public class RadarPlotter

extends Plotter

Class used to plot radar charts. The following example shows how to create a radar chart:
// data to plot
double[] d1={1,2,3,4,5};
double[] d2={2,3,4,4.2,3};
// create data series
LineDataSerie data1= new LineDataSerie(d1,new LineStyle(2f,GraphicsProvider.getColor(ChartColor.BLUE),LineStyle.LINE_NORMAL));
data1.drawPoint=true;
data1.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10);
LineDataSerie data2= new LineDataSerie(d2,new LineStyle(2f,GraphicsProvider.getColor(ChartColor.GREEN),LineStyle.LINE_NORMAL));
data2.drawPoint=true;
data2.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10);
data2.fillStyle=new FillStyle(GraphicsProvider.getColor(ChartColor.GREEN));
// create legend
Legend l=new Legend();
l.background=new FillStyle(GraphicsProvider.getColor(ChartColor.WHITE));
l.border=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL);
l.addItem("Products",new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLUE),LineStyle.LINE_NORMAL));
l.addItem("Services",new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.GREEN),LineStyle.LINE_NORMAL));
// create title
Title title=new Title("Sales (thousands $)");
// create plotter
RadarPlotter plot=new RadarPlotter();
double[] fMaxs={6,6,6,6,6};
double[] fMins={0,0,0,0,0};
String[] factors={"Factor1","Factor2","Factor3","Factor4","Factor5","Factor6"};
plot.factorMaxs=fMaxs;
plot.factorMins=fMins;
plot.factorNames=factors;
plot.backStyle=new FillStyle(GraphicsProvider.getColor(ChartColor.YELLOW));
plot.gridStyle=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_DASHED);
plot.gridFont=GraphicsProvider.getFont("Arial",ChartFont.PLAIN,10);
// create chart using radar plotter
Chart chart=new Chart(title,plot,null,null);
chart.back=new FillStyle(GraphicsProvider.getColor(ChartColor.RED));
chart.back.gradientType=FillStyle.GRADIENT_HORIZONTAL;
chart.legend=l;
// add data series to the chart
chart.addSerie(data2);
chart.addSerie(data1);
