Max column resets, why?

Hello,
I am trying to build a graphing log to show the Max times between routes.
After checking the plots, I see many at long times.
Then, when I check again, the are gone, and shorter times are displayed.
Why?
I want ALL Max times periods.
This should never change.
BTW, I am using the free version.

Okay, installed the Standard trial.
Max column data is STILL resetting.
This is NOT good.
I am wanting the MAX data for the complete duration run.
What am I doing wrong?

The "Samples to include" setting controls how many samples to look back for statistics. Changing this to 0 ("All") should do what you're after, based on your question.

PERFECT!
Thank you for your support!
This is a great tool.
I will be purchasing now.
