Clustered stacked column
 

I'd like to create something like this:

http://peltiertech.com/Excel/ChartsH...sterStack.html

I have the data in the following format:

Row 1 Dates
Row 2 Planned - company a
Row 3 Planned - Company b
Row 4 Actual - Company A
Row 5 Actual - Company B
I want to have a stacked column including Planned values with both companies
stacked, and another stacked column for actual values for both companies.
How would I do this?

Thanks
