I am using this macrotised code:

 

%macro PlotMacro(Title, Footnote, X, Y, Z);
	title &Title.;
	proc sgplot data=SomeData 
		noautolegend;
	  bubble X = &X. Y = &Y. size= &Z. /  
	    transparency=0.4 datalabelattrs=(size=9 weight=bold);
	run;
%mend;

Is there a way to color the bubbles according to a 'group/class' column in SomeData.

Use the GROUP= option in the bubble statement after the / as in this very simple example

 

title "Bubble plot by Sex";
proc sgplot data=sashelp.class noautolegend;
  bubble x=height y=weight size=age / group=sex;
run;

 

Also, why do you use a macro to do this? It just seems like more typing to me.

Hi,

 

There is a group option in the Bubble statement. I believe you can use that to color the bubbles, i.e. group=column (in Somedata)

 

Many thanks,

The bubble plot supports the group option which will color the bubbles based on a character variable.  It also supports the color response option which will color the bubbles based on a numeric variable.

Thanks. I just noticed this. I use ... /group = Bla. Any idea how I can add a legend based on Bla?

Something like in this example?

 

title "Bubble plot by Sex";
proc sgplot data=sashelp.class noautolegend;
  bubble x=height y=weight size=age / group=sex;
  keylegend / position=nw location=inside across=1;
run;

The sgplot procedure will automatically create a legend based on the group variable.  Remove the no auto legend from your program, and you should then see the legend. 

Thanks

Just noticed that I had noautolegend - removing that shows the legend.
