Doughnut graph query

[Jo]

Can anyone tell me how I can create a doughnut graph using the graph function
and get the lines to be straight? If I create a pie graph the lines are
perfectly straight however if I change it to a doughnut graphs the lines are
all wobbly. Why does this happen and can I fix it?

Which version of PowerPoint do you use?
Do you change anything else (lines, size, color)?

I am using Powerpoint 2003 and I'm not changing anything on the graph. Even
if I make one from scratch it does this.
