Methods

dispose

  • Permanently destroy the component.

    To fully allow Garbage-Collection to free the resources used by the component, make sure to remove any references to the component and its children in application code.

    let chart = ...ChartXY()
    let axisX = chart.getDefaultAxisX()
    // Dispose Chart, and remove all references so that they can be garbage-collected.
    chart.dispose()
    chart = undefined
    axisX = undefined

    Returns

    Object itself for fluent interface

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>

getAutoFitStrategy

  • Get is auto-fit enabled. Affects logic of automatic fitting of Cursors ResultTable to the screen.

    Returns

    Boolean flag whether auto-fit is enabled

    Returns boolean

getPointMarkerVisible

  • Get point marker visible or not.

    Returns

    Boolean.

    Returns boolean

getResultTableVisible

  • Get result table visible or not.

    Returns

    Boolean.

    Returns boolean

getVisible

  • Get element visibility.

    Returns

    true when element is set to be visible and false otherwise.

    Returns boolean

isDisposed

  • Check whether the object is disposed. Disposed objects should not be used!

    Returns

    true if object is disposed.

    Returns boolean

offDispose

  • Remove event listener from dispose event.

    Returns

    True if the listener is successfully removed and false if it is not found

    Parameters

    • token: Token

      Token of event listener which has to be removed

    Returns boolean

onDispose

  • Subscribe to onDispose event. This event is triggered whenever the object is disposed.

    A component can only be disposed by the end user, by calling the dispose method on the component or the component which owns it.

     // Example usage

    Dashboard.onDispose(() => {
      console.log('Dashboard was disposed')
    })

    Dashboard.dispose()

    Returns

    Token of subscription

    Parameters

    • handler: (() => unknown)

      Handler function for event

        • (): unknown

        • Returns unknown

    Returns Token

setAutoFitStrategy

  • Set auto-fit strategy of Cursor. Affects logic of automatic fitting of Cursors ResultTable to the screen.

    Returns

    Object itself for fluent interface

    Parameters

    • Optional autoFitStrategy: AutoFitStrategyFactory<ResultTableBackgroundType>

      AutoFitStrategy factory or undefined to disable auto-fitting

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>

setPointMarker

  • Mutator function for Cursors PointMarker. PointMarker is a visual that is displayed at the Cursors position

    Returns

    Object itself for fluent interface

    Parameters

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>

setPointMarkerVisible

  • Set point marker visible or not.

    Returns

    Object itself.

    Parameters

    • visible: boolean

      Point marker visible?

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>

Abstract setPosition

  • Set cursor position.

    Returns

    Object itself.

    Parameters

    • Rest ...cursorPositions: CursorPositionType[]

      Abstract interface that describes cursor position. Actual type depends on type of cursor (XY, 3D, Polar, etc...)

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>

setResultTable

  • Mutator function for Cursors ResultTable. ResultTable is a visual that displays currently pointed data next to its location

    Returns

    Object itself for fluent interface

    Parameters

    • mutator: Mutator<ResultTable<ResultTableBackgroundType>>

      Mutator function for ResultTable

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>

setVisible

  • Set element visibility.

    Returns

    Object itself.

    Parameters

    • state: boolean

      true when element should be visible and false when element should be hidden.

    Returns AbstractCursor<CursorPositionType, ResultTableBackgroundType>
