Wijmo_Angular2_Chart_Analytics.Wjflexchartwaterfall

WjFlexChartWaterfall Class

Angular 2 component for the wijmo.chart.analytics.Waterfall class.

The wj-flex-chart-waterfall component must be contained in one of the following components: wijmo.angular2.chart.WjFlexChart or wijmo.angular2.chart.finance.WjFinancialChart.

Use the wj-flex-chart-waterfall component to add Waterfall controls to your Angular 2 applications. For details about Angular 2 markup syntax, see Angular 2 Markup.

The WjFlexChartWaterfall component is derived from the Waterfall class and inherits all its properties, events and methods.

Gets or sets a value that determines whether to show intermediate total bars.

This property works with intermediateTotalPositions and intermediateTotalLabels properties.

showTotal

showTotal: boolean

Gets or sets a value that determines whether to show the total bar at the end of the chart.

Methods

created

  • created(): void

  • If you create a custom component inherited from a Wijmo component, you can override this method and perform necessary initializations that you usually do in a class constructor. This method is called in the last line of a Wijmo component constructor and allows you to not declare your custom component's constructor at all, thus preventing you from a necessity to maintain constructor parameters and keep them in synch with Wijmo component's constructor parameters.

    Returns void

dataToPoint

getDataRect

  • getDataRect(currentRect?: Rect, calculatedRect?: Rect): Rect

  • Returns the series bounding rectangle in data coordinates.

    If getDataRect() returns null, the limits are calculated automatically based on the data values.

    Parameters

    • Optional currentRect: Rect

      The current rectangle of chart. This parameter is optional.

    • Optional calculatedRect: Rect

      The calculated rectangle of chart. This parameter is optional.

    Returns Rect

getPlotElement

  • getPlotElement(pointIndex: number): any

  • Gets the plot element that corresponds to the specified point index.

    Parameters

    • pointIndex: number

      The index of the data point.

    Returns any

hitTest

  • Gets a HitTestInfo object with information about the specified point.

    Parameters

    • pt: any

      The point to investigate, in window coordinates.

    • Optional y: number

      The Y coordinate of the point (if the first parameter is a number).

    Returns HitTestInfo

initialize

  • initialize(options: any): void

  • Initializes the series by copying the properties from a given object.

    Parameters

    • options: any

      JavaScript object containing initialization data for the series.

    Returns void

onRendered

onRendering

  • onRendering(engine: IRenderEngine, index: number, count: number): boolean

pointToData

  • Converts a Point from control coordinates to series data coordinates.

    Parameters

    • pt: Point

      The point to convert, in control coordinates.

    Returns Point

    The point in series data coordinates.

Events
