Method Detail

drawLegendSymbol

public javafx.scene.canvas.Canvas drawLegendSymbol(de.gsi.dataset.DataSet dataSet,
                                                   int dsIndex,
                                                   int width,
                                                   int height)

Specified by:

drawLegendSymbol in interface Renderer

Parameters:

dataSet - the data set for which the representative icon should be generated

dsIndex - index within renderer set

width - requested width of the returning Canvas

height - requested height of the returning Canvas

Returns:

a graphical icon representation of the given data sets

getMaxPoints

public int getMaxPoints()

getThis

protected ReducingLineRenderer getThis()

Specified by:

getThis in class AbstractDataSetManagement<ReducingLineRenderer>

Returns:

the instance of this ReducingLineRenderer.

render

public java.util.List<de.gsi.dataset.DataSet> render(javafx.scene.canvas.GraphicsContext gc,
                                                     Chart chart,
                                                     int dataSetOffset,
                                                     javafx.collections.ObservableList<de.gsi.dataset.DataSet> datasets)

Specified by:

render in interface Renderer

Parameters:

gc - the Canvas' GraphicsContext the renderer should draw upon

chart - the corresponding chart

dataSetOffset - global offset of the last drawn DataSet

datasets - list of globally (ie. in Chart) stored DataSets

Returns:

List of drawn DataSets (N.B. return '0' in case Renderer.showInLegend() is false)

setMaxPoints

public void setMaxPoints(int maxPoints)
