Line chart customisation

Hi Fali324 

Certainly, please check the following changes:

Change the x-asix Table:

X-axis =
UNION (
    VALUES ( 'Table'[Project] ),
    SELECTCOLUMNS (
        VALUES ( 'Table'[Project] ),
        "Project", "Select-" & 'Table'[Project]
    )
)

And so do the Measure:

MEASURE =
VAR _Slicer =
    VALUES ( Slicer[Project] )
VAR _length =
    MAXX ( ADDCOLUMNS ( 'X-axis', "Length", LEN ( 'X-axis'[Project] ) ), [Length] ) - 7
VAR _CurrentPro =
    SELECTEDVALUE ( 'X-axis'[Project] )
RETURN
    IF (
        _CurrentPro IN VALUES ( 'Table'[Project] ),
        CALCULATE ( SUM ( 'Table'[Duraction] ), 'Table'[Project] = _CurrentPro ),
        IF (
            ISFILTERED ( Slicer[Project] ),
            CALCULATE (
                SUM ( 'Table'[Duraction] ),
                'Table'[Project]
                    IN _Slicer
                        && 'Table'[Project] = MID ( SELECTEDVALUE ( 'X-axis'[Project] ), 8, _length )
            )
        )
    )

Then select all the selections of the Slicer and Open all the lines of the selections with "Select-":

You can alse change the Color:

The result is as follow:
