- # This is an example of an OpenDocument Chart.
- #
- # Opendocument charts are usually not found in the wild. They are intended to be
- # subobojects of e.g. spreadsheets. But the KDE application called kchart
- # (http://www.koffice.org/kchart/) is able to read and write ODC files.
- #
- # Kchart is able to understand a document without <chart:series>, whereas
- # OOo misinterprets the label rows and columns. So if you embed the
- # spectre-balance.odc file in an OOo Writer document, expect to see some
- # oddities.
