[Gnuplot-info] how to suppress x axis labels in stacked multiplot?

[Skip M. <sk...@po...>]

I have a multiplot which looks like this:

clear

set multiplot layout 3,1
    load "p1.gnu"
    load "p2.gnu"
    load "p3.gnu"
unset multiplot

where each of the p?.gnu files defines a single plot.
All three plots have the same x range.  Reading the docs
for the set xtics command I couldn't figure out how to
have just the p3 plot display x axis labels.  All the plot
files have this overall form:

set grid xtics ytics
set xdata time
set timefmt "%H:%M:%S"
set format x "%H:%M"
set xrange ["09:00":]
set key right bottom nobox
set ytics nomirror
set xtics nomirror

plot ...

I tried

   set xtics ""

in the p1 and p2 plot files followed by

   set xtics

in the p3 plot file but none of the plots had x labels.
Is there some way to let it compute the labels for p3
and suppress them for p1 and p2?
