Re: [Gnuplot-info] how to plot different values of a file with different color

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

instead of a histogram you may use boxes:

set xrange [-1:7] 
set yrange [-1.5:1.5]
set style fill solid 0.5
set palette defined (-1 "black", .25 "green", 1 "red")
plot "file1.dat" us 0:2:(0.5):2 with boxes lc palette notitle, \
"" using 0:($2>=0?$2+0.1:$2-0.1):1 with labels notitle
