[Gnuplot-info] Setting labels position while plotting with labels

[Amir S. <ami...@gm...>]

Hi all,
I am trying to plot a crown of 72 points with labels reporting the name of
the point.

The data file is structured like this:
#ID x y z
P01 1272.5113 -0.1213 1298.4915
P02 1272.5609 -113.2659 1293.49
P03 1272.6138 -225.5753 1278.7028
P04 1272.655 -336.1809 1254.1747
P05 1272.7575 -444.2176 1220.1453

I would like to have the label with ID of the points outside the crown.
I have thought of a ternary operator:

plot FILENAME using 3:4:1 notitle with labels at ($3>=0 ? $3+10 :
$3-10),($4>=0 ? $4+10 : $4-10), \
FILENAME using 3:4 title "ring points"  with points ps 3 lw 5 pt 1 lt 7

But it doesn't work.

Where I am doing wrong?

Thank you
Amir
