Methods

applyTheme

delete

  • delete(): void
  • Deletes native (WebAssembly) memory used by this type, after which it cannot be used.

    remarks

    Call .delete() before finishing with the object to ensure that WebAssmembly memory leaks do not occur.

    Returns void

Protected getAllSeries

  • Gets all series on the parent surface.

    remarks

    This function allows mocking in tests

    Returns IRenderableSeries[]

Protected growBy

  • Grows the Axis by a fraction around the mouse point

    Parameters

    • mousePoint: Point

      the X,Y location of the mouse at the time of the operation

    • axis: AxisBase2D

      the Axis to grow or shrink

    • fraction: number

      the fraction, e.g. 0.1 grows the axis by 10%

    Returns void
