You should therefore write to the Apache OpenOffice users mailing list,
instead of writing to LibreOffice documentation team.

Problems such as yours are usually generated by a difference in the
installed fonts, while charts are not embedded in the original document
but just linked (so, they are not part of the document).

Best regards.
