How to add percent difference 'column' to matrix

lbendlin Thanks for your contribution on this thread.

Hi BrazenTelephone ,

You can follow the steps below to get it:

1. Select the matrix visual and navigate to format pane. Toggle on the option "Column subtotals" and change Subtotal label as "Percent Change" just as shown in below screenshot

2. Create another new 5 measures to replace the orignal measures

New_AvgStep1_duration =
VAR _before =
    SUMX ( FILTER ( 'Table', [Period] = "BeforeChange" ), [AvgStep1_duration] )
VAR _after =
    SUMX ( FILTER ( 'Table', [Period] = "WithChange" ), [AvgStep1_duration] )
VAR _percent =
    DIVIDE ( _after - _before, _before )
RETURN
    IF ( ISINSCOPE ( 'Table'[Period] ), [AvgStep1_duration], _percent )

New_AvgStep2_duration =
VAR _before =
    SUMX ( FILTER ( 'Table', [Period] = "BeforeChange" ), [AvgStep2_duration] )
VAR _after =
    SUMX ( FILTER ( 'Table', [Period] = "WithChange" ), [AvgStep2_duration] )
VAR _percent =
    DIVIDE ( _after - _before, _before )
RETURN
    IF ( ISINSCOPE ( 'Table'[Period] ), [AvgStep2_duration], _percent )

New_AvgStep3_duration =
VAR _before =
    SUMX ( FILTER ( 'Table', [Period] = "BeforeChange" ), [AvgStep3_duration] )
VAR _after =
    SUMX ( FILTER ( 'Table', [Period] = "WithChange" ), [AvgStep3_duration] )
VAR _percent =
    DIVIDE ( _after - _before, _before )
RETURN
    IF ( ISINSCOPE ( 'Table'[Period] ), [AvgStep3_duration], _percent )

New_AvgStep4_duration =
VAR _before =
    SUMX ( FILTER ( 'Table', [Period] = "BeforeChange" ), [AvgStep4_duration] )
VAR _after =
    SUMX ( FILTER ( 'Table', [Period] = "WithChange" ), [AvgStep4_duration] )
VAR _percent =
    DIVIDE ( _after - _before, _before )
RETURN
    IF ( ISINSCOPE ( 'Table'[Period] ), [AvgStep4_duration], _percent )

New_AvgTotalProcess_duration =
VAR _before =
    SUMX ( FILTER ( 'Table', [Period] = "BeforeChange" ), [AvgTotalProcess_duration] )
VAR _after =
    SUMX ( FILTER ( 'Table', [Period] = "WithChange" ), [AvgTotalProcess_duration] )
VAR _percent =
    DIVIDE ( _after - _before, _before )
RETURN
    IF ( ISINSCOPE ( 'Table'[Period] ), [AvgTotalProcess_duration], _percent )

3. Replace the original measures with the above new measures

If the above one can't help you figure out, please provide some info just as suggested by lbendlin .
