目录绘制效果教程部分基础绘制改变样式添加修改标签添加图例R轴位置及其范围修改轴属性修改标签属性修改圆形背景修饰多边形工具函数完整代码绘制效果 教程部分 基础绘制 数据为数值矩阵即
数据为数值矩阵即可:
X=randi([2,8],[4,7])+rand([4,7]);
RC=radarChart(X);
RC=RC.draw();
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();
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();
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();
使用:
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]);
使用:
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])
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')
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
