With the minimum point, I want to use that to subtract from each data point.

Here's a simplified version of what i am asking.

1 -1

2 1

3 0

4 -5

5 -4

6 -3

7 -2

8 7

9 5

10 0

11 -3

12 0

The max pts would be 1 and 7, the lowest point between this period is -5.

Then the third colum would take each value in column 2 and subtract -5 from it.

Sorry it sounds a little confusing, but i feel finding multiple maxiums must be possible on excel. Thanks for any help!
