Using Measure Name as Dynamic Title

lbendlin, xifeng_L 
Xifeng your solution works in Matrix. When tying to apply it in a line chart with multiple measures in y-axis and Date in x-axis the same continues. When filtering one measure (one line) it works but when all lines are visible it doesn't. 
Also tried below but same result.

VAR _Selected =
IF(SELECTEDMEASURENAME() = "Tickets", SELECTEDMEASURE(),
BLANK())

VAR _Selected2 =
IF(SELECTEDMEASURENAME() = "Tickets", "Tickets",
BLANK())

Any ideas how to make it work with field parameters? Tried below:

Tickets = {
    ("Tickets", NAMEOF('DimMeasures'[Tickets]), 0),
    ("Tickets Cancelled", NAMEOF('DimMeasures'[Tickets cancelled]), 1),
    ("Tickets not on time", NAMEOF('DimMeasures'[Tickets not on time]), 2),
    ("Tickets on time", NAMEOF('DimMeasures'[Tickets on time]), 3)
}

However when choosing it with 

SELECTEDVALUE(Tickets[Parameter])

 Power BI gives the error:

Couldn't load the data for this visual
MdxScript(Model) (303, 1) Calculation error in measure 'DimMeasures'[Measure Title_]: Column [Parameter] is part of composite key, but not all columns of the composite key are included in the expression or its dependent expression.
