// Create a sample series...
PointSeries:=TPointSeries.Create(Self);
Chart1.AddSeries(PointSeries);
// Create an XML source...
XML:=TTeeXMLSource.Create(Self);
// Configure XML...
XML.XML.Text:=Memo2.Text; // <--- set text string with XML data
// XML.FileName:='c:\mydata.xml'; <--- or load xml file
XML.Series:=PointSeries; // <-- series to fill
XML.SeriesNode:='Series1'; // <-- xml node to use
XML.ValueSource:='Y'; // <-- xml "point" attribute to use as value
// Load data, fill series...
XML.Open;
