[Gnuplot-info] stacked charts

[<ton...@le...>]

In another message I mentioned I made stacked charts.  Here is my question about them.
It does not seem there is a way to stack charts.  If you plot 2 bars, they will both start at 0
and one will overwrite part (or all of) the other one.

I had 5 fields to plot (say 2, 3, 4, 5, 6) with the x value as field 1 (1, 2, 3, ... 24).  What I end up doing is

plot "file" using 1:($2+$3+$4+$5+$6) with boxes title "field5",
      "file" using 1:($2+$3+$4+$5) with boxes title "field4",
      "file" using 1:($2+$3+$4) with boxes title "field3",
      "file" using 1:($2+$3) with boxes title "field2",
     "file" using i:2 with boxes title "field1"

but it seems like there should be a simpler way to stack them than that.  Is there?
