  com.approximatrix.charting.render.AbstractChartRenderer
      com.approximatrix.charting.render.ScatterChartRenderer

All Implemented Interfaces:

Renderer

public class ScatterChartRenderer
extends AbstractChartRenderer

This renderer creates a scatter chart based on data contained in a ScatterDataModel. The renderer will draw line and/or markers, depending on the settings contained within each data set on the ScatterDataModel.

ScatterChartRenderer

public ScatterChartRenderer(CoordSystem cs,
                            ChartDataModel model)

Creates new LineChartRenderer

Parameters:

rcm - the RowColorModel needed to determine the right colors

cs - the ClassicCoordSystem used to translate values into points

model - the DataModel that should be rendered

Method Detail

renderChart

public void renderChart(java.awt.Graphics2D g)

Finally renders the Object in the Graphics object.

Specified by:

renderChart in class AbstractChartRenderer

Parameters:

g - the Graphics2D object in which to render

drawline

private void drawline(ScatterDataModel m,
