Data Classes
The base class used to represent a chart data object is the
IlvAbstractChartData class. A subclass called
IlvMemoryChartData that stores the data sets it manages in memory is provided in the library.
The data sets managed by a chart data object are all instances of subclasses of the
IlvChartDataSet class. Several subclasses of the
IlvChartDataSet class are provided to allow you to define a set of data to be displayed by a chart in different ways. A data set can be defined as:
A set of points with two coordinates
This kind of data set is represented by an instance of the
IlvChartPointSet class. The data points managed by this data set are instances of the
IlvDoublePoint class that allows you to represent a point with two coordinates of the
IlvDouble type.
A set of values
This kind of data set is represented by an instance of the
IlvChartYValueSet class. The data values managed by this data set are of the
IlvDouble type. These values correspond to the ordinates of the data points that will be displayed. The abscissa of the data points are by definition the indexes of the stored values.
