One way to do it is to have 2 series, one for each sheet, and make a Stacked
bar chart.

The only problem is that you don't get to see the total when adding labels
to the series.

I want to add data from 2 different sheets within the same work book added
together. ie say data from Sheet1 B1 + Sheet 3 B1 as source data for the same
bar on the chart. Can this be done direct or do I have to add them together
first then use that as the source data.
I have tried typically the following: Sheet1!$B$1+Sheet3!$b$1 and several
variations of this without success.
