Hi all,

I'm trying to see if there is a way to customise the quality overlays on ignition perspective components. My goal is to overlay a different colour error overlay if the tag bound is 'BAD Out Of Range".

My understanding is that ignition selects the overlay (pending, unknown or error/bad) based on the respective range of quality codes. is there a way to further differentiate between specific quality codes within these ranges and apply specific styling?

Thank you in advance for your help,  
Alex.

Not ranges, per se. Instead, there are two high bits, that signal the quality category. Both zero is "good". Other combinations indicate "Bad", "Error", and "Uncertain". Low order bits indicate the specific reason. There's no rhyme or reason to the assignment of the low-order bits. You'd have to match very specific codes.

Thank you for your fast reply!! Would you be able to direct me to where these signals are being read and relative styles are being applied to the components? I'm not sure where the customisation would take place.
