I've been diving into forum and docs, but I think I'm going in the wrong direction.
I'm trying to show a multi-series line chart. Only 3 data in the query: date, device and data. The format in query is like that: devicename (string) | date (datetime)| data (float)
What I want is to show a line for every device and see data along the time. I've seen several examples with xml, but none with json.
Could anyone show me an example of something similar? I know there must be lots of them, but I cannot find even one. My main problem is arrange the json. I have no experience with it but I think I coud use an example as a guide.
Thanks for all!
