Hello,

I am trying to visualize the average compression ratio. The values are ranging between -1 and 1. Sadly every value with fractional digits is not shown in the graph. Only values like -1, 0 or 1. I have played around with `precision()`, `multiply()` and also with the field definition. The last try was to multiply the numbers from application side but the problem with fractional digits still exists and I think it's the wrong approach ;).

Any help would be awesome! Thanks in advance.

This looks like a bug with Timelion. If the mapping of the `compressionRatio` field is correct in ES (`double`, `float`, `half_float`, `scaled_float`), then the `avg` function in Timelion should be able to handle it mathematically correctly.

Would you mind taking this information to the Kibana issue tracker? [https://github.com/elastic/kibana/issues](https://github.com/elastic/kibana/issues)

Thank you very much,  
-Tim
