Difference between two values when one of the value is blank

Hi All,

I am a newbie to PBI. I have run into this issue with my matrix visual

Delta is calculated basically as the difference between Date 1 & Date 2 using DAX. If there is value in Date 1 (say 100) and a value in Date 2 (70) the Delta is 30. But like the table below sometimes the value in Date 1 is blank/empty/null and Date 2 has a value and vice verse . If that is the situation I need the Delta to show up as a negative and positive value respectively.
For example (see first 2 rows...3rd and 4th row are working as expected)

Date 1 Date 2 Delta
 100-100
100 100
906030
6090-30

 

Can someone help with this?
Thanks!

Hi @JudeVFrancis ,

Please refer to my pbix file to see if it helps you.

Create a column.

Delta_column = 'Table'[date 1]-'Table'[date 2]

Or a measure.

Delta_measure = MAX('Table'[date 1])-MAX('Table'[date 2])
