Set the Position of the First Slice in a Current Default Pie Chart

You can specify the angle in a pie chart where the first pie slice starts. You can also change the direction of the slices so they appear clockwise or counter-clockwise.

The default starting position of the first slice is 90, which displays the first slice beginning at the 12 o'clock position. By default, the slices appear clockwise around the pie, so a starting position of 90 displays the first slice at the 12 o'clock position, a starting position of 180 displays the first slice at the 9 o'clock position, and so on.

Procedure

Select the pie chart object.
In the Properties pane, under General, beside the First Slice Angle property, enter the angle at which you want the first slice to appear.
To change the directions in which slices appear, change the Slice Direction property.
