Height macro request ...

[rocket1406]

Is it possible to do this:

Give me height values underneath the width values.

You guys have already helped me with getting the width values:

My definition of a height value:

For each region of blue cells, I want it's "highest peak value" minus the "first blue value" in it's region.

So for example.

0.5
0.55
0.6
1.8
0.6
0.59

so in like Column C, underneath the width value, I want the height value:
1.8 - 0.5 = 1.3

I'd like this for every blue region in all columns of a spreadsheet ranging from A:AZ, with rows going all the way to 2000.

Is this possible?

Thanks so much
