We are trying to produce a trend graph for each month in a year returning the number of helpdesk calls for each category. For some categories, not all months will contain data (e.g. Feb may return a result while March had no incidents for this category).
Currently, when the graph is generated, any months in the category which have no data do not appear on the graph (e.g Jan, Feb, April). This leads to a misleading trend chart as the months with no data do not appear.
A crosstab report fills the empty cells with a 0, which is fine, but we need to represent these in chart format also.
