Timelion ignores fractional digits

Elastic Stack Kibana
1

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

Thank you very much,
-Tim
