Hi ilui ,

Based on your description, you can create this measure:

Forecast Diff =
VAR _max =
    CALCULATE ( MAX ( 'Table'[Snapshot Date] ), ALLSELECTED ( 'Table' ) )
VAR _min =
    CALCULATE ( MIN ( 'Table'[Snapshot Date] ), ALLSELECTED ( 'Table' ) )
VAR _maxsum =
    CALCULATE ( SUM ( 'Table'[Forecast] ), 'Table'[Snapshot Date] = _max )
VAR _minsum =
    CALCULATE ( SUM ( 'Table'[Forecast] ), 'Table'[Snapshot Date] = _min )
RETURN
    _maxsum - _minsum

To achieve the same visual, create two matrix to use visual overlay:

ilui , You can use day vs last day and take a diff. Use date table.

Example

Last Day Non Continuous = CALCULATE([sales],filter(ALLSELECTED('Date'),'Date'[Date] =MAXX(FILTER(ALLSELECTED('Date'),'Date'[Date]<max('Date'[Date])),'Date'[Date])))
Day behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Day))
Diff COlumn = datediff(maxx(filter(Table,Table[Date]<earlier(Table[Date]) && Table[Numberf]= earlier(Table[Numberf])  ),Table[Date]) ,Table[Date],Day)

This Day = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])))
Last Day = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])-1))
Last Day = CALCULATE(sum('order'[Qty]), previousday('Date'[Date]))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
