A graph generated from the GRAPH command contains X and Y labels. Here is a method that can remove the X and Y label elements in SVG:

// -------------------------------------------------------------------
// Name: GRAPH_REMOVE_LABELS
// Description: Takes in a picture that is SVG format and removes the
// x-label and y-label.
// Parameter:
// $1 (PICTURE) - Graph picture variable to import.
// Output:
// $0 (PICTURE) - Picture that has the labels removed.
// -------------------------------------------------------------------
C_PICTURE($1;$input_picture)
C_PICTURE($0)

$input_picture:=$1

If (Count parameters>0)
   svg_id:=SVG_New
   svg_id:=SVG_Open_picture ($input_picture)

   $svg_ref:=SVG_Find_ID (svg_id;"ID_y_values")
   DOM REMOVE XML ELEMENT($svg_ref)

   $svg_ref:=SVG_Find_ID (svg_id;"ID_x_values")
   DOM REMOVE XML ELEMENT($svg_ref)

   SVG EXPORT TO PICTURE(svg_id;$0;Copy XML data source)

End if

Sample Graph with X and Y labels:

Sample Graph without X and Y labels:
