[Gnuplot-info] plotting a line

[markjoe <na...@ma...>]

Hi all,

Use gnuplot already ages, still I don't know all. E.g. I produce year plots
of something, very simple datafile, one column: plot 'data' using 0:1 pt 7
ps 0.5 etc. Suppose I want to make a vertical line at today's date, exactly
from top to bottom axis. I want to keep autoscale for y because that
produces nicer plots. How to draw that line? I don't know the exact maximum
gnuplot will choose for it's maximum. Any ideas?

Thanks, Mark
