has there been any consideration to removing the limitation of showing stacked graph, with one or more series using a customized series type? Or is there a workaround?
I have a chart showing unique users in each of several categories (stacked) per month. I'd really like to put the overall total unique users (which is lower than the sum of users in each category because users can be in multiple categories) as a line. The data table calculates this correctly, but if you try to set up the visualization, you first get both the "can't use column with Time Axis and multiple series" limitation (which is easy to work-around) but then I hit the "Can't Stack with Multiple Series Type" limitation.
