This is the indicator originally posted here Limit channels that is extended with a display of "states".
"states" are displayed as colored histogram
they can be calculated using :
level 3 - outer levels - the "slowest"
level 2 - middle levels
level 1 - the inner levels - the "fastest"
Recommendations:
This is just a suggestion how the levels of this kind can be used
A lot more combinations from 6 levels can be added but that is left to the discretion of anybody using the levels indicator
You can use color changes as possible "signals"
