## 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... - but there is no sensible way to relate the table with its duplicate.

There must a way to do this surely?

## Re: Comparing between different filters on the same data

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!!!

## Re: Comparing between different filters on the same data

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!

## Re: Comparing between different filters on the same data

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?

Hi @olik,

I think the new DAX that you have written should be good enough to get the difference
