Update trend view to account for months where no data present

Evaluating this for aggregate report with day, week, month summarization. Not intended for a flat report where already aggregated numbers are brought into GS. Med sized effort as it needs to be supported across databases for all summarization options (day, week month etc) and performance also need to be considered. Do we replace missing data as 0, maintain trend, or add gap?
