Trend updating time

Hi, did somebody know what is the time between two value in a trend? I would like to know what is the lapse of time between the first point (value) of a curve and the second point in a Trend…Because I want to know how much data i got in the average section of the trend.

Also, is there a way to change the number of data for a certain lapse of time?


I am pretty sure you can use the easy chart extension functions to capture data in x trace mode into some memory tags from two different points in time on the chart and calculate from there. I have done this to calculate Delta PV over the span of time selected.
