! Main plot.

begin graph
    size 8 8
    fullsize
    axis grid color gray10
    labels dist 0.5 color black hei 0.5
    xtitle "Minutes until eruption" hei 0.5 dist 0.60
    ytitle "Duration in minutes" hei 0.5 dist 0.80
    data "margins.dat"
    d1 marker fcircle color rosybrown msize 0.15
end graph

! We add two marginal plots. The data in each plot are obtained with 'hist'.

amove 3 11
begin graph
    size 8 2
    fullsize
    yaxis min 0 max 50
    axis off
    data "margins.dat" d1=c1,c1
    let d2 = hist d1 from 40 to 100 bins 20
    bar d2 width 3 color rosybrown fill rosybrown
end graph

amove 11 3
begin graph
    size 2 8
    fullsize
    xaxis min 0 max 50 dticks 50
    axis off
    data "margins.dat" d1=c2,c2
    let d2 = hist d1 from 1.5 to 5.5 bins 16
    bar d2 horiz width 0.25 color rosybrown fill rosybrown
end graph

! We conclude with marginal axis decorations.
