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"
