public class ChartSeriesGroup
```

Represents properties of a chart series group, that is, the properties of chart series of the same type associated with the same axes.

 **Remarks:** 

Combo charts contains multiple chart series groups, with a separate group for each series type.

Also, you can create a chart series group to assign secondary axes to one or more chart series.

To learn more, visit the [ Working with Charts ][Working with Charts] documentation article.

 **Examples:** 

Shows how to work with the secondary axis of chart.

```

 Document doc = new Document();

 Shape shape = builder.insertChart(ChartType.LINE, 450.0, 250.0);

 seriesGroup.setOverlap(-75);

 doc.save(getArtifactsDir() + "Charts.ConfigureGapOverlap.docx");
 
```

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | int | The percentage of gap width between chart elements. |

### setOverlap(int value) {#setOverlap-int}
```
public void setOverlap(int value)
```


Sets the percentage of how much the series bars or columns overlap.

 **Remarks:** 

Applies to series groups of all bar and column types.

The range of acceptable values is from -100 to 100 inclusive. A value of 0 indicates that there is no space between bars/columns. If the value is -100, the distance between bars/columns is equal to their width. A value of 100 means that the bars/columns overlap completely.

 **Examples:** 

Show how to configure gap width and overlap.

```

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

 Shape shape = builder.insertChart(ChartType.COLUMN, 450.0, 250.0);
 ChartSeriesGroup seriesGroup = shape.getChart().getSeriesGroups().get(0);

 // Set column gap width and overlap.
 seriesGroup.setGapWidth(450);
 seriesGroup.setOverlap(-75);

 doc.save(getArtifactsDir() + "Charts.ConfigureGapOverlap.docx");
 
```

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | int | The percentage of how much the series bars or columns overlap. |

### setSecondSectionSize(int value) {#setSecondSectionSize-int}
```
public void setSecondSectionSize(int value)
```


Sets the size of the pie chart secondary section as a percentage.

 **Remarks:** 

Applies to series groups of the [ChartSeriesType.PIE\_OF\_PIE](../../com.aspose.words/chartseriestype/\#PIE-OF-PIE) and [ChartSeriesType.PIE\_OF\_BAR](../../com.aspose.words/chartseriestype/\#PIE-OF-BAR) types.

The range of acceptable values is from 5 to 200 inclusive. The default value is 75.

 **Examples:** 

Shows how to create and format pie of Pie chart.

```

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

 Shape shape = builder.insertChart(ChartType.PIE_OF_PIE, 440.0, 300.0);
 Chart chart = shape.getChart();
 // Delete the default generated series.
 chart.getSeries().clear();

 String[] categories = new String[] { "Category 1", "Category 2", "Category 3", "Category 4" };
 chart.getSeries().add("Series 1", categories, new double[] { 11.0, 8.0, 4.0, 3.0 });

 // Format the Pie of Pie chart.
 ChartSeriesGroup seriesGroup = chart.getSeriesGroups().get(0);
 seriesGroup.setGapWidth(10);
 seriesGroup.setSecondSectionSize(77);

 doc.save(getArtifactsDir() + "Charts.PieOfPieChart.docx");
 
```

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | int | The size of the pie chart secondary section as a percentage. |
