The RubberBandXyZoomModifier provides drag-rectangle to zoom behavior on a 2D SciChartSurface within SciChart - High Performance JavaScript Charts

remarks

To apply the RubberBandXyZoomModifier to a SciChartSurface and add drag to zoom behavior, use the following code:

const sciChartSurface: SciChartSurface;
sciChartSurface.chartModifiers.add(new RubberBandXyZoomModifier());

Animation of the zoom may be controlled via the RubberBandXyZoomModifier.isAnimated, RubberBandXyZoomModifier.animationDuration and RubberBandXyZoomModifier.easingFunction properties.

Properties

animationDuration

animationDuration: number = 400

Defines the duration of animations when zooming in milliseconds

Protected changedPropertiesList

changedPropertiesList: string[] = []

Defines the easing function for animation. See TEasingFn for a range of functions

Readonly id

id: string

A unique Id for the IChartModifierBase

invalidateParentCallback: () => void

A callback to invalidate the parent SciChartSurfaceBase

Type declaration

    • (): void
    • Returns void

isAnimated

isAnimated: boolean = true

When true, the Zoom operations are animated. See also animationDuration and easingFunction

Protected isAttachedProperty

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

Protected getAllSeries

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

modifierDoubleClick

modifierMouseDown

modifierMouseEnter

modifierMouseLeave

modifierMouseMove

modifierMouseUp

modifierMouseWheel
