ChartDataPoint

Inheritance: java.lang.Object

All Implemented Interfaces: com.aspose.words.IChartDataPoint, java.lang.Cloneable

public class ChartDataPoint implements IChartDataPoint, Cloneable

Allows to specify formatting of a single data point on the chart.

To learn more, visit the Working with Charts documentation article.

Remarks:

On a series, the ChartDataPoint object is a member of the ChartDataPointCollection. The ChartDataPointCollection contains a ChartDataPoint object for each point.

Examples:

Shows how to work with data points on a line chart.

clearFormat()

public void clearFormat()

Clears format of this data point. The properties are set to the default values defined in the parent series.

getBubble3D()

public boolean getBubble3D()

Specifies whether the bubbles in Bubble chart should have a 3-D effect applied to them.

Returns: boolean - The corresponding boolean value.

getExplosion()

public int getExplosion()

Specifies the amount the data point shall be moved from the center of the pie. Can be negative, negative means that property is not set and no explosion should be applied. Applies only to Pie charts.

Returns: int - The corresponding int value.

getFormat()

public ChartFormat getFormat()

Provides access to fill and line formatting of this data point.

Examples:

Shows how to set individual formatting for categories of a column chart.


 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 Shape shape = builder.insertChart(ChartType.COLUMN, 432.0, 252.0);
 Chart chart = shape.getChart();

 // Delete default generated series.
 chart.getSeries().clear();

 // Adding new series.
 ChartSeries series = chart.getSeries().add("Series 1",
         new String[] { "Category 1", "Category 2", "Category 3", "Category 4" },
         new double[] { 1.0, 2.0, 3.0, 4.0 });

 // Set column formatting.
 ChartDataPointCollection dataPoints = series.getDataPoints();
 dataPoints.get(0).getFormat().getFill().presetTextured(PresetTexture.DENIM);
 dataPoints.get(1).getFormat().getFill().setForeColor(Color.RED);
 dataPoints.get(2).getFormat().getFill().setForeColor(Color.YELLOW);
 dataPoints.get(3).getFormat().getFill().setForeColor(Color.BLUE);

 doc.save(getArtifactsDir() + "Charts.DataPointsFormatting.docx");

Returns: ChartFormat - The corresponding ChartFormat value.

getIndex()

public int getIndex()

Index of the data point this object applies formatting to.

Examples:

Shows how to work with data points on a line chart.
