TEMPLATE: how to combine the equivalent of LAYOUT LATTICE and LAYOUT DATAPANEL

[lvm]

I have an interesting challenge with TEMPLATE.  I am trying to create a lattice where each plot within the lattice is a panel of graphs. For a single panel of graphs, I can easily do this with SGPANEL, but I need to make a single figure with several different panels. The following TEMPLATE code works just fine to create a 1x4 panel of graphs (instead of using SGPANEL):

proc template; 

 define statgraph test12;

 begingraph;

layout datapanel classvars=(type _trt) / rows=1 columns=4;

        layout prototype;

        bandplot x=year limitupper=uclmarg limitlower=lclmarg ;    

       seriesplot x=year y=y / lineattrs=graphFit ;

       scatterplot x=year y=y / markerattrs=(size=8px color=blue symbol=circlefilled) ;

    endlayout;    

endlayout;

endgraph;

end;

run;

I would like to wrap the equivalent of a "LAYOUT LATTICE" around this to have several rows, where each row is a panel of four (or whatever) graphs (with a different response variable for each row). I realize that LAYOUT LATTICE does not allow for DATAPANEL, so I am looking for a workaround. For instance, I would like to use something like:

proc template; 

 define statgraph test12;

 begingraph;

layout lattice / columns=1 rows=3;

   layout datapanel classvars=(type _trt) / rows=1 columns=4;

        layout prototype;

        bandplot x=year limitupper=uclmarg limitlower=lclmarg ;    

       seriesplot x=year y=p / lineattrs=graphFit ;

       scatterplot x=year y=y / markerattrs=(size=8px color=blue symbol=circlefilled) ;

     endlayout;

   layout datapanel classvars=(type _trt) / rows=1 columns=4;

        layout prototype;

        bandplot x=year limitupper=uclmarg2 limitlower=lclmarg2 ;    

       seriesplot x=year y=p2 / lineattrs=graphFit ;

       scatterplot x=year y=y2 / markerattrs=(size=8px color=blue symbol=circlefilled) ;

    endlayout;

 endlayout;

....

endlayout;

endgraph;

end;

run;

Any recommendations on how to do this? Thanks.

@lvm ,
You could try other way to workaround.

Thanks for the very helpful workaround!
