Randy -

You set this up with defined names, such that the Y values is defined
based on an integer value in another cell. Something like

Name: YValues
RefersTo:
=Offset(Sheet1!$A$2:$A$12,0,Sheet1!$E$1)

As the value in E1 increases, the range defined by the Offset is further
and further to the right. Your chart is based on these YValues.

Then you have a macro that moves forwards or backwards through the data
by changing the value in E1 by a certain amount after a given delay.
Shorter delays mean the curve changes more quickly.

I would like to be able to view my data set such that I can view the curve
change over time instead of viewing for example 10 curves on one graph. I
would like to be able to select the speed at which the curve is refreshed
(new data set), and the direction (so I can run the curve forward and
backward in time).

In essence, I have monthly data that represents one curve. I would like to
visually watch the curve change month by month instead of plotting one curve
for each month, I see one graph with the curve in motion over my data set
(time).
