hi All,

I am trying to show hourly average in a Kibana Visualization. I referred to the example in this link -[Hourly Average over 24 hours](https://discuss.elastic.co/t/hourly-average-over-24-hours/201445/2).

However, when I select Histogram option, I get an error saying "The index pattern mypattern\* does not contain any of the following compatible field types: number". Do I need a custom script field to be added? I already have a timestamp field defined as date which I am using for time slicing.

I am using 7.5.2 of Kibana. Let me know if you need any further info.

Thanks!

Yes, you need to create a scripted field containing the hour of the day for this.

Go to Management \> Index patterns \> _your index pattern_ \> scripted fields

and add a scripted field of type number like with this script:  
`doc['timestamp'].value.getHour()`

thanks @flash1293. I am able to see it now. Looks like scripted fields are only available in Lens from 7.6 onwards. So will stick to regular histograms for now.

Thanks!
