getFont()

public Font getFont()

Provides access to the default font formatting of legend entries. To override the font formatting for a specific legend entry, use the ChartLegendEntry.getFont() property.

Examples:

Shows how to work with a legend font.


 Document doc = new Document(getMyDir() + "Reporting engine template - Chart series (Java).docx");
 Chart chart = ((Shape)doc.getChild(NodeType.SHAPE, 0, true)).getChart();

 ChartLegend chartLegend = chart.getLegend();
 // Set default font size all legend entries.
 chartLegend.getFont().setSize(14.0);
 // Change font for specific legend entry.
 chartLegend.getLegendEntries().get(1).getFont().setItalic(true);
 chartLegend.getLegendEntries().get(1).getFont().setSize(12.0);

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

Returns: Font - The corresponding Font value.

getFormat()

public ChartFormat getFormat()

Provides access to fill and line formatting of the legend.

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

 String[] categories = new String[] { "Category 1", "Category 2" };
 series.add("Series 1", categories, new double[] { 1.0, 2.0 });
 series.add("Series 2", categories, new double[] { 3.0, 4.0 });

 // Format chart background.
 chart.getFormat().getFill().solid(Color.darkGray);

 // Hide axis tick labels.
 chart.getAxisX().getTickLabels().setPosition(AxisTickLabelPosition.NONE);
 chart.getAxisY().getTickLabels().setPosition(AxisTickLabelPosition.NONE);

 // Format chart title.
 chart.getTitle().getFormat().getFill().solid(Color.yellow);

 // Format axis title.
 chart.getAxisX().getTitle().setShow(true);
 chart.getAxisX().getTitle().getFormat().getFill().solid(Color.yellow);
