Show zero on Line chart where no data for date

Anonymous 

Ok, here is a true and tested way:

Create a measure along the lines of:

Cutoff = 
VAR _MaxDataDate = CALCULATE(MAX('Audits'[ShiftDate]), ALL('Audits'))
RETURN
IF(MAX('Calendar'[Date]) <= _MaxDataDate, 1) 

Now select the visual and add this measure to the "Filters on this visual" in the filter pane and set the value to 1. 

Use the proven [AuditCount] measure in the visual:

PaulDBrown as a follow-up to my reply yesterday, I came up with a different solution.  As well as yours worked, it did not work for what I need to show.  What I ended up doing is adding two calculated columns to my Audit Table.

CountO = If(Audits[Shift]="O",1,0)
CountB = If(Audits[Shift]="B",1,0)

and added them to my visual.  I got the chart and the matrix to display with zeros as I wanted and no unwanted dates.

Thank you for putting up with me.  🙂
