整了个大活，写了一个能够生成非常精致三元相图的函数，这种图主要用于展示三种变量之间的比例，本期实验绘制效果如下：   编写不易，这个工具写的脑壳痛，求多多点赞，依旧先介绍咋使用，工具函数放在最后，同时提供gitee及fileexchange下载链接，若是日后代码更改会在这俩仓库同步更改。 教程部分1 三元相坐标区域创建就一行代码就可以创建： % 初始化三元相图(Init ternary plot) STA1=STernary(); 2 set 设置坐标区域最基本属性set函数可以设置很多坐标区域属性，比如背景颜色Color： % 背景色变为灰色(Set the background color to gray) set(STA1,'Color',[.9,.9,.9]); 比如设置ABC三个轴标签A_Label,B_Label,C_Label的文本： % 设置标签文本(Set Label string) set(STA1,'A_Label','String','AAAAA') set(STA1,'B_Label','String','BBBBB') set(STA1,'C_Label','String','CCCCC') 3 基本绘图常见的 plot fill scatter contour contourf text 这些绘图函数都可以用，不过需要首字母大写并加个S，继续前面的代码往后写，画个散点图并增添图例： % 绘制散点图(Draw scatter plot) A=rand(1,20); B=rand(1,20); C=rand(1,20); STA1.SScatter(A,B,C,40,'filled','CData',[0,0,0]); legend() 4 set 设置其它属性ABC各个轴、主刻度、次刻度、主网格、次网格、轴标签、刻度标签全部可以由set函数设置，这里仅举A相关的例子，BC轴就把A字母换换就好： 以下两种设置方式等价： set(STA,'XXX','prop',.......)STA.set('XXX','prop',.......)% 设置A轴颜色和粗细(Set A_Axis's 'Color' and 'LineWidth') set(STA1,'A_Axis','Color',[0,0,.8],'LineWidth',3) % 设置A轴主网格颜色和粗细(Set A_Grid's 'Color' and 'LineWidth') set(STA1,'A_Grid','Color',[0,0,.8],'LineWidth',1.2) % 设置A轴次网格颜色线形 set(STA1,'A_MinorGrid','Color',[0,0,.8],'LineStyle','-.') % 设置A轴主刻度颜色 set(STA1,'A_Tick','Color',[0,0,.8]) % 设置A轴次刻度颜色 set(STA1,'A_MinorTick','Color',[0,0,.8]) % 设置A轴刻度标签字体和颜色 set(STA1,'A_TickLabel','Color',[0,0,.8],'FontSize',16) % 设置A轴标签字体和颜色及位置以及文本内容 set(STA1,'A_Label','Color',[0,0,.8],'FontSize',18,'Position',[.88,.6],'String',{'Ternary plot';'by Slandarer'}) 5 一些不常设置属性重新构造一个坐标区域对象叭，不用之前那个灰灰的啦，首先是将标签移动到侧面： STA2=STernary(); % 将标签移动到侧边(Move the label to the side) STA2.label2Side(); 设置主次刻度长度，设置刻度值/网格值/刻度标签文本： % 设置刻度长度(Set tick length) STA2.set('TickLenth',[.035,.02]) % 设置刻度值/网格值/刻度标签 % 'GridValues'/'TickValues' % 'MinorGridValues'/'MinorTickValues' % 'A_TickLabelStr'/'B_TickLabelStr'/'C_TickLabelStr' STA2.set('MinorGridValues',5:5:100) STA2.set('MinorTickValues',2.5:2.5:100) STA2.set('A_TickLabelStr',{'20%','40%','60%','80%','100%'}) 6 折线图基础绘图及绘图解读折线图使用SPlot函数绘制: % 初始化三元相图(Init ternary plot) STA=STernary(); % 绘制折线图及散点(Draw lines and scatter) STA.SPlot([2,2],[3,0],[5,8],'LineWidth',4,'Color',[.8,0,0]); STA.SPlot([2,7],[3,3],[5,0],'LineWidth',4,'Color',[0,.8,0]); STA.SPlot([2,0],[3,5],[5,5],'LineWidth',4,'Color',[0,0,.8]); STA.SScatter(2,3,5,180,'filled','CData',[1,1,1],'MarkerEdgeColor',[0,0,0],'LineWidth',2); % 绘制文本(Draw text) STA.SText(2+1,3,5,'(20%,30%,50%)','FontSize',16,'FontName','Cambria') 由图所示圆点比例为2:3:5那么平行于A轴网格的线会与A轴交在20%处，相应平行于B轴网格的线与B轴交在30%处。。。。。。同时实际上三条直线的长度也是呈2:3:5的比例的。 7 气泡图绘制非常简单就几行代码： % 初始化三元相图(Init ternary plot) STA=STernary(); % 随机构造数据(Randomly generated data) A=rand(1,50); B=rand(1,50); C=rand(1,50); sz=rand(1,50); % 绘制气泡图(Draw bubble chart) STA.SBubblechart(A,B,C,sz,'CData',A); 想改配色直接colormap即可： colormap(bone) 8 等高线图与填充等高线图绘图第四个参数是网格划分点数，若是填[]即为默认值分为90段计算核密度，正常画等高线图会填满整个三角： % 初始化三元相图(Init ternary plot) STA=STernary(); % 随机构造数据(Randomly generated data) A=rand(1,30); B=rand(1,30); C=rand(1,30); STA.SContourf(A,B,C,[],15,'LineWidth',1); 咋低于一定值不画呢，可以获取绘图的高度返回值Z，自定义要画等高线的高度： % 获取核密度范围并等分(Obtain the range of ksdensity and divide it equally) [~,Z]=STA.SContourf(A,B,C,[],15,'Visible','off'); levels=linspace(.5,max(max(Z)),15); % 依据等值线绘制等高线及等高线填充(Draw contour and contourf by levels) CfHdl=STA.SContourf(A,B,C,[],levels,'LineWidth',1); 多个绘图绘制图例可以直接legend()，但这里我们有一个被隐藏的contourf，建议直接把想要画在图例上的图形句柄放在一个矩阵里： legend([A,B,C],{'A','B','C'})% 获取核密度范围并等分(Obtain the range of ksdensity and divide it equally) [~,Z]=STA.SContourf(A,B,C,[],15,'Visible','off'); levels=linspace(.5,max(max(Z)),15); % 依据等值线绘制等高线及等高线填充(Draw contour and contourf by levels) CfHdl=STA.SContourf(A,B,C,[],levels,'LineWidth',1); CHdl=STA.SContour(A,B,C,[],levels,'LineWidth',1,'EdgeColor',[0,0,0]); SHdl=STA.SScatter(A,B,C,40,'filled','CData',[0,0,0]); % 绘制图例(Draw legend) legend([CfHdl,CHdl,SHdl],{'contourf','contour','scatter'},'FontSize',14,'FontName','Cambria')  改个颜色(这就是封面图)： colormap(turbo) 9 变量范围及凸包变量应该是非负的，建议自己先处理好数据，当然懒得写函数可以使用该工具自带的归一化工具： ABC=STA.SNorm(ABC)可以将每一列分别映射到0-1，每一列最小值映射到0，最大值映射到1. ABC=STA.SNormByLim(ABC,[Amin,Amax,Bmin,Bmax,Cmin,Cmax])该函数可以预先设置变量范围比如你的数据是0-50范围但是这组数据最大值就是45，那么SNorm函数会把45映射到1，但是SNormByLim函数就能把45映射到0.9。 变量范围映射并绘制散点图 % 初始化三元相图(Init ternary plot) STA=STernary(); % 随机构造数据(Randomly generated data) Pnt1=mvnrnd([10,30,10],[15 0 0;0 20 0;0 0 12],80); Pnt2=mvnrnd([30,10,15],[25 0 0;0 15 0;0 0 40],80); Pnt3=mvnrnd([25,10,35],[35 0 0;0 20 0;0 0 30],80); % 数据归一化(Normalization) Pnt1=STA.SNormByLim(Pnt1,[-5,50,-5,50,-5,50]); Pnt2=STA.SNormByLim(Pnt2,[-5,50,-5,50,-5,50]); Pnt3=STA.SNormByLim(Pnt3,[-5,50,-5,50,-5,50]); % 绘制散点图(Draw scatter) propCell={80,'filled','LineWidth',1,'MarkerEdgeColor',[1 1 1]*.3,'MarkerFaceColor'}; STA.SScatter(Pnt1(:,1),Pnt1(:,2),Pnt1(:,3),propCell{:},[0.4,0.76,0.65]); STA.SScatter(Pnt2(:,1),Pnt2(:,2),Pnt2(:,3),propCell{:},[1,0.55,0.38]); STA.SScatter(Pnt3(:,1),Pnt3(:,2),Pnt3(:,3),propCell{:},[0.55,0.63,0.8]);凸包绘制本来想让大家用被注释掉的写法，想了想还是算了，注释掉的写法依旧能用，但我将其内置了： % 已废弃写法(Obsolete method) % % 计算凸包(Get convhull) % [X1,Y1]=STA.ternData(Pnt1(:,1),Pnt1(:,2),Pnt1(:,3)); % [X2,Y2]=STA.ternData(Pnt2(:,1),Pnt2(:,2),Pnt2(:,3)); % [X3,Y3]=STA.ternData(Pnt3(:,1),Pnt3(:,2),Pnt3(:,3)); % [ind1,~]=convhull([X1,Y1]); % [ind2,~]=convhull([X2,Y2]); % [ind3,~]=convhull([X3,Y3]); % % % 绘制凸包(Draw convhull) % STA.SFill(Pnt1(ind1,1),Pnt1(ind1,2),Pnt1(ind1,3),[0.4,0.76,0.65],'FaceAlpha',.2,'LineWidth',2,'EdgeColor',[0.4,0.76,0.65]./2); % STA.SFill(Pnt2(ind2,1),Pnt2(ind2,2),Pnt2(ind2,3),[1,0.55,0.38],'FaceAlpha',.2,'LineWidth',2,'EdgeColor',[1,0.55,0.38]./2); % STA.SFill(Pnt3(ind3,1),Pnt3(ind3,2),Pnt3(ind3,3),[0.55,0.63,0.8],'FaceAlpha',.2,'LineWidth',2,'EdgeColor',[0.55,0.63,0.8]./2); % 绘制凸包(Draw convhull) STA.SConvhull(Pnt1(:,1),Pnt1(:,2),Pnt1(:,3),[0.4,0.76,0.65],'FaceAlpha',.2,'LineWidth',2,'EdgeColor',[0.4,0.76,0.65]./2); STA.SConvhull(Pnt2(:,1),Pnt2(:,2),Pnt2(:,3),[1,0.55,0.38],'FaceAlpha',.2,'LineWidth',2,'EdgeColor',[1,0.55,0.38]./2); STA.SConvhull(Pnt3(:,1),Pnt3(:,2),Pnt3(:,3),[0.55,0.63,0.8],'FaceAlpha',.2,'LineWidth',2,'EdgeColor',[0.55,0.63,0.8]./2); % 绘制图例(Draw legend) legend({'Data1','Data2','Data3','convex1','convex2','convex3'},'FontSize',14,'FontName','Cambria') 10 利用nan同时绘制多条折线没错我也考虑了减少循环的一些措施，工具函数支持适当加入nan将折线断开以同时绘制多条折线： % 初始化三元相图(Init ternary plot) STA=STernary(); A=rand(1,20); B=rand(1,20); C=rand(1,20); A=[A;A*0+mean(A);A.*nan]; B=[B;B*0+mean(B);B.*nan]; C=[C;C*0+mean(C);C.*nan]; % 绘制折线图(Draw Line) STA.SScatter(A,B,C,40,'filled','CData',[0,0,0]); % 绘制散点图(Draw scatter plot) STA.SPlot(A(:),B(:),C(:),'LineWidth',1,'Color',[0,0,0]); 工具函数完整代码classdef STernary >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
