When you change the starting angle or the direction, only current versions of the software show the changed values. Older versions of the software display the same document using the default values: Always counterclockwise direction and a starting value of 90 degrees (2-D pie charts) or 0 degrees (3-D pie charts).
当您更改起始角度或方向时，只有软件的当前版本会显示更改值。软件的旧版本会使用默认值来显示相同的文档：总是显示逆时针方向且起始角度为 90 度（二维饼图）或 0 度（三维饼图）。
