Creating a running total percent in line and stacked column chart

[ptepichin]

I'm trying to create a running percentage total where the percentage gets added as such. 

I have figured out how to calculate the percentage but need to figure out how to do an incremental addition: 

Total = DIVIDE( CALCULATE(COUNT(Exceptions[LabDef])), CALCULATE(DISTINCTCOUNT(Exceptions[Label]), ALL(Exceptions[xid])))

Any help would be appreciated.
