HistogramChart

All Implemented Interfaces:

Portlet, Portlet

public class HistogramChart
extends AbstractChartBuilder<HistogramChart>

Builder for a Histogram, obtained via ChartBuilder.newHistogram() rather than instantiated directly. See that factory method for this chart's single-series shape (one series, obtained with getSeries() rather than addSeries()) and a Groovy example.

Methods of this class are mostly self-explanatory or equivalent to the Highcharts methods described at HighCharts.Chart.

Method Details

getSeries

public HistogramChart.HistogramSeries getSeries()

Returns this chart's single series. Unlike other chart types, a Histogram has exactly one series; this method always returns the same instance rather than adding a new one on each call.

Returns:

this chart's HistogramChart.HistogramSeries. Never null.

getOptions

public HistogramChart.HistogramOptions getOptions()

Description copied from class: AbstractChartBuilder

Returns this chart's Options builder. Each concrete chart type declares its own Options subclass (for example ScatterChart.ScatterOptions, BarLineChart.BarLineOptions) exposing the settings that apply to that chart type, such as title, subtitle, and axis label and bound overrides; the exact set of available options differs per chart type, which is why this method is declared abstract here rather than implemented once for every chart.

Specified by:

getOptions in class AbstractChartBuilder<HistogramChart>

Returns:

this chart's type-specific AbstractChartOptions instance. Never null.

addAuxLine

public AuxLine<HistogramChart> addAuxLine()

Adds a horizontal, vertical, or stepped reference line to this chart, independent of its data series, for example a fixed target or threshold value. Call AuxLine.withLine(), AuxLine.withSteppedLine(), or AuxLine.withVerticalLine() on the returned builder to choose the line's shape.

Overrides:

addAuxLine in class AbstractChartBuilder<HistogramChart>

Returns:

a new AuxLine builder for this chart. Never null.

build

public ChartBuilderResult build()

Finishes this chart's definition. The returned object is what Dashboard portlets, Quote headers, and other Data Analyzer areas render.

Specified by:

build in class AbstractBuilder

Returns:

the finished chart definition. Never null.
