Property Getters/Setters Detail

• getFormat

  public ChartFormat getFormat()
  

  Provides access to fill and line formatting of this marker.

  Example:

  Show how to set marker formatting.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  Shape shape = builder.insertChart(ChartType.SCATTER, 432.0, 252.0);
  Chart chart = shape.getChart();
  
  // Delete default generated series.
  chart.getSeries().clear();
  ChartSeries series = chart.getSeries().add("AW Series 1", new double[] { 0.7, 1.8, 2.6, 3.9 },
          new double[] { 2.7, 3.2, 0.8, 1.7 });
  
  // Set marker formatting.
  series.getMarker().setSize(40);
  series.getMarker().setSymbol(MarkerSymbol.SQUARE);
  ChartDataPointCollection dataPoints = series.getDataPoints();
  dataPoints.get(0).getMarker().getFormat().getFill().presetTextured(PresetTexture.DENIM);
  dataPoints.get(0).getMarker().getFormat().getStroke().setForeColor(Color.YELLOW);
  dataPoints.get(0).getMarker().getFormat().getStroke().setBackColor(Color.RED);
  dataPoints.get(1).getMarker().getFormat().getFill().presetTextured(PresetTexture.WATER_DROPLETS);
  dataPoints.get(1).getMarker().getFormat().getStroke().setForeColor(Color.YELLOW);
  dataPoints.get(1).getMarker().getFormat().getStroke().setVisible(false);
  dataPoints.get(2).getMarker().getFormat().getFill().presetTextured(PresetTexture.GREEN_MARBLE);
  dataPoints.get(2).getMarker().getFormat().getStroke().setForeColor(Color.YELLOW);
  dataPoints.get(3).getMarker().getFormat().getFill().presetTextured(PresetTexture.OAK);
  dataPoints.get(3).getMarker().getFormat().getStroke().setForeColor(Color.YELLOW);
  dataPoints.get(3).getMarker().getFormat().getStroke().setTransparency(0.5);
  
  doc.save(getArtifactsDir() + "Charts.MarkerFormatting.docx");

• getSize/setSize

  public int getSize() / public void setSize(int value)
  

  Gets or sets chart marker size. Default value is 7.

  Example:

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

  @Test

      for (ChartSeries series : chart.getSeries())
          applyDataPoints(series, 4, MarkerSymbol.DIAMOND, 15);
  
      // Smooth out the line that represents the first data series.
