control marker size on spaghetti plots

[vstorme]

Dear all,

I have following code:

data myattrmap;
length linecolor $ 6 linepattern $ 5 markercolor $ 6 markersymbol $ 13;
input ID $ value $ linecolor $ linepattern $ markercolor $ markersymbol $;
datalines;
myid  young teal   solid teal    DiamondFilled
myid  old   purple solid purple  DiamondFilled
;
run;
proc print data = myattrmap;
run;

ods graphics/ reset=all width=16cm ;
title "Results &var by concentration and leaf stage";
Proc SGpanel data = &lib..rides_anno_flag noautolegend dattrmap = myattrmap;
  PanelBy treatment / columns=2;
  series x=date y=&var / group=uniqueID
                         grouplc=leaf lcattrid=myid /*lc line color*/
                         grouplp=leaf lpattrid=myid /*lc line pattern*/
                         groupmc=leaf mcattrid=myid /*lc marker color*/
                         groupms=leaf mcattrid=myid /*lc marker symbol*/
                         markerattrs=(size=10)
                         name='grouping'; 
  keylegend 'grouping' / type=linecolor;
  rowaxis display=(nolabel) grid;
  colaxis values=('11oct2023'd, '18oct2023'd, '25oct2023'd, '2nov2023'd)
          valuesformat = date7.;
  where flag = 0;
run;
title;

according to the SAS documentation, I should be able to control the marker size with markerattrs, but it does not seem to have an effect:

I am using sas-analytics-pro on SAS Studio (SAS Viya) version: V.04.00M0P031323

Can somebody clarify this?

Thanks, Veronique

Another option ... try GTL with PROC SGRENDER.

OK, I found it ...
You need

markers markerattrs=(size=10);  

instead of just

markerattrs=(size=10);

ah yes, that makes sense! I had it before and then removed it when adding groupmc and groupms.
