Web Chart - Plot Total Column as well

I have a requirement of producing a report that has a date down the side, and then each plant within a country across the top.

ie

Plant1 Plant2 Plant3... Total For All Plants

Date

date1

date2

Using the web charting tool, is it possible to plot the data for each plant, and also the Total for all plants on the same chart? I have found that the total normally doesn't plot on Web reports (which in most cases is good), however I thought there might be a setting that I was missing.

I am using BW3.5

Thanks in advance for any assistance.
