Rolling 12m for each date

[Halleri]

Hi, I got a date table [DateTable] and a table of sales [Sales]. I've successfullt created a rolling 12m for sales:

RoSales 12m =
VAR minDate =
    DATE ( YEAR ( MAX ( DateTable[Date] ) ); MONTH ( MAX ( DateTable[Date] ) ) - 12; DAY ( MAX ( DateTable[Date] ) ) )
RETURN
    CALCULATE (
        SUM ( Sales[Sales] );
        FILTER (
            DateTable;
            DateTable[Date] > minDate
                && DateTable[Date] <= MAX ( DateTable[Date] )
        )
    )

What I want to do, and failed repeatedly to, is to get a chart with dates on the X-axis and the Sales for the last 12 months at each date on the Y-axis.
Example if in table: 

|____Date_______|_Rolling 12__|
| 10 Aug 2017    | 100K           |
| 11 Aug 2017    | 101K           |
| 12 Aug 2017    | 108K           |
| 13 Aug 2017    | 107K           |

All my attempts results in the measure taking in the context of the date and plots out the sum for that date, when I really want the sum of the whole last year with the date as end point. Is this possible?

Cheers!
