The type of the elements returned by the
::com::sun::star::container::XIndexAccess must
be a component that supports the service
::com::sun::star::chart2::DataSequence , thus implements
::com::sun::star::chart2::XDataSequence .
If the data stored consists only of floating point numbers (double
values), the returned instances should also support the service
::NumericalDataSequence .
If the data stored consists only of strings, the returned
instances should also support the service
::TextualDataSequence .
