Hey, 本人自主开发的弦图绘制工具迎来2.1.0版本了：起因是有粉丝问我前两天发布的文章中这张图咋画：
我本来一想我开发的工具画弦图还是很简单的哇（下面文章中有基本用法）
https://slandarer.blog.csdn.net/article/details/126458181
但是仔细一观察发现，这个弦图还有点不一样，同一个弧形块不同弦的末端颜色还不一样，我以前发布的版本是没有这个功能的，因此极速进行了一波开发：新增了两个功能函数
- setEachSquareF_Prop(m,n,...)
- setEachSquareT_Prop(m,n,...)
比如setEachSquareF_Prop(m,n,...)就是设置由下方第m个弧形块流向上方第n个弧形块的弦的下方末端的小弧形块的属性的。
显然setEachSquareT_Prop(m,n,...)就是设置由下方第m个弧形块流向上方第n个弧形块的弦的上方末端的小弧形块的属性的。
绝知此事要躬行，我们直接在例子里来看叭，本期绘制效果（绘图中所使用的数据为随机生成的，并非论文原始数据）：

教程部分
1 数据准备及基础绘图
随机生成一个数值矩阵，自定义流入流出变量名(colName, rowName)，然后直接绘图
matlab
rng(3)
% 随机生成数值矩阵
dataMat = randi([1, 15], [7, 22]);
dataMat(dataMat < 11) = 0;
dataMat(1, sum(dataMat,1) == 0) = 15;
colName = {'A2M', 'FGA', 'FGB', 'FGG', 'F11', 'KLKB1', 'SERPINE1', 'VWF',...
'THBD', 'TFPI', 'PLAT', 'SERPINA5', 'SERPIND1', 'F2', 'PLG', 'F12',...
'SERPINC1', 'SERPINA1', 'PROS1', 'SERPINF2', 'F13A1', 'PROC'};
rowName = {'Lung', 'Spleen', 'Liver', 'Heart',...
'Renal cortex', 'Renal medulla', 'Thyroid'};
figure('Units','normalized', 'Position',[.02, .05, .6, .85])
CC = chordChart(dataMat, 'rowName',rowName, 'colName',colName, 'Sep',1/80, 'LRadius',1.21);
CC = CC.draw();
% 旋转标签
CC.labelRotate('on')
2 修改上方弦末端小弧形块颜色
随机生成一个所有元素都是1,2的矩阵，然后比如第i行第j列是1，就为由下方弧形块i流向上方弧形块j的弦末端的小弧形块上第一种颜色：
matlab
% 单独设置每一个弦末端方块(Set individual end blocks for each chord)
% Use obj.setEachSquareF_Prop
% or obj.setEachSquareT_Prop
% F means from (blocks below)
% T means to (blocks above)
CListT = [173,70,65; 79,135,136]./255;% 配色
% Upregulated:1 | Downregulated:2
Regulated = rand([7, 22]);
Regulated = (Regulated < .8) + 1;
for i = 1:size(Regulated, 1)
for j = 1:size(Regulated, 2)
CC.setEachSquareT_Prop(i, j, 'FaceColor', CListT(Regulated(i,j),:))
end
end
3 绘制图例
由于弦图本身是没图例的，我们在坐标区域外面画俩小方块，并用这俩小方块的句柄生成不可变的图例：
matlab
H1 = fill([0,1,0]+100, [1,0,1]+100, CListT(1,:), 'EdgeColor','none');
H2 = fill([0,1,0]+100, [1,0,1]+100, CListT(2,:), 'EdgeColor','none');
lgdHdl = legend([H1,H2], {'Upregulated','Downregulated'}, 'AutoUpdate','off', 'Location','best');
lgdHdl.ItemTokenSize = [12,12];
lgdHdl.Box = 'off';
lgdHdl.FontSize = 13;
4 为下方方块及弦上色
看不懂的看看前面提到的基础教程：
matlab
% 修改下方方块颜色(Modify the color of the blocks below)
CListF=[128,108,171; 222,208,161; 180,196,229; 209,150,146; 175,201,166;
134,156,118; 175,175,173]./255;
for i=1:7
CC.setSquareF_N(i, 'FaceColor',CListF(i,:))
end
% 修改弦颜色(Modify chord color)
for i=1:7
for j=1:22
CC.setChordMN(i,j, 'FaceColor',CListF(i,:), 'FaceAlpha',.45)
end
