Hello every user.

Is there way to calculate time interval peak to peak?

More exactly, want to get period between the latest peak value and former peak value whenever data updated

And that period is irregular.

Is this possible using PE or VBA in Process book?

Wowww Lim,

That's a nice problem to solve with PI Calculations!

It seems easy for periodic functions by nature, but I am afraid it is more complex to realize on general timed data series.

What if I had the following trend based on my archived values?

If looking for the two highest peak, it'll give false result...

Or I need additional parameters to find the right peaks resulting the correct period... Just like ex.in stock-exchange trend analysis...

But I am sure, basically it can be achived with PE with additional tags, or with some nice VBA macro!

At first glance,
