|
* @brief The IDataSeries aims to declare a data series.
|
|
|
*
|
|
|
* A data series is an entity that contains at least :
|
|
|
* - one dataset representing the x-axis
|
|
|
* - one dataset representing the values
|
|
|
*
|
|
|
* Each dataset is represented by an ArrayData, and is associated with a unit.
|
|
|
*
|
|
|
* An ArrayData can be unidimensional or two-dimensional, depending on the implementation of the
|
|
|
* IDataSeries. The x-axis dataset is always unidimensional.
