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
com.java4less.rchart.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);

Field Detail

radiusModifier

public double radiusModifier

modifies the size of thechart. The default value is 1. A value of 0.5 will create a chart half the size of the default.

drawCircle

public boolean drawCircle

if true a circle will be painted around the radarchart

factorNames

public java.lang.String[] factorNames

names of the factors

factorColors

public ChartColor[] factorColors

color of the factor labels

factorMins

public double[] factorMins

minimum vaues of the factors.

factorMaxs

public double[] factorMaxs

maximum values ofd the factors.

factorFont

public ChartFont factorFont

font used to paint the factors

factorColor

public ChartColor factorColor

color used to paint the factors

gridStyle

public LineStyle gridStyle

grid's line style

gridFont

public ChartFont gridFont

grid's font

gridFontColor

public ChartColor gridFontColor

grid's font color

ticks

public int ticks

number of ticks in scale

tickLabelFormat

public java.lang.String tickLabelFormat

format of the tick labels

backStyle

public FillStyle backStyle

back style to fill the chart

pointColors

public ChartColor[] pointColors

color of the points. See also pointColorScale

pointColorScale

public double[] pointColorScale

ascending list of values used to select the color of the point. See also pointColors.
For example pointColors={Color.red,Color.white,Color.blue} and pointColorScale={10,20} will
- paint a red point if value is < 10 - paint a white point if value is >10 and < 20 - paint a blue point if value is > 20
