Graphs for SteelSeries Gauges

Hello

I have tried to find where to set up and configure settings (which file?) for the different graphs, but after reading a lot, I’m still very confused.
I have looked through SteelSeries Graphics posts,including the mega-thread, without luck.
What I want to, is to change some of the min/max-values, like for the pressure and also other values/graphs. When the graph shows the whole span from 940 to 1060 mb, it’s almost useless.
Seems that somebody has much better resolution than I have on my graphs, like this: http://monadh.com/nbl.php

Setup:
Win10, WD 10.37S b69, SteelSeries 2.6.1/Scripts: Mark Crossley - version 2.6.4
