I'm not sure if this gives the correct result. You want binned results,
not density estimates, right?

you mean the width of the actual boxes in the plot?

Check "help style boxes": You need to give a third parameter to your
plot to specify it.

   plot dataf using (bin($1)):(1):(plot_width/numberofbins) smooth freq

Oh. What is your gnuplot version? The "fnormal" smoothing routine first
came with gp5.2 last year.
