Create a doughnut chart with the first series.
Select the second data column and copy it.
Click the chart end select Paste Special. Specify that you want to add a new series.
Select the new series and change the chart type to Pie chart.
Note that the doughnut chart and the pie chart are actually the same size, the pie chart only shows in the "hole" of the doughnut chart (i.e. the doughnut chart sits on top of the pie).
Select the pie chart and add labels with the series name. Delete all but one label and drag that label towards the center.
Select the doughnut chart and add labels with the series name. Delete all but one label and drag it into position.
(I'm feeling sick describing how to do that :)) )
That's all I did in the previously attached file.
Oh: I added borders to the series, so they don't blend into each other!!
