basic drawing
The data is a numeric matrix:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC=RC.draw();
change style
There are Patchtwo Linestyles, Typeset the style by setting attributes:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X,'Type','Patch');
RC=RC.draw();
add modify label add legend
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC.PropName={'建模','实验','编程','总结','撰写','创新','摸鱼'};
RC.ClassName={'同门A','同门B','同门C','同门D'};
RC=RC.draw();
RC.legend();
R-axis position and its range
Change the range to [2,10], and draw 2, 8, 9, 10 four tick marks:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC.RLim=[2,10];
RC.RTick=[2,8:1:10];
RC=RC.draw();
RC.legend();
Modify axis properties
use:
- setThetaTick
- setRTick
Set the axis properties, for example, the theta axis becomes light red, and the R axis becomes light blue:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC=RC.draw();
RC.legend();
RC.setThetaTick('LineWidth',2,'Color',[.6,.6,.8]);
RC.setRTick('LineWidth',1.5,'Color',[.8,.6,.6]);
Modify label properties
use:
- setPropLabel
- setRLabel
Modify attribute labels and R tick labels:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC=RC.draw();
RC.legend();
RC.setPropLabel('FontSize',20,'FontName','Cambria','Color',[0,0,.8])
RC.setRLabel('FontSize',15,'FontName','Cambria','Color',[.8,0,0])
Modify the circular background
Decorate the background with setBkga function:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC=RC.draw();
RC.legend();
RC.setBkg('FaceColor',[0,0,.1])
RC.setRLabel('Color','none')
Cosmetic Polygon
The two types of polygons are drawn with Patchobjects and Lineobjects respectively. The decoration methods are slightly different, but they are all setPatchNdecorated with functions. The following is an example of modifying the color:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC=RC.draw();
RC.legend();
colorList=[78 101 155;
138 140 191;
184 168 207;
231 188 198;
253 207 158;
239 164 132;
182 118 108]./255;
for n=1:RC.ClassNum
RC.setPatchN(n,'Color',colorList(n,:),'MarkerFaceColor',colorList(n,:))
end
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X,'Type','Patch');
RC=RC.draw();
RC.legend();
colorList=[78 101 155;
138 140 191;
184 168 207;
231 188 198;
253 207 158;
239 164 132;
182 118 108]./255;
for n=1:RC.ClassNum
RC.setPatchN(n,'FaceColor',colorList(n,:),'EdgeColor',colorList(n,:))
end
