I have thought about this, but haven't gotten around to doing it.  To=
 do=20
the whole job, we could handle a single NxK argument, and we could al=
so=20
handle pairs:
Nx1, NxK
NxK, Nx1
NxK, NxK

I think it is clear what the behavior should be with any of the pairs=
;=20
essentially they should be broadcast to the NxK, NxK case, resulting =
in=20
K lines.

In the single-argument NxK case, I think matlab plots subsequent colu=
mns=20
against the first column.  Is this what you would like?  The alternat=
ive=20
would be to plot each column against the row index, which is what=
=20
happens in the Nx1 case, but I suspect the matlab-compatibility argum=
ent=20
wins out here.  Also, this maintains consistency with the original=
=20
request for Nx2, which I assume was for plotting the second column=
=20
against the first.  I certainly would not want to have NxK behavior=
=20
change as K goes from 2 to values larger than 2.
