Cummulative vs individual in a line chart

Hi AmazingRandom ,

According to your describe, here are my test data:

1.Create a measure

Running total = 
VAR X = CALCULATE(
        SUM('Table'[value1]),
        FILTER(ALL('Table'),'Table'[Date]<=MAX('Table'[Date])))
VAR Y = CALCULATE(
        SUM('Table'[value2]),
        FILTER(ALL('Table'),'Table'[Date]<=MAX('Table'[Date])))
VAR Z = CALCULATE(
        SUM('Table'[value3]),
        FILTER(ALL('Table'),'Table'[Date]<=MAX('Table'[Date])))
RETURN X+Y+Z

2.Create a line chart

3.Create a slicer and use data column as value

4.Final output
