Graph Values and Zero-Values Only Within Date Range

The “+0” will make your measure always return a value. This was you’ll never get blanks. What I think you want is to maintain a blank value if -there aren’t any sales before the last date in the period you’re analyzing, nor sales after.

With a setup like: 

If you create this measure:

Sale Amount =
VAR SaleAmountInPeriod =
    SUM ( Sales[Sale] )
VAR LastDateInPeriod =
    MAX ( 'Calendar'[DateTime] )
VAR ExistLaterSales =
    NOT ( ISEMPTY ( FILTER ( ALL ( Sales ); Sales[DateTime] > LastDateInPeriod ) ) )
VAR ExistEarlierSales =
    NOT ( ISEMPTY ( FILTER ( ALL ( Sales ); Sales[DateTime] < LastDateInPeriod ) ) )
RETURN
    IF (
        NOT ( ISBLANK ( SaleAmountInPeriod ) );
        SaleAmountInPeriod;
        IF ( AND ( ExistLaterSales; ExistEarlierSales ); 0 )
    )

And, if you have Sales entries like:

Sale table with hourly records
With out any filtering, you'll get this when you create the graph:

If you than apply a filter to only show November, you get this:
