Hopefully this will be enough specifics,
since I can't attach the graphs themselves.
I generated the graphs with the chart
builder. The syntax is:
SORT CASES BY Compound.
SPLIT FILE LAYERED BY Compound.
* Chart Builder.
GGRAPH
/GRAPHDATASET NAME="graphdataset"
VARIABLES=SP_NS_B Area_ovr_Quin Chromatogram GC_NPD_source MISSING=LISTWISE
REPORTMISSING=NO
/GRAPHSPEC SOURCE=INLINE.
BEGIN GPL
SOURCE: s=userSource(id("graphdataset"))
DATA: SP_NS_B=col(source(s),
name("SP_NS_B"), unit.category())
DATA: Area_ovr_Quin=col(source(s),
name("Area_ovr_Quin"))
DATA: Chromatogram=col(source(s),
name("Chromatogram"), unit.category())
DATA: GC_NPD_source=col(source(s),
name("GC_NPD_source"), unit.category())
GUIDE: axis(dim(1), label("SP_NS_B"))
GUIDE: axis(dim(2), label("Area_ovr_Quin"))
GUIDE: axis(dim(3), label("GC_NPD_source"),
opposite())
SCALE: linear(dim(2), include(0))
ELEMENT: schema(position(bin.quantile.letter(SP_NS_B*Area_ovr_Quin*GC_NPD_source)),
label(Chromatogram))
So, the y axis is the area from the
chromatogram for the compound in question, divided by the area of the internal
reference standard, quinoline. That's the variable "Area_over_Quin",
continuous (scale). Each panel has 3 box-and-whisker elements, one
for blanks, one for smoking-permitted spaces, and one for non-smoking spaces
(variable "SP_NS_B", categorical). There is a separate
panel for each change of "source," i.e. the bead used in GC-NPD,
because they each perform differently. I want to put a line on each
panel corresponding to the calculated limit of detection for samples run
with that particular bead, for that particular compound. So it isn't
arbitrary. I have 11 compounds (split file by compounds) and
six sources. For each compound I have a six panel graph, and would
like to put a horizontal line at a different position on each of the six
panels.
It may not be possible. I'm just
hoping not to have to work with 66 separate graphs if I can.

Can you be more specific
about the chart—is the horizontal reference line arbitrary? Are the panels
determined by some categorical variable? Do you have the syntax that generated
the chart?

I have clustered boxplots with a column panel variable. I would like
to put a different horizontal reference line on each panel. Is there
a way to do this either when creating the graph or in the chart editor?
