horizontal error plot

[chelle]

Hi, 

Is it possible to plot horizontal error bar with Octave ?
To plot vertical error plot, it's easy: gplot datat using 1:2:3 w e

but to plot horizontal error bar, ?
I tried to plot "manually", by doing a multiple gplot that plot the data and 
each error bar separately. It works to plot only one error plot, but when I 
want to plot several curves (with hold on), I reach the limit of the capacity 
of the string where Octave stores the last plot.
