Use to specify the slice order, slice starting angle, and the minimum category size for separate slices. After creating a pie chart, you can also:
Order slices by
Default: Choose to accept the default slice order. For counts data, the slice order is increasing value for numeric and date/time data; or alphabetical for text data. For summarized data, the default slice order is the order in which the categories appear in the worksheet. To use a different order for text data, see Ordering text categories.
Increasing volume: Choose to order slices from smallest to largest.
Decreasing volume: Choose to order slices from largest to smallest.
Start angle:
Type the starting angle in degrees for the slices. By default, slices
start at 90
Combine slices of this percent or less: Type a minimum percentage for separate slices. Categories less than this percentage are grouped into a slice named Other, which is always placed last.
