I read that. I've read a bunch of stuff.

I am.

Ok.

I understand that. I think you are making an assumption that I don't.

That's great...that's what I understand too. Again, I don't care about the
normalization because if and when that occurs my graph would be close and
useful. So, let's drop that for our discussion.

That's fine by me. As stated numerous times...I said it doesn't have to be
exact. Just CLOSE/USEFUL.

I already have done you and myself the favor. Once again, you are making
the assumption I have not. I nor asked or officially requested you to
repeat yourself.

I would set the min graph value to 0 so I would not see a -4 as -4 isn't
useful.

If you aren't willing to assist me, then why be condescending? Why not just
either be helpful or not post? I didn't come here to have people make bad
assumptions and be treated like a jag. I came here because I felt that I've
spent too much time trying to find what I'm looking for...therefore I
reached out on this list.

I am asking for help because I've spent numerous hours reading documention
as well manually searching the archive (as well as experimenting) because
the search isn't the greatest thing in the world.
