Hello everyone,

I want to get a jitter scatter plot on SPSS for two ordinal variables. I use the Graph Fonction and then I paste the syntax and add "jitter" where needed.

When I run the graph, I received this message : error # 99. Command name: BEGIN GPL >This command is only valid immediately following the GGRAPH procedure. >Execution of this command stops.

Here's my syntax:

DATASET ACTIVATE Dataset1.
    * Chart Builder.
GGRAPH
  /GRAPHDATASET NAME="graphdataset" VARIABLES=V1 V2 
    MISSING=LISTWISE REPORTMISSING=NO
  /GRAPHSPEC SOURCE=INLINE
  /FITLINE TOTAL=NO.
BEGIN GPL
  SOURCE: s=userSource(id("graphdataset"))
  DATA: V1=col(source(s), name("V1"), unit.category())
  DATA: V2=col(source(s), name("V2"), unit.category())
  GUIDE: axis(dim(1), label("V1"))
  GUIDE: axis(dim(2), label("V2"))
  SCALE: cat(dim(1), include("0.00", "1.00", "2.00", "3.00"))
  SCALE: cat(dim(2), include("0.00", "1.00"))
  ELEMENT: point.jitter(position(V1*V2))
END GPL.

I notice that /FITLINE TOTAL=NO. is not an actual fonction, but when adding a "s" to FITLINE, it turns green, "TOTAL" turns red and "No". Running the syntax after this change does not do anything and I receive the same error message...

I just don't get it.

If anyone have thoughts it would be great. Your help would be greatly appreciated!

Cheers

variable level v1 v2 (ordinal).

GGRAPH

 /GRAPHSPEC SOURCE=INLINE
 /FITLINE TOTAL=NO.
BEGIN GPL
 SOURCE: s=userSource(id("graphdataset"))

 DATA: V2=col(source(s), name("V2"), unit.category())
 GUIDE: axis(dim(1), label("V1"))
 GUIDE: axis(dim(2), label("V2"))
 SCALE: cat(dim(1), include("0.00", "1.00", "2.00", "3.00"))
 SCALE: cat(dim(2), include("0.00", "1.00"))
 ELEMENT: point.jitter(position(V1*V2))
END GPL.​

And for me, FITLINE is already green (meaning that it is recognized as a valid subcommand) without adding anything:

I am guessing that an invisible character is embedded in your syntax file somewhere inside the GGRAPH command. I don't know what else it could be.
