I am looking to create a forecast trendline based on previous data in timelion chart

Here is an example:  
 ![trendline](https://us1.discourse-cdn.com/elastic/original/3X/4/5/455e998fa280d49f286546df76ec25bb82c8ebed.jpeg)

Things I tried so far, with no luck:

- `mvavg()`
- `trend()` - close to what we want but not quite correct.

Please suggest the best course to achieve this. I am open to other visualizations as long as they can be added to a dashboard.
