Thanks for the "--band"-option, Allin. It's quite useful.
Best,

To see what this does in practice you can compare these two plots:
<hansl>
nulldata 50
set seed 12345
setobs 1 1 --special-time
series y = normal()
series upper = y + 2
series lower = y - 2
list L = y upper lower
gnuplot L --time-series --with-lines --output=display
gnuplot L --time-series --with-lines --output=display --band
</hansl>
Yes, it would be nice if you could also set the style of the band (e.g.
make it a shaded area rather than two lines). That may come,
but it's a lot more complicated.
