MATLAB | 绘图复刻(十四) | 右侧对齐桑基图，及工具函数SSankey更新

hey 真的好久不见了，本期既是一期绘图复刻教程，也是我写的工具函数的版本更新，本期复刻的图片来自《Nature》：

0 数据

本文所使用的数据大概长这样，存储在.mat文件中：

load('natureRandData.mat')

该文件依旧可以在文末所示仓库获取，当然这组数据是通过以下方式随机生成的，直接复制以下代码也是可以的：

% rng(5)
% SourceValue=[60,40,30];
% LayerNum=[3,10,10,10,10,10,6,1];
% links{1,3}='';
% for k=1
%     TargetValue=zeros(1,LayerNum(k+1));
%     for i=1:LayerNum(k)
%         tValue=randi([1,13],[1,LayerNum(k+1)]);
%         tValue=tValue./sum(tValue).*SourceValue(i);
%         for j=1:LayerNum(k+1)

1 配色

配色数据就是随便找个颜色提取器提取的论文原图：

CList1=[233,163,117; 150,209,224; 78 ,115,180]./255;
CList2=[149, 77, 85; 182, 85, 90; 208, 91, 94;
        208, 91, 94; 245,124,112; 252,150,128;
        252,173,151; 253,196,176; 253,217,203;
        254,236,228; 230,230,230]./255;

2 基础绘图

% 创建桑基图对象(Create a Sankey diagram object)
SK=SSankey(links(:,1),links(:,2),links(:,3));

% % 类似于向右侧对齐
% SK.LayerOrder='reverse';

% 修改链接颜色渲染方式(Set link color rendering method)
% 'left'/'right'/'interp'(default)/'map'/'simple'
SK.RenderingMethod='left';  

% 修改对齐方式(Set alignment)
% 'up'/'down'/'center'(default)
SK.Align='center';

% 修改文本位置(Set Text Location)
% 'left'(default)/'right'/'top'/'center'/'bottom'
SK.LabelLocation='right';

% 设置缝隙占比(Separation distance proportion)
SK.Sep=0.02;
% SK.Sep=[.08,.04,.02,.05,.05,.06,.07];

% 设置方块占比(Set the scale of blocks)
% BlockScale>0 & BlockScale<1
SK.BlockScale=.16;

% 设置颜色(Set color)
SK.ColorList=[
    CList1;
    CList2(1:11,:)
    CList2(1:11,:)
    CList2(1:11,:)
    CList2(1:11,:)
    CList2(1:10,:)
    CList2(1:6,:)
    CList2(1,:)
    ];

% 开始绘图(Start drawing)
SK.draw()

---

3 右侧对齐

我们发现此时有的Residual方块由于左侧没有方块会被排列在最左侧，这样会比较混乱，此时选择将LayerOrder设置为反方向(此操作要在SK.draw()之前)：

% 类似于向右侧对齐
SK.LayerOrder='reverse';

---

4 自定义缝隙比例

我们发现由于流入流出数据不相等，越往右侧整体会越窄，而原图基本上是两端对齐的，因此我们可以调整每一层的缝隙占比，比如(此操作要在SK.draw()之前)：

% 设置缝隙占比(Separation distance proportion)
% SK.Sep=0.02;
SK.Sep=[.08,.04,.02,.05,.05,.06,.07];

---

5 节点方块修饰

加个白框：

for i=1:SK.BN
    SK.setBlock(i,'EdgeColor',[1,1,1],'LineWidth',1)
end

---

6 添加标签

就直接用text硬画，第i层的横坐标就是i，而宽度是SK.BlockScale，因此比较容易找到每层的X方向中点：

FontCell={'FontSize',22,'FontName','Times New Roman','HorizontalAlignment','center','VerticalAlignment','bottom'};
for i=2:SK.LN-1
    text(i+SK.BlockScale/2,min(min(SK.LayerPos(:,3:4))),['H',num2str(i-1)],FontCell{:})
end
text(1+SK.BlockScale/2,min(min(SK.LayerPos(:,3:4))),'Input',FontCell{:})
text(8+SK.BlockScale/2,min(min(SK.LayerPos(:,3:4))),'OutCome',FontCell{:})
