Required two measure’s value across an axis in Line Chart based on slicer

Hi infantpowerbi ,

From your sample, I found that your error is casued by the dax highlighed below.

All =
CALCULATE (
    SUM ( 'Ratifications_Table'[District Short] ),
    FILTER (
        ALL ( Ratifications_Table[District Short] ),
        'Ratifications_Table'[District Short] = "ALL"
    )
)

As your Ratifications_Table[District Short] column is a string type, so it cannot be usefd with sum function so you will have error message.

I'm afraid that you should create the measure like below.

All_ =
CALCULATE (
    SUM ( 'Ratifications_Table'[Value] ),
    FILTER (
        ALLSELECTED ( Ratifications_Table ),
        'Ratifications_Table'[District Short] = "ALL Districts"
    )
)

Best  Regards,
