Custom tooltip in Packed Bubble (Bubble Chart) viz

[elinvangbo]

Hi! 

While waiting for the functionality of making totally custom tooltips in Looker, I’ve tried to follow this article to display two values in my Packed Bubble visualization. I can get the values the way I want to but for some reason it doesn’t work on the specific visualization. It works when I use other visualizations like bar- and line chart. Does anyone know if it’s possible to customise the tooltip shown in the Bubble - viz? Would be really helpful since I’m already using two measures to create the visual, one for colour and one for size.

Thank you,

Elin
