I have a log of various event  
I need to find the ratio of "good events" from "bad events". I want to graph it over time.

For the "vertical axis formula", I need something like  
`count(eventName=="bad) / count(eventName=='good') `

How can I do it ? while I can create a global Filter by eventName, I can't find a way to create it inside the axis formula.

You may find explanation in "Common formulas". `kql` can be used in Formula.

```auto
count(kql='eventName: true ')/count(kql='eventName: false ')

```
