gnuplot partially stacked bars

I would like to make a gnuplot graph with one full bar and another one stacked. The data is something like

x   data    E   M   L
[10,20) 0.000000    1.081916    2.0958133   5.473606
[20,40) 0.000000    2.331769    2.1402838   4.528341
[40,80) 3.262375    2.201788    1.3499280   3.023847
>80 2.368121    2.132216    0.7322889   2.610368

where E, M and L are the three "green" components.

I have tried to do something like 

set style data histograms
set style histogram rowstacked
#set style histogram cluster gap 1
set style fill solid
...

plot newhistogram, "size_class_data/tree_paracou.txt" using 2:xticlabel(1) linecolor rgb data_color title "Model",\
newhistogram, '' using 3:xticlabel(1) linecolor rgb early_color title "d",\
'' using 4 linecolor rgb mid_color title "g",\
'' using 5 linecolor rgb late_color title "f"

but the two graphs lie on two different parts of the x axis. enter image description here

The newhistogram command has an option at for setting the coordinate of the first box.

In you case you can fix the boxwidth, and start the second histogram at 0 + boxwidth:

set style data histograms
set style histogram rowstacked
set style fill solid
set boxwidth 0.33 absolute

plot "foo.dat" using 2:xticlabel(1) skip 1 linecolor rgb "black"  title "Model",\
newhistogram at 0.33, '' using 3 skip 1 linecolor rgb "red" title "d",\
'' using 4 skip 1 linecolor rgb "green" title "g",\
'' using 5 skip 1 linecolor rgb "blue" title "f"
