Hi  
I'm trying to format a ui-gauge to display a range of values (of electrical current) from -30 to +30.  
I'd like the gauge to show a red coloured arc starting from centre zero when the value is negative and a green arc when the value is positive. The default behaviour is for the colour sector to start at the gauge min

Is there way to change behaviour of ui\_gauge so that coloured sectors start from a center zero rather than value min?  
I've looked through the reference for `msg.ui_control` but cant find what Im looking for.  
Many Thanks  
NR V1.2.9

Hi - no that is not possible with the standard gauge - but I think the artless gauge can do it - [node-red-contrib-ui-artless-gauge (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-ui-artless-gauge)

Thanks for taking the time to respond. I'll try the artless
