public class ChartSeriesGroupCollection implements Iterable
```

Represents a collection of [ChartSeriesGroup](../../com.aspose.words/chartseriesgroup/) objects.

 **Remarks:**

 **Examples:** 

Shows how to work with the secondary axis of chart.

```

 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 Shape shape = builder.insertChart(ChartType.LINE, 450.0, 250.0);
 Chart chart = shape.getChart();
 ChartSeriesCollection series = chart.getSeries();

 // Delete default generated series.
 series.clear();

 String[] categories = new String[] { "Category 1", "Category 2", "Category 3" };
 series.add("Series 1 of primary series group", categories, new double[] { 2.0, 3.0, 4.0 });
 series.add("Series 2 of primary series group", categories, new double[] { 5.0, 2.0, 3.0 });

 // Create an additional series group, also of the line type.
 ChartSeriesGroup newSeriesGroup = chart.getSeriesGroups().add(ChartSeriesType.LINE);
 // Specify the use of secondary axes for the new series group.
 newSeriesGroup.setAxisGroup(AxisGroup.SECONDARY);
 // Hide the secondary X axis.
 newSeriesGroup.getAxisX().setHidden(true);
 // Define title of the secondary Y axis.
 newSeriesGroup.getAxisY().getTitle().setShow(true);
 newSeriesGroup.getAxisY().getTitle().setText("Secondary Y axis");

 Assert.assertEquals(ChartSeriesType.LINE, newSeriesGroup.getSeriesType());

 // Add a series to the new series group.
 ChartSeries series3 =
         newSeriesGroup.getSeries().add("Series of secondary series group", categories, new double[] { 13.0, 11.0, 16.0 });
 series3.getFormat().getStroke().setWeight(3.5);
