With this class you can import a <chart:chart> element containing its data as <table:table> element o...
SvXMLImportContext * CreateChartContext(SvXMLImport &rImport, const css::uno::Reference< css::frame::XModel > &rChartModel)
get the context for reading the <chart:chart> element with subelements.
This class deliberately does not support XWeak, to improve performance when loading large documents.
