Vertical lines in a graph

Hi,

According to your description, i think your requirement can not be reached completely, but i have a workaround:

Please choose Line and Clustered Column Chart visual.

Then try this measure:

Measure = 
IF (
    DISTINCTCOUNT ( 'Slicer Table'[Date] ) = BLANK ()
        || DISTINCTCOUNT ( 'Slicer Table'[Date] )
            = CALCULATE ( DISTINCTCOUNT ( 'Slicer Table'[Date] ), ALL ( 'Slicer Table' ) ),
    BLANK (),
    IF (
        MIN ( 'Table'[Date] ) IN DISTINCT ( 'Slicer Table'[Date] ),
        MAXX (
            CALCULATETABLE ( DISTINCT ( 'Table'[Date] ), ALLSELECTED ( 'Table'[Date] ) ),
            CALCULATE ( SUM ( 'Table'[Sales] ) )
        )
    )
)

Create another seperate slicer table:

Slicer Table = SELECTCOLUMNS('Table',"Date",'Table'[Date])

When choose one or more dates you want in slicer, the result shows:

You can also use another custom visual called Multiple Axes Chart - XViz :

The result shows:

Hope this helps.
