Apologies for this newbie question..
I've made a flow that works fine with the built in gauges from dashboard node.
However I wanted to use a gauge in the UI template node from d3.js.
I put the code from this link in the UI template.
However i'm stuck in how to get my flow.get("value") or dynamic numbers into the (var value = 17;) line.. replacing 17 ofcourse..
isn't there a quick line of code that could fetch my msg.payload into the value variable??
