Gauge - Dynamic min and max

[dynamicdave]

Here's my test setup.

This is what I put in the first function node...

var max = 50;
var min = 20;
var data = 30;
msg = {payload:data,ui_control:{min:min,max:max},topic:"Soil"};
return msg;

The second function node is the same but with different values for max, min and data.

Hope this works for you.
