13 * @brief The OptionalAxis class defines an optional data axis for a series of data.
14 *
15 * An optional data axis is an axis that can be defined or not for a data series. If defined, it
16 * contains a unit and data (1-dim ArrayData). It is then possible to access the data or the unit.
17 * In the case of an undefined axis, the axis has no data and no unit. The methods for accessing the
18 * data or the unit are always callable but will return undefined values.
19 *
