You probably need to re-think this a bit: as you say, the point {0,0}
on a log scale is the equivalent of {-Infinity,-Infinity} on a linear
scale, so what you are asking for makes as much sense as asking "how
do i include the point {-Infinity,-Infinity} in my linear plot?". i.e.
it can't be done (not on a finite screen anyway)!

Cheers,
Peter.
