To: David Winsemius <dwinsemius@comcast.net>


Thanks David and Michael,
In attachment there is one of the graph.

the line below the graph is not related to the y label.
I draw it at y= -10 just becouse it was the only way I know for draw a line
parallel
to the x axis.
But it shoud be "out" of the xy axis.

It rappresents another variable related to the one shown in the graph...

Sorry for not being very clear :)

Claudio
