Good stuff.

Possibilities:

1.  For a selected column, it can be nice to draw a histogram.  Long
ago, I developed the following formula for choosing a bin size.  Seems
to work.

        5*(max-min)/n

You can use something like bin*round*($1 * (1.0/bin)) to bin.  Note
that cl-extra.el's (round*) might be more consistent and
mathematically vetted than (round) (though you might not be allowed to
use cl-extra.el).

I haven't looked at gnuplot in a decade, so maybe it already has this.

2.  It might be nice to show descriptive statistics (I would show
mean, median, geometric mean, standard deviation, min, max, range)
somewhere while showing the plot, if you don't already do this.
