Power BI Grand Total Percentage By Month

[Anonymous]

Good day,

I do have a scenario like this , Total Customers are: 4.

2 of them were paid and rest of the 2 Customers have not paid, which is 50 percent of Customers have not paid.

One of the Unpaid Customers supposed to pay in June, 2018 and another Customers should have paid in Oct, 2018. They are "Overdue" now.. 

When you see unpaid Customers on the Power BI bar chart....

X - Axis is Month Name

Y - Axis is Percentage. 

On Y -Axis,  June month should show 25% and Oct Month shouid show 25%, BASICALLY WE HAVE TO SPLIT 50% between 2 Customers (OR UNPAID CUSTOMERS).

Please suggest suitable DAX for that

Thank you so much in advance
