Property Getters/Setters Detail

• getCount

  public int getCount()
  

  Returns the number of ChartSeries in this collection.

  Example:

  Shows how to add and remove series data in a chart.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert a column chart that will contain three series of demo data by default.
  Shape chartShape = builder.insertChart(ChartType.COLUMN, 400.0, 300.0);
  Chart chart = chartShape.getChart();
  
  // Each series has four decimal values; one for each of the four categories.
  // Four clusters of three columns will represent this data.
  ChartSeriesCollection chartData = chart.getSeries();
  
  Assert.assertEquals(3, chartData.getCount());
  
  // Print the name of every series in the chart.
  Iterator<ChartSeries> enumerator = chart.getSeries().iterator();
  while (enumerator.hasNext()) {
      System.out.println(enumerator.next().getName());
  }
  
  // These are the names of the categories in the chart.
  String[] categories = { "Category 1", "Category 2", "Category 3", "Category 4" };
  
  // We can add a series with new values for existing categories.
  // This chart will now contain four clusters of four columns.
  chart.getSeries().add("Series 4", categories, new double[] { 4.4, 7.0, 3.5, 2.1 });
  
  // A chart series can also be removed by index, like this.
  // This will remove one of the three demo series that came with the chart.
  chartData.removeAt(2);
  
  Assert.assertFalse(IterableUtils.matchesAny(chartData, s -> s.getName() == "Series 3"));
  
  // We can also clear all of the chart's data at once with this method.
  // When creating a new chart, this is the way to wipe all the demo data
  // before we can begin working on a blank chart.
  chartData.clear();

• get

  public ChartSeries get(int index)
  

  Returns a ChartSeries at the specified index.

  The index is zero-based.

  Negative indexes are allowed and indicate access from the back of the collection. For example -1 means the last item, -2 means the second before last and so on.

  If index is greater than or equal to the number of items in the list, this returns a null reference.

  If index is negative and its absolute value is greater than the number of items in the list, this returns a null reference.

  Parameters:

  index - An index into the collection.

• clear

  public void clear()

  Removes all ChartSeries from this collection.

  Example:

  Shows how to add and remove series data in a chart.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert a column chart that will contain three series of demo data by default.
  Shape chartShape = builder.insertChart(ChartType.COLUMN, 400.0, 300.0);
  Chart chart = chartShape.getChart();
  
  // Each series has four decimal values; one for each of the four categories.
  // Four clusters of three columns will represent this data.
  ChartSeriesCollection chartData = chart.getSeries();
  
  Assert.assertEquals(3, chartData.getCount());
  
  // Print the name of every series in the chart.
  Iterator<ChartSeries> enumerator = chart.getSeries().iterator();
  while (enumerator.hasNext()) {
      System.out.println(enumerator.next().getName());
  }
  
  // These are the names of the categories in the chart.
  String[] categories = { "Category 1", "Category 2", "Category 3", "Category 4" };
  
  // We can add a series with new values for existing categories.
  // This chart will now contain four clusters of four columns.
  chart.getSeries().add("Series 4", categories, new double[] { 4.4, 7.0, 3.5, 2.1 });
  
  // A chart series can also be removed by index, like this.
  // This will remove one of the three demo series that came with the chart.
  chartData.removeAt(2);
  
  Assert.assertFalse(IterableUtils.matchesAny(chartData, s -> s.getName() == "Series 3"));
  
  // We can also clear all of the chart's data at once with this method.
  // When creating a new chart, this is the way to wipe all the demo data
  // before we can begin working on a blank chart.
  chartData.clear();

• iterator

  public java.util.Iterator<ChartSeries> iterator()

  Returns an enumerator object.

• removeAt

  public void removeAt(int index)

  Removes a ChartSeries at the specified index.

  Parameters:

  index - The zero-based index of the ChartSeries to remove.

  Example:
