Handling Multiple dates inside visual

So I have a table with multiple dates: 'Opened Date', 'Closed Date', 'Maintenance Start Date', 'Maintenance End Date'.

Other than dates I have also 'Total Approved'.

I have created a calendar table and created inactive relationships to be able to handle all dates using USERELATIONSHIP.

Currently I have 2 Measures:

Total Approved by Maintenance End Date = 
CALCULATE(
    SUM ( Table[TOTAL APPROVED] ),
    USERELATIONSHIP(
        dCalendar[Date],
        Table[MAINTENANCE END DATE]
    )
)

Total Approved by Closed Date = 
CALCULATE(
    SUM ( Table[TOTAL APPROVED] ),
    USERELATIONSHIP(
        dCalendar[Date],
        Table[CLOSED DATE]
    )
)

 I can see each one separately in a column chart, but I wanted to have a consolidated view. I wanted to create a column chart which has Closed Date as X-axis, Total Approved as Values, and Maintenance End Date as Legend. Something like I did in this Excel below (but if I could group by Month, instead of Year, it'd be even better).
