Cumulative Total with Legends

[Anonymous]

Hello everyone,

Thanks for reading this post. Just wondering how can I show my cumulative stacked chart with legends. 

Here is my formula for cumulative total.

CumulativeTotal = CALCULATE(DISTINCTCOUNT('maintable'[mainid]),

FILTER ( ALLSELECTED ('maintable'), 'maintable'[Date] <= MAX ('maintable'[Date])))

If I wanted to have legends in this formula, how will I put include it?

Thanks
