Take a look at procedure TGDIPlusCanvas.RecreateGraphics(const AHandle:HDC);

In case something went wrong creating the GD+ canvas, it checks FGraphics.LastStatus and raises an exception of class Exception in case something went wrong.
Please change this into a more informational exception specialized for TChart, OR (as I did) call raiseLastOSError rather than Raise Exception.Create(IntToStr(Ord(Status)));
