firstRenderPassData
Get the renderPassData instance of this series.
Declaration
Objective-C

@property (nonatomic, strong, readonly, nullable) id<ISCISeriesRenderPassData> firstRenderPassData;
Swift

var firstRenderPassData: (any ISCISeriesRenderPassData)? { get }
Return Value

If it’s SCIStackedColumnRenderableSeries - returns its renderPassData. If it’s SCIVerticallyStackedColumnsCollection - returns the renderPassData of the first series from the collection.
firstDataSeries
Get the dataSeries instance of this series.
Declaration
Objective-C

@property (nonatomic, strong, readonly, nullable) id<ISCIDataSeries> firstDataSeries;
Swift

var firstDataSeries: (any ISCIDataSeries)? { get }
Return Value

If it’s SCIStackedColumnRenderableSeries - returns its dataSeries. If it’s SCIVerticallyStackedColumnsCollection - returns the dataSeries of the first series from the collection.
hasValidRenderPassData
Checks whether this stacked renderable series has valid render pass data.
Declaration
Objective-C

@property (nonatomic, readonly) BOOL hasValidRenderPassData;
Swift

var hasValidRenderPassData: Bool { get }


                        
                        
                        -isUpdateOfStackedRenderPassDataRequired:yCoordCalc:viewportSize:

Checks whether this stacked renderable series need to update its render pass data.

Declaration

Objective-C

- (BOOL)isUpdateOfStackedRenderPassDataRequired:
            (nonnull id<ISCICoordinateCalculator>)xCoordCalc
                                     yCoordCalc:
                                         (nonnull id<ISCICoordinateCalculator>)
                                             yCoordCalc
                                   viewportSize:(CGSize)viewportSize;

Swift

func isUpdate(ofStackedRenderPassDataRequired xCoordCalc: any ISCICoordinateCalculator, yCoordCalc: any ISCICoordinateCalculator, viewportSize: CGSize) -> Bool

Parameters

`xCoordCalc`	The current coordinate calculator for `X-Axis`.
`yCoordCalc`	The current coordinate calculator for `Y-Axis`.
`viewportSize`	The current viewport manager.

Return Value

If YES - update is required and -[SCIStackedSeriesCollectionBase updateStackedRenderPassDataValuesWithXAxis:yAxis:] should be called.


                        
                        
                        -tryAddSeriesToLegendDataSource:

When overridden in derived classes, should add all needed ISCIRenderableSeries into legend data source.

Declaration

Objective-C

- (void)tryAddSeriesToLegendDataSource:
    (nonnull NSMutableArray<id<ISCIRenderableSeries>> *)legendDataSource;

Swift

func tryAdd(toLegendDataSource legendDataSource: NSMutableArray)
