Constructor Detail

IlvDisplayPoint

public IlvDisplayPoint()

Creates a new IlvDisplayPoint object associated with no renderer with no data set.

IlvDisplayPoint

public IlvDisplayPoint(IlvChartRenderer renderer,
                       IlvDataSet dataSet)

Creates a new IlvDisplayPoint object associated with the specified renderer and data set representing a data at index 0 with (0,0) as coordinates.

IlvDisplayPoint

public IlvDisplayPoint(IlvChartRenderer renderer,
                       IlvDataSet dataSet,
                       int index,
                       double xCoord,
                       double yCoord)

Creates a new IlvDisplayPoint object.

Parameters:

renderer - The chart renderer associated with this display point.

dataSet - The data set holding the data it represents.

index - The index of the data in the data set.

xCoord - The projected x-coordinate of the data point.

yCoord - The projected y-coordinate of the data point.

Method Detail

set

public void set(int index,
                double xCoord,
                double yCoord)

Changes the values of this display point.

Parameters:

index - The index of the data in the data set.

xCoord - The projected x-coordinate of the data point.

yCoord - The projected y-coordinate of the data point.

getRenderer

public final IlvChartRenderer getRenderer()

Returns the chart renderer associated with this display point.

getXCoord

public final double getXCoord()

Returns the projected x-coordinate of this display point.

getYCoord

public final double getYCoord()

Returns the projected y-coordinate of this display point.

setCoords

public void setCoords(int xCoord,
                      int yCoord)

Changes the values of the referenced data point, using the specified projected coordinates.

IlvChartRenderer.setDisplayPoint(ilog.views.chart.data.IlvDataSet, int, double, double)

setData

public void setData(double xData,
                    double yData)

Changes the values of this display point, using the specified data values.

Overrides:

setData in class IlvDataSetPoint

See Also:

IlvChartRenderer.setDataPoint(ilog.views.chart.data.IlvDataSet, int, double, double)

isEditable

public boolean isEditable()

Indicates whether this point can be edited by modifying its display coordinates.

equals

public boolean equals(Object obj)

Returns whether this display point is equal to the specified display point. By definition, two display points are equal if they reference the same renderer and their projected coordinates are equals.

Overrides:

equals in class IlvDataSetPoint
