Hi,
I want to add VFD control box in which I'd display Current, Voltage, Power, DC Voltage etc. and below each number a nice bar that would scale according to input numbers.
I configured SerialBus plugin for each parameter and small brain script with each parameter assigned to different Local Variable (from 1 to 8).

I stuck in screen editor. I thought that it is possible to refer to local variables but there are only DRO and OEM functions.
Can I do it using local variables and screen editor or I need to write VB Script?

I've tried to google something but no results. I'm not sure what to look for as I've never edited screens and have no experience.
Can you help me with displaying this numbers with bars and reconfiguration of brains (if necessary).

Best regards
Bart
