[Gnuplot-info] help requested creating histogram - error

[melysion <ali...@ya...>]

Hi there

I don't use gnuplot very often, so don't know anything beyond the basics.
I've recently been asked to modify a plot that I created using gnuplot a
while back

Heres the script

set terminal postscript enhanced color
set output 'pic.ps'
set autoscale                        # scale axes automatically
set xlabel "Number of SSGs" font "Helvetica,15"
set xrange [-0.5 : 11.5]
set x2range [-0.5 : 11.5]
set yrange [0.0 : 310  ] noreverse nowriteback
set ylabel "Number of items" tc lt 1 font "Helvetica,15"
set y2range [0.0 : 540000 ] noreverse nowriteback
set y2label "Population in 2" tc lt 2 font "Helvetica,15"
set ytics nomirror font "Helvetica,12"
set y2tics nomirror font "Helvetica,12"
set xtics nomirror font "Helvetica,12"
set tics out
set style data histogram
set style histogram cluster gap 1
set style fill solid border -1
plot "final.csv" using 2:xtic(1) title col fs solid lc rgb "blue", '' using
3 title col fs solid lc rgb "pink" axes x2y2

When I try to run it, I get the following error

set style data histogram
                                 ^
         "simax_eap_genome.gnuplot", line 15: expecting 'lines', 'points',
'linespoints', 'dots', 'impulses',
        'yerrorbars', 'xerrorbars', 'xyerrorbars', 'steps', 'fsteps',
        'histeps', 'filledcurves', 'boxes', 'boxerrorbars',
'boxxyerrorbars',
        'vectors', 'financebars', 'candlesticks', 'errorlines',
'xerrorlines',
        'yerrorlines', 'xyerrorlines', 'pm3d'


I am using gnuplot 4.0. I think that at one time, I was using gnuplot 4.1
(I've changed computers since) which I guess might cause some problems. I've
never had this error before so am a bit confused.


Also, I'm not sure how to specify the colours of the bars. Is the code below
correct?

plot "final.csv" using 2:xtic(1) title col fs solid lc rgb "blue", '' using
3 title col fs solid lc rgb "pink" axes x2y2

Thanks in advance for your help!
