[Gnuplot-info] functions and/or macros and/or substitutions

[<rhu...@ih...>]

In a previous post I was adding the underlying y-values as labels to the
bars.  For some bars that were shorter I want to change the label offset.

I tried some things and none worked, is it possible to change the offset
this way?

poff(t) = sprintf( 'off gr 0,%f',(t < 20000) ? 0.04 : 0.00)

plot 'immigration.dat' using 6:xtic(1) title col, \
'' u 12 ti col, '' u 13 ti col, '' u 14 ti col, \
'' u (($0-1)-0.3):6:6 w labels left rot by -90 offset graph 0,0.02 notitle, \
'' u (($0-1)-0.1):12:12 w labels left rot by -90  poff($12) not, \
'' u (($0-1)+0.1):13:13 w labels left rot by -90 off gr 0,0.02 not, \
'' u (($0-1)+0.3):14:14 w labels left rot by -90 off gr 0,0.02 not

and I tried this 

plot 'immigration.dat' using 6:xtic(1) title col, \
'' u 12 ti col, '' u 13 ti col, '' u 14 ti col, \
'' u (($0-1)-0.3):6:6 w labels left rot by -90 offset graph 0,0.02 notitle, \
'' u (($0-1)-0.1):12:12 w labels left rot by -90  off gr 0,($12 < 20000) ? 0.04 : 0.00)
 not, \
'' u (($0-1)+0.1):13:13 w labels left rot by -90 off gr 0,0.02 not, \
'' u (($0-1)+0.3):14:14 w labels left rot by -90 off gr 0,0.02 not

I also tried macros and substitutions with no success.
