See if the density.kernel GPL function is available in Version 16. Here’s an example using it with the ozone sample file:
GET
FILE='C:\Program Files\IBM\SPSS\Statistics\19\Samples\English\ozone.sav'.
DATASET NAME DataSet1 WINDOW=FRONT.
GGRAPH
/GRAPHDATASET NAME="graphdataset" VARIABLES=ozon MISSING=LISTWISE REPORTMISSING=NO
/GRAPHSPEC SOURCE=INLINE.
BEGIN GPL
SOURCE: s=userSource(id("graphdataset"))
DATA: ozon=col(source(s), name("ozon"))
GUIDE: axis(dim(1), label("Daily ozone level"))
GUIDE: axis(dim(2), label("Frequency"))
ELEMENT: interval(position(summary.count(bin.rect(ozon))), shape.interior(shape.square))
ELEMENT: line(position(density.kernel.epanechnikov(ozon)))
END GPL.
