Cumulative datas with slicer

Hi Anonymous 
Based on my understanding, I'm answering this question. It might be correct/wrong. Pls follow the steps.

1) Create Planned date calculated column for cumulative counts. use the below measure

Cumulative Planned = 
CALCULATE(
    COUNTROWS('Table'),
    FILTER(
        ALL('Table'),
        'Table'[Planed Date] <= EARLIER('Table'[Planed Date])
    )
)

2) Create Actual date calculated column for cumulative counts. use the below measure 

Cumulative Actual = 
CALCULATE(
    COUNTROWS('Table'),
    FILTER(
        ALL('Table'),
        'Table'[Actual Date] <= EARLIER('Table'[Actual Date])
    )
)

Then use this measures as shown in below snapshots.
