Hi I have the following code:
(See question at the end!)
**********************************************
clear
reset
unset key
set auto x

blue = 0x0000ff         # RGB components for pure blue
cyan = 0x00ff00         # RGB components for cyan
red = 0xff0000          # RGB components for red

set xtics rotate by 90 offset -1.5,-5

set bars fullwidth
set style fill solid 1 border lt -1
set style data histograms
set style histogram errorbars gap 1 lw 1

set title "Intensity of luxA signal for different substances"

set output 'luxA.png'
set terminal png transparent nocrop enhanced font times 18 size 1024,768 

set ylabel "luminescence intensity"

set grid  ytics noxtics

set xtics scale 0

plot 'luxA.dat' using 2:4:xticlabels(1)
**********************************************

and the following data:

Everything I want to achieve now, is to get every box of the histogram according to its color code in the data (instead of numbers, there could also be strings e.g. "red", "green", etc). How can I do that?

A second thing: It would be cool to make it possible, to group the same colored boxes spacially (the boxes with the same color are closer, between the groups the gaps are bigger). How can this be done!
