Constructor Detail

XSSFChart

protected XSSFChart()
Create a new SpreadsheetML chart

XSSFChart

protected XSSFChart(PackagePart part,
                    PackageRelationship rel)
             throws java.io.IOException,
                    org.apache.xmlbeans.XmlException
Construct a SpreadsheetML 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
rel - the package relationship holding this chart, the relationship type must be http://schemas.openxmlformats.org/officeDocument/2006/relationships/chart
Throws:
java.io.IOException
org.apache.xmlbeans.XmlException
Method Detail

getCTChartSpace

@Internal
public org.openxmlformats.schemas.drawingml.x2006.chart.CTChartSpace getCTChartSpace()
Return the underlying CTChartSpace bean, the root element of the SpreadsheetML 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

the graphic frame this chart belongs to
