Subject:      question about ggraph/gpl
Content-Type: multipart/alternative;

Greetings,

I have a question about ggraph and gpl.  I am trying to make several
scatterplots (with a panel variable) using ggraph.  I have the code
mostly working, except that I can't get rid of the display of R-squareds
in the last panel.  In other words, it seems that by default, the
R-squareds for each fit line (one for each panel in the graph) are
displayed, and they are all displayed in the middle of the final panel
of the graph.  I would like to get rid the R-squareds, but I don't know
how to do this via the ggraph and/or gpl syntax.  The dataset and an
example of what I am trying to do can be found at
http://www.ats.ucla.edu/stat/spss/examples/alda/chapter4/aldaspssch4.htm
.

I didn't see any mention of display of R-squared values in the gpl
guide, much less how to control if or where they would appear.

Here is the syntax that I have been using:

formats alcuse age_14 (f3.0).
GGRAPH
  /GRAPHDATASET NAME="iGraphDataset" VARIABLES= alcuse age_14 id 
  /GRAPHSPEC SOURCE=INLINE 
      INLINETEMPLATE=["<addFitLine  type='linear' /> "
"<setWrapPanels/>"].
BEGIN GPL
SOURCE: s=userSource( id( "iGraphDataset" ) )
DATA: Y_Var=col( source(s), name( "alcuse" ) )
DATA: X1_Var=col( source(s), name( "age_14" ) )
DATA: Panel_Var0=col( source(s), name( "id" ), unit.category() )
COORD: rect( dim( 1, 2 ) )
GUIDE: axis( dim( 1 ), label( "age" ) )
GUIDE: axis( dim( 2 ), label( "alcuse" ) )
GUIDE: axis( dim( 3 ), label( "id" ), opposite() )
SCALE: linear( dim( 1 ) )
SCALE: linear( dim( 2 ) )
SCALE: cat( dim( 3 ) )
ELEMENT: point( position( ( X1_Var * Y_Var * Panel_Var0 * 1  ) ) )
END GPL.

Any suggestions would be appreciated.

Best,
