      dpr: number,
      style: SeriesStyle,

  • items: readonly DrawItem[]
  • toY: (v: number) => number
  • barSpacing: number
  • dpr: number

  Returns void

extents

• extents(bar: Bar, style: SeriesStyle): { max: number; min: number }

• Min/max price contribution of one bar to autoscale.

  Parameters

  • bar: Bar
  • style: SeriesStyle

  Returns { max: number; min: number }
