My gnuplot file is:

set nolog x; set log y; set log z
set xtics 45; set x2tics 9; set grid
set yrange[1:100]; set ytics 10; set mytics 10
unset ztics; set view 0,0
set xlabel "right column" ; set ylabel "middle column"
set label "1000" at -90, 3.5, 1000
splot "mydata.txt" using 3:2:1 with lines \
title "my position according to left column value"

mydata.txt contains:

100  100   0
200  80   -20
500  4    -60
1000 3.5  -90
2000 1.1  -120
4000 1    -180

Can I make the set label line more automatic, in the sense that Gnuplot 
will automatically fetch the line of mydata.txt containing 1000 in the 
left column, instead of copying the two other values of this line into my 
set label line? My data file will change!
