I need to average one point on the graph to another, without exporting all the recorded content, only the selectable content. And I need to export it via Excel. How do I do this? Is there a method?

I need to average just this one pen that is circled:

You could used a History Statisitcs Tag, or script a filter - see links below:

So, let's go... I need the average to be cyclical. I noticed that this "Historical Statistics" tag calculates the average of the entire variable. It's like going from "point A" to "point B" = average (A and B). Then, it will present another cycle... "point C" to "point D," and so on.

The value of this average will be generated by Excel. I'll take some random numbers as an example, so you can visualize.

Cycle 1 (red) = Average (15, 20, 30, 10) = 18.75

No values ​​(values ​​zero and less than 0 do not appear).
indicated in gray.

Cycle 2 (green) = Average (12, 75, 36, and 23) = 36.5

No values ​​(values ​​zero and less than 0 do not appear) - indicated in gray.

And so on.

And at the end of each cycle, calculate its average. When it reaches 0 or less, it indicates a new cycle.

I'm racking my brain for a solution.

Note: it is just one variable that is in this cycle. It presents values ​​above 0...and does not present values ​​below zero (negative) and equal to zero (invalid);
