ISCIPieChartSurface
@protocol ISCIPieChartSurface <ISCIChartSurfaceBase, ISCIView>Defines the interface to the SCIPieChartSurface, which contains a single SCIPieChartRenderSurface viewport
for rendering multiple ISCIPieRenderableSeries which may have a ISCIPieSegment
in the appropriate SCIPieSegmentCollection as a source.
The SCIPieChartSurface may have zero or many ISCIPieChartModifier to enable interaction with the chart.

ISCIPieChartModifier-
Gets or sets size of hole for first donut series. Hole size in points
Declaration
Objective-C
@property (nonatomic) float holeRadius;Swift
var holeRadius: Float { get set } -
Gets or sets the SpacingMode to use for computation of radius of the hole, which is used only for SCIDonutRenderableSeries E.g. the default of Absolute requires that the spacing value is in pixels. The value of Relative requires relative spacing value
See
SCISizingModeDeclaration
Objective-C
@property (nonatomic) SCISizingMode holeRadiusSizingMode;Swift
var holeRadiusSizingMode: SCISizingMode { get set } -
Gets or sets the value which indicates spacing between series.
Declaration
Objective-C
@property (nonatomic) float seriesSpacing;Swift
var seriesSpacing: Float { get set } -
Gets or sets the SpacingMode to use for computation of spacing. E.g. the default of Absolute requires that the spacing value is in pixels. The value of Relative requires that the spacing value is a double value from 0.0 to 1.0.
