
proc gmap
data=maine map=maine  all
anno=propg ;
id state;
choro state /  nolegend;
run;
quit;

What version of SAS do you have?SGMAPs produces better quality graphics.

I'm using SAS EG 7.13, not sure which version of SAS is on the Metadata server.

this will tell you, check the log.

I would suggest that you examine the maximum and minimum values the X and Y variables of your Maine map data set and then separately the same for the annotate dataset Propg.

The parmentry data set you use in the Gproject, parmentry=mapsgfk.Us_states, will have a significantly different range of values than the Maine only set extracted from the US_states data set.

So I suspect that the annotate values may fall outside of Maine after projection. By any chance does you log show any message about such happening?

After some more searching I came across this, and the example seemed to work (all the prior examples I saw were doing things far more complex than what I needed).

Now, that I have the big part over with I am down to aesthetics.  The example used stars are the point symbols, but I prefer solid dots. 

Here is the original code copied from the link using stars:

data prop;   set ME_MFH2;
xsys='2'; ysys='2'; hsys='3'; when='a';
x= -x *(atan(1)/45);
y = y* (atan(1)/45);
function = 'label';
style    = 'special';
text     = 'M';     
color    = color ;              
size     = 2;                        
position = '5';                      
run;

 The TEXT = 'M' specifies stars with the style selected.  I've tried putting in 'U' for dots, but I get all sorts of strange symbols on my map.   Any idea on how to get the solid dots symbol to work?
