I have a chart, with a date (settlement date) as dimension. and as expression the number of cases settled by that date (for example Jan 2016). The dimension is a group created with years, months, weeks.
I need to show all the number of cases that settled by Jan '16 / all cases that were closed in Jan '16
My problem is that all cases closed means all cases closed even the ones not settled (with date of settlement null to understand)
