#3166 — plotting a grouped columns

Hi,

I've a data file of the form x1, x2, x3, y which I generated after a bench tests. All xi variables has 5 possible values.
Any hint on how I could plot this using gnuplot?

bests,

When you plot a datafile, there is no real difference between
abscissa and ordinate values:

dataf = "filename.dat"
plot dataf using 1:4, dataf using 2:4, dataf us 3:4

?

Thanks for the hint, however y=f(x1, x2, x3) so I can't just plot y for x1, than add a graph of y for x2, ..
I'm looking for a way to group the xi variables, I was thinking about having x1 at the abscissa and y for ordinate then for each x2 value i'll have a line, but don't know how to do so!!!

I don't think i exactly understand what you're after, but have you
seen the plot style "with vectors" ?

  plot dataf us 1:4, dataf us 2:(0):(0):4 with vectors nohead

Do you mean 3 x-axis? You can't have a line for each value. A value is 
only a point.
Or something like Parallel axis?
