Subject:      ggraph contral scale

Happy New Year SPSSxers!

I am converting some old igraph code to work with ggraph gpl. In igraph, I
was able to control the scale and axes lengths with the following for a
categorical color scatterplot:

igraph
/y=var(zcord) type=scale(min=60 max=110)
/x1=var(ycord) type=scale(min=50 max = 150)
/ylength = 2
/xlength = 4
/color = var(segno) type = categorical
/scatter.


In ggraph, I have been unable to figure out how to control the scales and
axes in this way. My current code for the ggraph statement is as follows.

GGRAPH
  /GRAPHDATASET NAME="graphdataset" VARIABLES=xcord ycord
segno[LEVEL=NOMINAL] MISSING=LISTWISE
    REPORTMISSING=NO
  /GRAPHSPEC SOURCE=INLINE.
BEGIN GPL
  SOURCE: s=userSource(id("graphdataset"))
  DATA: xcord=col(source(s), name("xcord"))
  DATA: ycord=col(source(s), name("ycord"))
  DATA: segno=col(source(s), name("segno"), unit.category())
  GUIDE: axis(dim(1), label("x coordinate"), delta(10))
  GUIDE: axis(dim(2), label("y coordinate"), delta(10))
  GUIDE: legend(aesthetic(aesthetic.color.exterior), label("segno"))
  ELEMENT: point(position(xcord*ycord), color.exterior(segno))
END GPL.

Many thanks for your kind attention.

Best regards to you all.
