Hi,
I think you are safe just hard-coding your commands relative to
the documented default label sizes.
Another thing that's useful is a set of symbols that are defined
with each plot which contain some descriptions of labels, among
other things. These are listed here,
http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/customizing-plots/SPECIAL-SYMBOLS.
Look for the ones starting with LAB
yes? use levitus_climatology
yes? shade/z=5 salt
yes? sh symbol lab*
LAB1 = "FERRET (optimized) Ver.7.12"
LAB2 = "NOAA/PMEL TMAP"
LAB3 = "20-JUN-2017 15:56:59"
LABX = "LONGITUDE"
LABY = "LATITUDE"
LABTIT = "SALINITY (PPT)"
LAB4 = "DEPTH (m) : 0"
LABNUM_Z = "4"
LAB5 = "DATA SET: levitus_climatology"
LABNUM_DSET = "5"
LAB6 = ""
LABNUM_DATITL = "6"
This data set does not have a "dataset title" so that label is
empty. The "logo" with the Ferret version, date, etc, is drawn
using moveable labels, so if we remove that, the label numbers
change. The labels above the plot are drawn with moveable labels.
yes? cancel mode logo
yes? use levitus_climatology
yes? shade/y=45 salt
yes? sh symbol lab*
LABX = "LONGITUDE"
LABY = "DEPTH (m)"
LABTIT = "SALINITY (PPT)"
LAB1 = "LATITUDE : 44.5N"
LABNUM_Y = "1"
LAB2 = "DATA SET: levitus_climatology"
LABNUM_DSET = "2"
LAB3 = ""
LABNUM_DATITL = "3"
The label numbers change but the descriptive symbols LABNUM_DSET,
LABNUM_Y, and so forth can always be used in scripts. In the
terminology of PPLUS, the X label is the horizontal axis, Y is the
vertical axis.
These symbols are set on a SHADE/SET so they can be used to
say, remove the dataset labels at the top and make the label in the
upper left smaller
shade/set/z=20 salt
GO unlabel ($labnum_dset)
GO unlabel ($labnum_datitl)
ppl hlabs,($LABNUM_z),.08
ppl shade

I think
PPL LISTSYM
gives all the variables PPLUS knows about.
It's a long list and not especially transparent (and only gives
information after a plot is made), but might be useful. It will not
do quite what you want because successive plots of different
sizes/shapes will have different values of label numbers, axis
lengths, etc (those will be numbered successively, so it could be
useful for the first plot in a new Ferret session).
But in general, as Ansley says it's better to specify the label
height directly (LABSET for axis labels, LABEL for handmade ones).
Then there's no ambiguity.
Great, that's a useful command to check some things. I presume you
cannot directly change these variables, or you are not supposed to?
But to my issue. The variable returned by
PPL LIST LABSET
are not in the PPL LISTSYM output. I rather get some unconveniently
formatted output. Can I save that in some way to a variable?
I just want a jnl script to read the default font sizes, apply a
scaling factor on them in LABSET, and plot them thus. In the end,
there are just a couple of values \in {0.16, 0.12, 0.10} inch, so I
could hard code them in my scripts: they are after all default values.
But I thought there may be a more elegant way to do it.
