绘制效果
教程部分
基础绘制
数据为数值矩阵即可：
X=randi([2,8],[4,7])+rand([4,7]); RC=radarChart(X); RC=RC.draw();
改变样式
有Patch和Line两种样式，通过设置Type属性设置样式：
X=randi([2,8],[4,7])+rand([4,7]); RC=radarChart(X,'Type','Patch'); RC=RC.draw();
添加修改标签添加图例
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轴位置及其范围
范围改为[2,10]，并绘制2,8,9,10四条刻度线:
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();
修改轴属性
使用:
- setThetaTick
- setRTick
设置轴属性，举个例子，theta轴变为淡红色,R轴变为淡蓝色:
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]);
修改标签属性
使用:
- setPropLabel
- setRLabel
修改属性标签和R刻度标签：
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])
修改圆形背景
使用setBkg函数修饰背景：
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')
修饰多边形
两种类型的多边形分别用Patch对象和Line对象绘制，修饰方式略有区别，不过都是使用setPatchN函数进行修饰，以下以修改颜色举例：
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
