It is not possible to overlay two or more gauges because the top level gauge will always hide the lower level gauges. A solution could be to support a sta choise "transparent" so only the needle is updated. Examples for such an employment are: 1. clock with hands for seconds, minutes and hours 2. measuring instrument with a needle for max and min indication etc.
Maybe we can do it like Waveform.To add more channel.
Hehe,This is my personal opinion, which is not on behalf of @ITEAD Support Team.
I am now reviewing all of the Feature Requests, this will take some time, patience please.
Currently multiple gauges on top of each other is not possible as you described.
Multi-needled gauge carries forward.
