[Gnuplot-info] use of different Colors in histogram

[nicolaslac <nic...@gm...>]

Hello,

I would like to create histograms using one color for the n firsts columns
and
other one for the remaining columns...

Variable color seems to be a hint, but seems to be too complicated for my
simple
need.

I read
http://old.nabble.com/Plot-boxes-with-color-determined-by-column-data--td27483709.html#a27488996
http://old.nabble.com/variable-color-in-histogram-tp27852750p27852750.html

Here are my final investigation...

8<--- sample.csv
toto;1
tutu;2
lolo;6

8<--- gnuplot session
set key off
set datafile separator ";"
set boxwidth 0.8
set style fill solid 0.4 border
set grid ytics
set yrange [0:8]
plot '<sort -n -t\; -nk 2 -r sample.csv' using  2:xticlabel(1) with boxes lt
rgb "dark-blue"

plot '<sort -n -t\; -nk 2 -r sample.csv | head -n 1' using 2:xticlabel(1)
with boxes lt rgb "dark-blue",\
     '<sort -n -t\; -nk 2 -r sample.csv | tail -n+2' using 2:xticlabel(1)
with boxes lt rgb "red" 
8<---

the last command is not satisfying... values on the x axes are
overlapping...
