understand the horizontal axis is time and the vertical is the +/- change in pressure and each dot is a reading. it's been the same for awhile now with the same dot blinking at me and the graph hasn't changed/updated recently - or more honestly since I've been watching it.
i know for a fact the graph is different than yesterday, but honestly I was trying out other features till today. am I just impatient?!? is it a matter of "a watched pot never boils?"
