Hello,

I was able to get this working in python, but getting the following error when I try to nest math functions in an equation for a heat map lens:

Is this not supported? Thank you.

Hi @smchamberlin

I think what you are looking for is the `pick_min` function in Formula:

```auto
pick_min(ceil(count(kql='type.keyword="aha"') / 2), 2)

```
