public class RangeBarChart

  1. Object
  2. AbstractChart
  3. XYChart
  4. BarChart
  5. RangeBarChart

Known subtypesRangeStackedBarChart

Extends BarChart to support values that represent ranges rather than single points. Each bar is drawn from the lower value to the upper value in the dataset.

Use this chart with an XYMultipleSeriesDataset containing XYSeries instances where consecutive entries form the minimum/maximum pair for a category.

Fields

public static final String TYPE = "RangeBar"The chart type.

Constructors

public RangeBarChart(XYMultipleSeriesDataset dataset, XYMultipleSeriesRenderer renderer, BarChart.Type type)Builds a new range bar chart instance.

Methods

public void drawSeries(Canvas canvas, Paint paint, List<Float> points, XYSeriesRenderer seriesRenderer, float yAxisValue, int seriesIndex, int startIndex)The graphical representation of a series.
protected void drawChartValuesText(Canvas canvas, XYSeries series, XYSeriesRenderer renderer, Paint paint, List<Float> points, int seriesIndex, int startIndex)The graphical representation of the series values as text.
protected float getCoeficient()Returns the value of a constant used to calculate the half-distance.
public String getChartType()Returns the chart type identifier.
