Hm. "every" is not what you want. I'm not even sure how it should work
with matrix data.

Limiting the y range with "stats matrix" indeed doesn't work:

  $dat << EOD
  10 10 10
  20 20 20
  40 40 40
  100 1000 10000
  EOD

  stats [:] [1:1] $dat matrix

The second range specifier refers to the data (z) values, not the
constructed abscissa values. "set yrange" has no effect.

And there seems to be a general problem with stat matrix, it interacts
strangely with splot:

  splot $dat
  stats $dat matrix

gives the mean of the x-axis values (here 0,1,2), as long as that splot
is the last plot command. If you give

  plot $dat
  stats $dat matrix

the correct mean is again returned.
