Class defining a data set representing the percentage of a data set relative to the sum of the data sets.
Library: ilvcharts
This class is a subclass of IlvCombinedChartDataSet that allows you to define a stacked-100-data-set. This type of data set is computed for a given real data set that is part of a set of real data sets. The values of the stacked-100-data-set correspond to the percentage represented by each data value of the given data set relative to the total across the set of real data sets.
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 a stacked-100-data-set. The real data sets that make up the stacked-100-data-set are shown in the left column and the stacked-100-data-set that is constructed from these data sets is shown in the right column. The percentages are computed for the first real data set, but they can be computed for each real data set that makes up the stacked-100-data-set.
| Data-set-1 | Stacked-100-data-set |
| (0, 0.7) | (0, 35) |
| (1, 0.6) | (1, 40) |
| (2, 0.9) | (2, 37.5) |
| Data-set-2 | - |
| (0, 1.3) | - |
| (1, 0.9) | - |
| (2, 1.5) | - |

Retrieves from a data point of the current combined data set the corresponding data point of a component data set.
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. |
