The problem only occurs if you have GDI+ mode activate. In Delphi occurs, too. Delphi Code: uses Series, TeExport; procedure TForm1.FormCreate(Sender: TObject); begin Chart1.AddSeries(TLineSeries).FillSampleValues; end; procedure TForm1.Button1Click(Sender: TObject); begin TeeExport(Self, Chart1); end; Fixed. After creating the Metafile (using a TMetafileCanvas), the problem was the "real" GDI+ chart canvas still had a wrong reference to the metafile canvas at its private "IXorCanvas" variable (used to draw the zoom rectangle when clicking and dragging a chart) |
