Add measure to Line y-axis for Line and Clustered Column Chart - Not showing data

Hi All,

I have the below Line and Clustered Column Chart Visual.

What I want to do is add a line y-axis using a measure but when I implement it it doesn't show on the visual.

The blue line in the below visual is what I want to create, I have listed all the measures I am using below

Measures for x-Axis

I'm just using the date from a date table I created, I have relationships  created for the dates in the below measures with this the date column in the date table

Measures for Column y-Axis

Awaiting Approval Cumulative Revenue = 

VAR MaxDate = MAX(Data[Date to use AwaitingApproval_Approved])

RETURN
    CALCULATE(
        SUM(Data[Revenue]),
        FILTER(
            ALL(Data),
            Data[Label to use AwaitingApproval_Approved] <> "Approved" &&
            Data[Date to use AwaitingApproval_Approved] <= MaxDate &&
            Data[AwaitingApproval_Approved] <> BLANK()
        )
    )

Approved = 

VAR MaxDate = MAX(Data[Date to use AwaitingApproval_Approved])

RETURN
    CALCULATE(
        SUM(Data[Revenue]),
        FILTER(
            ALL(Data),
            Data[Label to use AwaitingApproval_Approved] = "Approved" &&
            Data[Date to use AwaitingApproval_Approved] <= MaxDocDate &&
            Data[Date to use AwaitingApproval_Approved] <> BLANK()
        )
    )

Measure I'm using for Line Y-Axis that is not working

Future Approval for Products with AwaitingApproval_Cumulative Revenue = 

VAR MaxDate = MAX(Data[Date to use AwaitingApproval_Approved Visual])

RETURN
    CALCULATE(
        SUM(Data[Revenue]),
        FILTER(
            ALL(Data),
            Data[Label to use DoC_CertIssued Visual] <> "Approved" &&
            Data[Future Approval Dates] <= MaxDate &&
            Data[Future Approval Dates]  <> BLANK()),
            USERELATIONSHIP(Future Approval Dates],'Date Table'[Date])
        )

Everything is working except the Measure I'm using for Line Y-Axis, please help!
