Hey Rajinia,

you can create a scripted field, with the following painless script:

```auto
doc['APIName'].value + '_' + doc['APIVersionName'].value

```

That way you would get a field containing the name and the version in one field. If you use this you can now split up your buckets according to each name-version pair.

**Hint:** If this is a common use-case that you want to visualize over in your data, I would recommend you to add a field with that value at indexing time (e.g. modify your logstash config to add it, or whatever tool you are using). Adding it at indexing time will result in a way better performance, than scripted fields.

Cheers,  
Tim

Thanks, Tim

Is there any way I can get a graph only for a specific API like " where API name =='aa' or API name =='bb'

Yes, you can. Just add a filter on top of the visualization editor:

![screenshot-localhost-5601-2017-10-13-10-29-50-262](https://us1.discourse-cdn.com/elastic/original/3X/a/0/a048c1daf0374ee4c70d1888a4cff1e40f4a4d7a.png)

If you save that visualization, that filter will keep attached to it, meaning if you place it on a dashboard it will still just show the results for that API you filtered it for.
