Normalize the data that feeds the chart. To normalize your data to MIN = -1
and MAX = 1, use a formula like this:

=2*(B2-MIN(B$2:B$1000))/(MAX(B$2:B$1000)-MIN(B$2:B$1000))-1

where your data is in B2:B1000, and this formula is to normalize the first
point, in B2.

I have the graph of the historical prices of a stock. I was wondering
whether
it can be normalized. To clarify, I would like to see a graph with (-1) to
(1) on the y axis and time on the x-axis. The trend line of the stock
price
data would be considered zero and the moves above or below that line would
be
depicted between -1 and 1.

If anyone knows whether there is a function/graph type in excel to perform
this task, your assistance would be greatly appreciated.

Thanks.
