Constructor Detail

### XSLFChart

    protected XSLFChart(PackagePart part)
                 throws java.io.IOException,
                        org.apache.xmlbeans.XmlException

  Construct a chart from a package part.

  Parameters:
    `part` - the package part holding the chart data, the content type must be `application/vnd.openxmlformats-officedocument.drawingml.chart+xml`
  Throws:
    `java.io.IOException`
    `org.apache.xmlbeans.XmlException`
  Since:
    POI 3.14-Beta1

Method Detail

### getCTChartSpace

    @Internal
    public org.openxmlformats.schemas.drawingml.x2006.chart.CTChartSpace getCTChartSpace()

  Return the underlying CTChartSpace bean, the root element of the Chart part.

  Returns:
    the underlying CTChartSpace bean

### getCTChart

    @Internal
    public org.openxmlformats.schemas.drawingml.x2006.chart.CTChart getCTChart()

  Return the underlying CTChart bean, within the Chart Space

  Returns:
    the underlying CTChart bean

### commit

    protected void commit()
                   throws java.io.IOException

  Description copied from class: `POIXMLDocumentPart`
  Save the content in the underlying package part. Default implementation is empty meaning that the package part is left unmodified. Sub-classes should override and add logic to marshal the "model" into Ooxml4J. For example, the code saving a generic XML entry may look as follows:

       protected void commit() throws IOException {
         PackagePart part = getPackagePart();
         OutputStream out = part.getOutputStream();
         XmlObject bean = getXmlBean(); //the "model" which holds changes in memory
         bean.save(out, DEFAULT_XML_OPTIONS);
         out.close();
       }

  Overrides:
    `commit` in class `POIXMLDocumentPart`
  Throws:
    `java.io.IOException` - a subclass may throw an IOException if the changes can't be committed
