</div>

```auto
const agg1 = msg.payload[0].Agg1_Total_Weight
const minvalue = agg1.minvalue
const maxvalue = agg1.maxvalue
const difference = maxvalue - minvalue
return { payload: { minvalue, maxvalue, difference } }

```

This will output a msg like:

```auto
msg.payload: {
  minvalue: 1000,
  maxvalue: 2000,
  difference: 1000
}

```
