Two questions:
1. If I don't want the legend to show, and instead just have data labels, I
end up with a big empty space on the right (initially for the legend). How do
I center the graph to make use of the space? Otherwise, how may I crop out
the empty space?
2. When I copy the chart object and paste into Powerpoint, the Leader Lines
leading the data labels into the pie chart disappears. Is there a way to
preserve those lines?

Thanks!
