public boolean getBubble3D() / public void setBubble3D(boolean value)

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

public int getExplosion() / public void setExplosion(int value)

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.

public ChartFormat getFormat()

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

Example:

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");

public int getIndex()

Index of the data point this object applies formatting to.

Example:

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

public boolean getInvertIfNegative() / public void setInvertIfNegative(boolean value)

Specifies whether the parent element shall inverts its colors if the value is negative.

public ChartMarker getMarker()

Specifies chart data marker.

public void clearFormat()

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