Re: [Gnuplot-info] plotting wthout certain value

[Thomas S. <t.s...@fz...>]

there are several ways:

a) ternary operator in 'using' option:
plot "datafile" using 0:($1>0?$1:0/0) with linespoints

b) specifying "0" as missing character:
set datafile missing "0"
plot "datafile" with linespoints

c) filtering outside of gnuplot:
plot "< awk '{if ($1 > 0) print $0}' datafile" with linespoints
BUT this will change the numbering of your points
