I have one requirement where I have to compare two metric and as per result I need to show up or down arrow. Below is the difinition of the Calculated field(Comparison), I want to display up arrow shape at the place of Good and Down arrow at the place of Bad. I tried using mark types but shape is getting applied to metric values and not to the Comparison metric. Multiple mark types option is also disabled.

if (max([Metric Value - Daily])- ([Previoud Day Value]))>0 then "Good" else "Bad" end

Thanks.
