I am having little problem displaying Reference lines parallel to Y axis.
Here is the description:
I have a filed "Month" which holds data for 3 years (in format like Jan-10 through Dec-10,Jan-09 through Dec-09,Jan-11-Dec-11).I want to plot expression (say Sum(Sales)) against this dimension and it is working all fine. Now I want to have reference lines at the end of each year i.e. on Dec-09, and Dec-10 . The "Month" field in not a calculated dimension and is directly from DB. I have attched the sample layout below.Need your suggestions.
