Radarchart configuration

This is a complete example of a radar chart:

radarPlotter=new RadarPlotter();

 

serie1=new LineDataSerie(values,lstyle);
serie2=new LineDataSerie(values,lstyle);

serie1.valueFont=new Font(...);

 

 

serie1.fillStyle=FillStyle(Color.Blue);
serie1.drawPoint=true;

serie1.pointColor= Color.Blue;

radarPlotter.backStyle=new FillStyle(...);
radarPlotter.border=new LineStyle(...);
radarPlotter.faktorColor=java.awt.Color.black;
radarPlotter.faktorFont=new Font(...);
radarPlotter.faktorMaxs={100,100,100,100};
radarPlotter.faktorMins={0,0,0,0};
radarPlotter.faktorNames={"R & D", ....};

radarPlotter.gridStyle=new LineStyle(...);
radarPlotter.gridFont= new Font(...);
radarPlotter.gridFontColor=java.awt.Color.gray;
radarPlotter.radiusModifier=0.8;

 

It is also possible to have more than 4 factors (axis). In the following example we have a new axis called "NEW" whose scale is different from the others, 0 to 200.

 
Parameters
Description
Equivalent Java[TM] class/property
  SERIE_DATA_1=12|73|50|95|120 SERIE_DATA_2=20|41|60|10|20 RADARCHART_FAKTOR_MAX=100|100|100|100|200 RADARCHART_FAKTOR_MIN=0|0|0|0|0 RADARCHART_FAKTOR_NAMES=R & D|Distribution|Marketing|other|NEW

Values to plot (series 2).

Min. values of the axis (faktors)
Names of faktors

See above

 

It is also possible to have a circular radar chart using the following parameters:

 
Parameters
Description
Equivalent Java[TM] class/property
 

RADARCHART_CIRCLE=TRUE
RADARCHART_TICKS=4 RADARCHART_FAKTOR_COLOR=0xff0000 RADARCHART_FAKTOR_FONT=Dialog|ITALIC|12

Circular chart
Number of lines in grid (defualt is 5)
Color of faktors' names is RED
Font os faktors' names

radarPlotter.drawCircle=true;
radarPlotter.ticks=4;

 

You can use different colors for each factor name using the following parameter:

 
Parameters
Description
Equivalent Java[TM] class/property
 

RADARCHART_FAKTOR_COLORS=RED|BLUE|GREEN|GRAY|BLACK

List of colors

radarPlotter.faktorColors

 

The following 2 parameters allows you to change the color of the points, depending on the value:

 

Example:

 
Parameters
Description
Equivalent Java[TM] class/property
 

RADARCHART_POINT_COLORS_SCALE=20|40|60|80 RADARCHART_POINT_COLORS=0xffff00|0xffc800|0xff0000|0xcc3333|0x0

Scale
Colors

radarPlotter.pointColorsScale
radarPlotter.pointColors

values under 20 will have a yellow point, values between 20 and 40 will have an orange color, values beetwen 40 and 60 will have a red color, values beetwen 60 and 80 will have a dark red color and values above 80 will have a black point.
