The "lines" I'm seeing are where the prime occurs as the leading digits
of the square. Every number up to (but not necessarily including)
5*10^(n-1) occurs as the leading digits of an n digit number, so any
target not found until then will occur at that point. You'll then
continue to see more such values, gradually thinning out.
I find it a bit surprising that this sequence is in the OEIS, and not
the
simpler "smallest m such that m^2 contains n as a substring" (unless
I'm making a mistake in searching for it).

Dear seqfans,
Graph of A029944 contains several "lines" -
any idea about their origin?
thx, zak
