Ron,

That's an excellent point, and one that I also am considering...
It's not for financial data, but rather quantity of products sold.

Nevertheless, your comment is well appreciated and does tend to make me
re-consider the whole approach.


I would think so. Although I'm not sure how Quantity of Products sold could be
a negative number. Maybe it's the net of product purchased vs product sold;
but if that's the case, I would think the same analysis would apply.

The above doesn't read right and might be offensive.

What I meant to write, in addition to not being sure how negative values would
apply to quantity of products sold, is that I would think that similar
principles would apply if one or both of the values were negative, or zero.
