Need Pie Chart Help

Hi,

I am trying to produce a special type of pie chart for work and I was wondering if anyone could help me. I am dealing with a process over the last 3 years and showing its comparative sizes over the 3 years (i.e. how it has gotten bigger). It has to do with handling applications so I would like to have one pie to say, for example, 10 applications in 2008, then the next to show 20 in 2009 and now 40 in 2010. Instead of having the three on one pie chart I have been asked to scale them to eachother i.e. doubling in size every time. I was wondering if this is possible with the pie charts on excel?

Thanks for your help in advance,
