How to create a metric from a filter

[Mylann]

Hello everyone,

I created a dashboard on Looker to collect the clicks on different items on my website. I found the solution on scorecard to get the number of clicks by user. (for example: when I want to track all of the popup openings, I selected the metric: total number of users and I added my filter on the event name: ouverture_popup_inscription).

But I need to calculate the ratio between different data. So I want have the data in a specific metric.
