Re: [Gnuplot-info] 3D - histograms

[Noel-Monash <noe...@me...>]

Hi Hans,

Sorry, I'm really not describing what I want well!
There are two major series, each with three sub-series. If I plot each 
major series individually as a histogram it would look something like this:

8 | #
7 | #
6 | #
5 | #
4 | #                 &
3 | # * &         #   &
2 | # * &    *    #   &
1 |_#_*_&__#_*_&__#_*_&_
            1            2            3   
                        Lengths
The y-axis is the 'number of occurrences' at that length.

# sub-series 1
* sub-series 2
& sub-series 3

What I want to do is plot each major series along the z axis (and each 
sub-series along the x-axis)
Each sub-series are the same i.e. (TCC, TCA, TCG) but each major series 
is different (different species).
I've tried to do this in excel, however it interprets each sub-series an 
individual series thus resulting in the graph shown in the attached pdf. 
What I want is the first three series grouped together and the next thee 
grouped together.

I hope this helps.

Many thanks,

Noel
