(gnuplot version? following is done with 5.2pl2)

Hm, the following fills the polygons with the demanded colour
alright. The last polygon breaks open if you remove the empty line
behind it. Looks like a separate bug to me.

===========
$dat << EOD
1 1 10
1 2 10
2 2 10
2 1 10

3 1 20
3 2 20
4 2 20
4 1 20

1 3 40
1 4 40
2 4 40
2 3 40

EOD

#set yr [20:35]
#plot $dat u 1:2:3 w filledcurves closed fillcolor palette
plot $dat u 1:2:3 w filledcurves closed palette # does the same
============

If you uncomment the yr setting, the filling becomes monochrome,
however. Seems "palette" and "filledcurves" don't agree on how to
use the value in the third column.

All in all, also after trying to find it in the help, i think this
is not really supposed to work.
