Ok still learning Node-Red and still struggling with it, however, I could do with some help trying to create bar charts, I am bringing in an array like this and spent 2 days on it, so given in and asking for help 🙂

I know how the data should be like the below example I just cannot get into that format, lack of knowledge!

```auto
[{
    "series": ["X", "Y", "Z"],
    "data": [[5], [3], [6] ],
    "labels": ["Jan"]
}]

```

Also if anyone can point me the direction of a good book on Node-Red I would appreciate it
