Comparing between different filters on the same data
Say I have data like this:
| Date | Account | Statistic | Value |
| 30/06/2017 | 1 | Alpha | 0.85 |
| 30/06/2017 | 2 | Alpha | 0.34 |
| 30/06/2017 | 1 | Beta | 0.52 |
| 30/06/2017 | 2 | Beta | 0.29 |
| 30/06/2017 | 1 | Gamma | 0.14 |
| 30/06/2017 | 2 | Gamma | 0.25 |
| 31/07/2017 | 1 | Alpha | 0.35 |
| 31/07/2017 | 2 | Alpha | 0.23 |
| 31/07/2017 | 1 | Beta | 0.51 |
| 31/07/2017 | 2 | Beta | 0.26 |
| 31/07/2017 | 1 | Gamma | 0.16 |
| 31/07/2017 | 2 | Gamma | 0.90 |
| 31/08/2017 | 1 | Alpha | 0.88 |
| 31/08/2017 | 2 | Alpha | 0.20 |
| 31/08/2017 | 1 | Beta | 0.76 |
| 31/08/2017 | 2 | Beta | 0.79 |
| 31/08/2017 | 1 | Gamma | 0.83 |
| 31/08/2017 | 2 | Gamma | 0.66 |
Now imagine I have two bar charts (one per Account), with Date on X and Value on Y, and the different Statistics as different bars.
[In reality there are a lot more Accounts, and there are two slicers to select the two Accounts we want to compare.]
How can I get a third chart that shows the Value difference between the two, again per Date and Statistic?
I started by creating a duplicate of the dataset and now want to do something like https://community.powerbi.com/t5/Desktop/How-to-calculate-difference-after-different-filter-settings/td-p/153317 - but there is no sensible way to relate the table with its duplicate.
There must a way to do this surely?
Hi olik,
You can try the below method as well!!! FYI, I have the data that you have provided for this purpose
The Following are the steps.
1. Have 2 copies of your data (namely Table1 and Table2)
2. Join the tables based on Date Column
3. Create the following 2 measures
In Table1
Measure 1 = CALCULATE(SUM(Table1[Value]), FILTER(Table1, Table1[Account] = SELECTEDVALUE(Table1[Account])))
In Table2
Measure 2 = CALCULATE(SUM(Table2[Value]), FILTER(Table2, Table2[Account] = SELECTEDVALUE(Table2[Account])))
Create another measure to find the difference between the measures
Measure = [Measure 1] - [Measure 2]
Relationship, more likely to look like (not necessarily have to be same)
Relationship between tables through a bridge table
My Output looked as shown below
Output
As you change the accounts in your slicer, you value changes correspondingly....
Hope this helps you get what you needed!!!

Thanks a lot! I used your suggestion and made the formula even easier:
Result = SUM(Table1[Value]) - CALCULATE(SUM(Table1[Value]), FILTER(ALL(Table1[Account]),Table1[Account] = SELECTEDVALUE(Table2[Account])))
That way I only need one measure, and technically I don't even need the full duplicate table... Just another list of accounts would do!
Do you see any issues with my approach? Still very new to the whole DAX coding!

I think I have found a way, using an additional measure based on SELECTEDVALUE parameters and then defined as such:
CALCULATE
(
AVERAGE(Table1[Value]),
FILTER(
ALL(Table1[Account]),
[Account]=Table2[Selected Account]
)
)Surely that can't be the best way though?
