Pareto Chart

Hi,

I have created a Pareto chart (see attached file).

Now I need to include the Country in the chart. So what (I think) I'm looking for is a Stacked column chart which shows one column for each SalesPerson, which will be stacked showing the breakdown per country. I still need to have the Cumulative % displayed as in the attached file as a Line chart.

Any ideas on how this can be done?
