Hi,

I am storing objects in JSON documents looking like this:
```
{
  "events": [
    {
      "date": "2019-03-20T18:30:00",
      "event-type": "SOME_TYPE"
    },
    {
      "date": "2019-02-07T18:00:00",
      "event-type": "ANOTHER_TYPE"
    }
  ]
}
```
First, I set the mapping of the relevant index to have `events` as a nested type. Then, I plug in Kibana and I would like to build a graph, from 0h to 24h on the X axis, showing the count of events spread in dots. I do not understand how I can do that. I would do that using some homemade backend but since Kibana exists I thought it would be a nice use case.

Is it possible to achieve what I want using my current data structure and Kibana, or should I:
- forget about Kibana for that purpose
- change my data structure to duplicate the time in another property

Thanks :slight_smile:
