Class defining a combined data set as the addition of other data sets.
Library: ilvcharts
This class is a subclass of IlvCombinedChartDataSet which allows you to define a data set as the addition of any number of other data sets. The nth data point of the add-data-set will correspond to the sum of the nth data points of all the real data sets that make up this data set.
This type of data set is used by the stacked displayers to put the data to be displayed into a format that the displayer can display. See the IlvStackedChartDisplayer class to have more information.
The following example illustrates an add-data-set. The real data sets that make up the add-data-set are shown in the left column and the add-data-set that is constructed from these data sets is shown in the right column. The addition is performed only for the Y values as in the stacked displayers, but it can also be performed for the X values.
| Data-set-1 | Add-data-set |
| (0, 0.7) | (0, 2.0) |
| (1, 0.6) | (1, 1.5) |
| (2, 0.9) | (2, 2.4) |
| Data-set-2 | - |
| (0, 1.3) | - |
| (1, 0.9) | - |
| (2, 1.5) | - |
|

0), dataSet is set to a default data set which is one of the data sets that make up the current combined data set.| dataSet | The component data set for which we want to retrieve a data point. This data set is one of the data sets that make up the current combined data set. |
| ptidx | The index of the data point of the current combined data set from which we want to retrieve the corresponding point in dataSet. |
| point | The point of the current combined data set from which we want to retrieve the corresponding point in dataSet. |
| dataSetPointIndex | The index of the retrieved point in the data set dataSet. |
| dataSetPoint | The retrieved point in the data set dataSet. |
IlTrue if the data point has been successfully retrieved and IlFalse otherwise. Implements IlvCombinedChartDataSet.
