Thank you. Just tried it but it makes the led array disappear altogether.  
It may be something to do with the else. I do not fully understand what this is:

```auto
            }else if (typeof $scope.msg.payload !== "number"){
                $scope.msg = {"bargraph":[...bargraph], "payload": 0, "label":label}
            }   
        }else{
            $scope.msg = {"bargraph":[...bargraph], "payload": 0, "label":label}
        }

```

In the original code msg.payload was a number. I do not know what to put here in its place ?  
P.S. I started a new topic [https://discourse.nodered.org/t/dashboard-template-led-array-problems/50022?u=ozpos](https://discourse.nodered.org/t/dashboard-template-led-array-problems/50022)
