SectorSpacing

is an option to PieChart and related functions that specifies radial spacing of sectors.

Details

SectorSpacing determines the spacing between concentric sectors for different datasets. It also determines the default popout distance when sectors are clicked.
The following settings can be given for SectorSpacing:

	Automatic	automatically determine sector spacing
	None	use no sector spacing
	Tiny,Small,Medium,Large	use preset sector spacings
	s	use sector spacing s
	{s_p,s_c}	use popout spacing s_p and concentric spacing s_c

In PieChart and PieChart3D, s_i is measured as a fraction of the radial width of sectors.
In SectorChart and SectorChart3D, s_i is in the same units as the radial component of data.

Examples

Control the spacing between annular regions:

Wolfram Language code: Table[PieChart[{{1, 1, 1}, {1, 2, 3}}, SectorSpacing -> s], {s, {Tiny, Small, Medium}}]

For 3D pie charts:

Wolfram Language code: Table[PieChart3D[{{1, 1, 1}, {1, 2, 3}}, SectorSpacing -> s], {s, {Tiny, Small, Medium}}]
