Serial Chart: Display Parsed Date Categories with No Values

[BrianK_1233]

Hello,

Is there a way to display a zero value for categories that are parsed dates in a serial chart if there are no records that fit? For example, I want the green (lower) line in the chart below to be at zero for the months of January, May, and July, rather than just show nothing or carry the line across the month.

Thank you for your help!
