KPI Matrix 3.1.1 KPI Indicator - non tabular data

[my_microsoftacc]

I was studying the Pbix sample file but still couldn't figure out how to create KPI Indicator for my case.

So in the sample file, the data is in the tabular form like pic below so it's very easy to calculate the variance and hence, the KPI Index. (calc variance = actual value/target - 1)

My data, however, looks like this.

So the Actual and Budget for Vol, Rev, NB here is the calculated fields. PowerBi then calculates the KPI comparing Actual vs Budget "Actual vs Budget%". So how can I create a KPI Indicator for the "Actual vs Budget%" field indicating negative = red color and positive = green color?

Thank you.
