Utility class for displaying data points.
Library: ilvcharts
This class is a subclass of IlvChartDisplayerPoints that allows you to filter the points to display.
IlvChartDisplayerPoints. | IlvChartPointsFilter::IlvChartPointsFilter | ( | const IlvChartGraphic * | chart, |
| const IlvSingleChartDisplayer * | displayer, | ||
| IlvDim | clusterSize = 2 |
||
| ) |
Constructor.
Initializes a new IlvChartPointsFilter instance.
| chart | The associated chart. |
| displayer | The associated displayer. |
| clusterSize | The minimum distance between two consecutive displayed points. |
| IlvDim IlvChartPointsFilter::getClusterSize | ( | ) | const |
Returns the minimum distance between two consecutive displayed points.
|
virtual |
Initializes the current object with a set of data points to project.
This method performs the projection of the data points dataPoints and stores in the current object the resulting points and their corresponding data point indexes given by dataPtIdxes.
| count | The number of data points. |
| dataPoints | The data points to project. |
| dataPtIdxes | The indexes of the data points in the data set. |
| abscissaRange | The range of the abscissa coordinate that is currently used by the chart. |
| shiftOfCycleLength | A Boolean value indicating whether the data points are shifted by the cycle length. |
| t | The transformer applied to the chart graphic. |
Reimplemented from IlvChartDisplayerPoints.
| void IlvChartPointsFilter::setClusterSize | ( | IlvDim | size | ) |
Sets the minimum distance between two consecutive displayed points.
| size | The new minimum distance between two consecutive displayed points. |
