@param eLabelOrigin
denotes what part of the range should be used for label
generation. If you have, e.g., one cell only, the
parameter COLUMN enables you to get the name of the cell's
column, the parameter ROW will give you its row name.
If you have a non quadratic range you can ask for labels for
the longer side with parameter LONG_SIDE or you can obtain labels
for the shorter side with parameter SHORT_SIDE.
If the range is not structured in a tabular way you may receive
no label.
@return
Suitable labels for the given sequence depending on the range
of the sequence and the parameter <code>eLabelOrigin</code> passed.
In a spreadsheet this would typically be a label like "Column x"
for the short side used as DataSeries name and maybe a
sequence "Row 1" "Row 2" "Row 3" for the long side to be used
as categories for example.
Example: Assuming this sequence has a Range representation spanning
row 5 and 6 in column 8. Following sequences of strings or similar strings
are expected as return values:
generateLabel( SHORT_SIDE ) -> "Column 8"
generateLabel( LONG_SIDE ) -> "Row 5" "Row 6"
generateLabel( COLUMN ) -> "Column 8"
generateLabel( ROW ) -> "Row 5" "Row 6"
Which strings exactly you return depends on the naming scheme of the application
which provides its tabular data.
