  public ChartMarker()

Property Getters/Setters Detail

• 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
  public void chartDataPoint() throws Exception {
      Document doc = new Document();
      DocumentBuilder builder = new DocumentBuilder(doc);

      Chart chart = shape.getChart();
  
      Assert.assertEquals(3, chart.getSeries().getCount());
      Assert.assertEquals("Series 1", chart.getSeries().get(0).getName());

      // Smooth out the line that represents the first data series.
      chart.getSeries().get(0).setSmooth(true);

      }

      chart.getSeries().get(1).getDataPoints().removeAt(2);
  
      // We can also strip an entire series of data points at once.
      chart.getSeries().get(2).getDataPoints().clear();

• getSymbol/setSymbol

  public int getSymbol() / public void setSymbol(int value)
