Another HP HMI thing: "Only show information that is immediately
relevant". Let's hide the pirani voltage as it is mostly no longer
interesting to the user. For situations where it is, it can be revealed
by hovering over the pirani pressure value.
In the process automation world, there is a trend to move away from
colorful user-interfaces, towards more "boring" colorschemes. The
argument is about situational awareness - by only using colors to
highlight abnormal situations, they become instantly recognizable to the
operators.
This design philosophy is outlined by the ISA-101 [1] under the name
"High Performance HMI". While it covers much more than just colors, I
think this is the most important part and the one that is most
applicable for our usecase.
So let's do a bit of HP HMI - reduce colors usage such that only
important information is highlighted.
