Hi,

I store some **video** information in ElasticSearch. And more particularly, the time (of the video) when a user begin to see the video and the time until he stop the video. Like in the next picture:

 ![capt](https://us1.discourse-cdn.com/elastic/original/3X/d/5/d5d520f19e7e889a5d04a959b3a7acdd13ee2184.png)

I would like to count how much user see the video on each second of this video. In the other world, i would like an output like this:

```auto
 [
    {
        time: 0,
        count: 100
    }, {
        time: 1,
        count: 70
    }, {
        ...
    }, {
        time: 360,
        count: 30
    }
]

```

To make this we "just" must to see if "time" is between "start" and "start + view\_time" and to have the total time we just must to make "max(start+view\_time)".  
I don't know if it's natively possible... Or if it exist something to have "view count" second per second.

Thanks to you,
