Show value changes in percentage for Multiple value cards comparison

[levi-hoang-CLV]

So In this case, I have two table calculation with values : 10% (KPI) and 12 %. I want the visualization type as Multiple value visualization and it will show value change comparision as percentage (2%). But I can not find any option in Lookml dashboard or visualization to get this.

The multiple value visualization will only display measures. It looks like your 10% KPI table calculation is a dimension. To trick Looker into making it a measure, reference a measure in the calculation in a way that won't affect the result. 

For example, if your current KPI definition is "0.10", change it to something like "0.10 +${measure_name}*0". The measure that you reference doesn't matter since you're multiplying it by zero anyways.
