Proc SGMAP - Can't limit bubble size in map bubble plot

cookan — Wed, 06 Nov 2019 18:31:33 GMT

I'm using proc sgmap to make a bubble plot of walleye catches in Lake Erie. I would like to reduce the maximum size of the bubbles to fit the map better. The BRADIUSMAX option doesn't seem to work (as it does in proc sgplot).

*variable "wall" is the catch of walleye in index nets;

*second set of coordinates plot zero catches - catches greater than zero have missing coordinates;

goptions reset=all;

ODS PDF FILE='Erie_Map_wal2019.pdf' NOTOC;

title 'Walleye Catch 2019';

proc sgmap mapdata=Erie plotdata=map1;

choromap / mapid=ID density=6 ;

bubble X=X Y=Y size=wall / NOFILL BRADIUSMAX=20;

scatter X=X2 Y=Y2 / markerattrs=(color=red size=6 symbol=circlefilled) ;

run;

ODS PDF CLOSE;

title;

Any help would be appreciated.

Did you also use the BRADIUSMIN in conjuction with the BRADIUSMAX?

It also looks like you need to specify the dimension value. Below is taken from here: https://documentation.sas.com/?docsetId=grmapref&docsetTarget=p1nywdk7q1c0esn1myhukeensapm.htm&docsetVersion=9.4_01&locale=en

SAS 9.4M6 BRADIUSMAX=n<units>

specifies the size of the radius of the largest bubble. You can specify any positive number for n, including decimals, as the dimension of the size.

If you want to specify a dimension in a unit other than the default, then you must specify the desired unit with the dimension value. An example is BRADIUSMAX=5PX. For a list of measurement units that are supported, see Units of Measurement in SAS ODS Graphics: Procedures Guide. Viable units of measure are CM, IN, MM, PCT or %, PT, or PX.

I added BRADIUSMIN and px units without success. The log message is:

ERROR 22-322: Syntax error, expecting one of the following: ;, DATALABEL, DATALABELATTRS,

DATALABELPOS, FILL, FILLATTRS, LEGENDLABEL, NAME, NOFILL, OUTLINE, TRANSPARENCY.

ERROR 76-322: Syntax error, statement will be ignored.

Thanks for the suggestion though.

What version of SAS are you running it seems like maybe your not on 9.4 M6?

9.4 TS level 1M5

x64 10pro

Not expected to work?

It looks like it was added with M6 version. Given the log doesn't mention it as it does with the other optional parameters I'm going to assume that's the reason why BRADIUSMAX is not working for you. I've never messed with a bubble plot or anything regarding ODS graphics so outside of upgrading to the M6 version I'm out of ideas unfortunately.

OK thanks. Appreciate your help.

Good luck, once you get it working I wouldn't mind seeing the output. I'm not much of a walleye fisherman (Bass for me) but something like this could come in handy on some of my local lakes before fishing tournaments.
