[Gnuplot-info] change colors of bars, and add small digits

[Emanuel B. <emb...@st...>]

I have a project going on here:

    http://user.it.uu.se/~embe8573/everest-plot/

If we focus on this plot:

    http://user.it.uu.se/~embe8573/everest-plot/early.png

I'd like to change two things:

    1) How can I give the bars more different colors?
       Especially if printed on a black-and-white
       printer, the bars get too similar. Instead one
       can be black, and the other white (with
       a border).

    2) How can I add small digits above each bar,
       saying the number which the bar illustrates?
       E.g.,

             3
          2  |
          |  |  1
          |  |  |
         ---------

Here is the .gpi file:

# This file: http://user.it.uu.se/~embe8573/everest-plot/everest.gpi

set terminal png size 800,600 font "cm-super"

datastring = sprintf("%s", data)

set xtics 1 font ",8" rotate by 90

if (datastring eq "early.dat") {
    set ytics 1
    set key left top height 1
    set title font ",14" "Mount Everest: Framgångsrika bestigningar, dödsfall"
    set xtics offset 0.2,graph -0.0475
}
else {
    set ytics 20
    unset key
    set xtics offset 0.2,graph -0.045
}
set ytics font ",6"

set grid

set style data histogram
set style fill solid

plot for [COL=2:3] datastring using COL:xticlabels(1) title column
