When creating a Box Plot graph in SSRS 2008, I have data in the dataset for
the high whisker, low whisker, low box, high box, median and Mean. The design
mode shows lines for Median and Mean within the boxes. However, when you go
to Preview mode, these lines do not exist. I don't see anything in any of the
chart properties to have these lines displayed.
