Here's a typical document I'm working with:

```
    "_source": {
      "timestamp": "2017-04-26T08:28:00",
      "signals": [
        {
          "par": "signalA",
          "value": 76.36666666666666
        },
        {
          "par": "signalB",
          "value": 96
        },
        {
          "par": "signalC",
          "value": 72
        }
        }            
      ]
    }
  },

```

where "signals" is _nested_. Question:

How can I plot any (or multiple) of these signals as a function of time?

Thank you!

Kibana currently does not support nested object. [https://www.elastic.co/guide/en/kibana/current/nested-objects.html](https://www.elastic.co/guide/en/kibana/current/nested-objects.html) mentions some workarounds.

Is there a reason you need to have signals as nested? If it was an object you could chart them all over time.

Thanks for the answer, Tyler! In the project that I'm working on, people had used this kind of structure before me. I guess back then it kinda made sense but now I'm not too sure either.

If you're considering changing it - it's good to understand how Elasticsearch treats arrays with an object type. There is information on that here: [https://www.elastic.co/guide/en/elasticsearch/reference/current/array.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/array.html)
