Properties

Protected activePointerEvents

activePointerEvents: Map<number, ModifierMouseArgs> = new Map()

Stores info about active pointerdown events

Protected changedPropertiesList

changedPropertiesList: string[] = []

enableHover

enableHover: boolean

When true, hover is enabled. Any series under 0the mouse or pointer on mouseMove will be notified as mouseOver

remarks

Enabling hover will decrease performance as a hit-test operation must be performed every mouse-move.

default

false

enableSelection

enableSelection: boolean

When true, Selection is enabled. Any series under the mouse or pointer device on mouseDown can be selected.

default

true

Protected executeOnProperty

executeOnProperty: EExecuteOn = EExecuteOn.MouseLeftButton

Readonly hoverChanged

hoverChanged: EventHandler<HoveredChangedArgs> = new EventHandler<HoveredChangedArgs>()

A hover-changed EventHandler. See EventHandler for how to subscribe to and be notified when any Series is hovered or unhovered

hoveredSeries

hoveredSeries: IRenderableSeries[] = []

An array of currently hovered series which can be observed by subscribing to the hoverChanged event handler

remarks

See documentation for how to subscribe to changes

Readonly id

id: string

A unique Id for the IChartModifierBase

invalidateParentCallback

invalidateParentCallback: () => void

A callback to invalidate the parent SciChartSurfaceBase

Type declaration

    • (): void
    • Returns void

Protected isAttachedProperty

isAttachedProperty: boolean

Protected isEnabledProperty

isEnabledProperty: boolean = true

modifierGroup

modifierGroup: string | undefined

Specifies a string ID to group modifiers.

remarks

When one receives a mouse event, all modifiers in the same group receive the event.

Protected mousePoint

mousePoint: Point | undefined

Protected parentSurfaceProperty

parentSurfaceProperty: SciChartSurface

Protected previousPoint

previousPoint: Point | undefined

Protected receiveHandledEventsProperty

receiveHandledEventsProperty: boolean

selectedSeries

selectedSeries: IRenderableSeries[] = []

An array of currently selected series which can be observed by subscribing to the selectionChanged event handler

remarks

See documentation for how to subscribe to changes

Readonly selectionChanged

selectionChanged: EventHandler<SelectionChangedArgs> = new EventHandler<SelectionChangedArgs>()

A selection-changed EventHandler. See EventHandler for how to subscribe to and be notified when any Series is selected or unselected

Readonly type

type: SeriesSelection = EChart2DModifierType.SeriesSelection

Protected typeMap

typeMap: Map<string, string> = new Map<string, string>()

Protected xAxisIdProperty

xAxisIdProperty: string = AxisCore.DEFAULT_AXIS_ID

xyDirection

xyDirection: EXyDirection = EXyDirection.XyDirection

Protected yAxisIdProperty

yAxisIdProperty: string = AxisCore.DEFAULT_AXIS_ID

  • When true, this modifier should receive events which have been handled by modifiers higher up in the call hierachy.

    inheritdoc

    Parameters

    • receiveHandledEvents: boolean

    Returns void

xAxisId

  • get xAxisId(): string

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.

    All elements within SciChart's High Performance Realtime JavaScript Charts which implement IDeletable must be deleted manually to free native (WebAssembly) memory

    Returns void

getAllSeries

Protected getIsActionAllowed

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
