Class RenderPassData

constructor

• new RenderPassData(indexRange: NumberRange | undefined, getxCoordinateCalculator: () => CoordinateCalculatorBase, getyCoordinateCalculator: () => CoordinateCalculatorBase, isVerticalChart: boolean, pointSeries?: IPointSeries, resamplingHash?: number, visibleIndices?: Int32Array): RenderPassData

• Creates an instance of RenderPassData

  Parameters

  • indexRange: NumberRange | undefined

    The min and max index to data-range currently visible on the SciChartSurface

  • getxCoordinateCalculator: () => CoordinateCalculatorBase

    A function to get the XAxis Coordinate Calculator, used to transform between pixel and data-coordinates

    • • (): CoordinateCalculatorBase

      • Returns CoordinateCalculatorBase

  • getyCoordinateCalculator: () => CoordinateCalculatorBase

    A function to get the YAxis Coordinate Calculator, used to transform between pixel and data-coordinates

    • • (): CoordinateCalculatorBase

      • Returns CoordinateCalculatorBase

  • isVerticalChart: boolean

    A flag indicating if the chart is currently vertically arranged (XAxis on the left, YAxis on the top/bottom)

  • Optional pointSeries: IPointSeries

    The point series

  • Optional resamplingHash: number

    The resampling hash value, used for caching

  • Optional visibleIndices: Int32Array

    When set, the authoritative list of data/storage row indices to process this pass. Label generation iterates this list instead of the contiguous indexRange window. Used by permuted views (e.g. a grid after a sort/filter) where the visible rows are non-contiguous in storage, so a single indexRange cannot express them. Undefined for the normal contiguous-window case (behaviour unchanged).

  Returns RenderPassData
