plot errorbars

hi, i am trying to make a plot of errorbars using the plot command.
i think i have tried all ways, but i always get the same error:
error: invalid number of data columns = 2 specified for plot style
i looked at the gnuplot web-site and i thought something like the
following should work:
x = [1 2 3 4]
y = [2 3 3 4;0 1 0 1;3 2 1.5 2.5]
(where i wanted y(1,:) to be a mean value and
 y(2,:) y(3,:) min and max values of a function z(x))
and called plot(x,y,"~")
but it doesn't work. anyone there to help?
