I have 2 date-type:

- "timestamp\_pickup\_at" : "2021-09-06T04:10:28.070Z",
- "timestamp\_hangup\_at" : "2021-09-06T04:10:36.022Z"

I want to visualize that as a conccurency date histogram.  
I refer to this [topic](https://discuss.elastic.co/t/display-concurrency-in-data-on-kibana/26006/13) but not work.

This is my INPUT JSON:

Hello @hoaf13

Welcome to our community!

It seems that the script that you copied is pretty old. Can you try with this updated one?

```auto
"script": "def start = doc['start_date'].value; def duration = doc['duration'].value*1000*1000; def l = []; for (long i = 0; i < duration; i += 60000) { l.add(start + i); }; return l;",

```

Cheers  
Sébastien
