如何在MATLAB中绘制具有相对强度分数的节点列表

Question

我想在节点图上表示具有连接强度的互连节点的集合。

每个节点都有一个介于0和1之间的值矩阵，用于连接所有其他节点的强度，I.E：

[1.0000 0.1000 0.1200 0.0010]
[0.1000 1.0000 0.0820 0.0001]
...

其中列表示节点强度和行节点。

我希望在图表上放置节点是合理的 - 即一组强连接节点应该在图表上相对分组。

如何在Matlab中最简单地完成？我已经看过gplot，但我不确定它是否完全符合我的目标。

这是一个简单矩阵的例子：

Answer 1

我正在向你展示我的尝试，但不幸的是我还没有想到如何根据他们与其他人的距离来定义点的XY位置....

然而，我在这里留下一段代码，用于绘制您想要的类似图表，而不是节点的位置，以及强度＆＃34;我改变了它们之间的线条颜色。

对于更丰富多彩的绘图，您可以将灰度颜色更改为颜色图（即＆＃39; jet＆＃39;）。

我希望其他人能更好地解决它！

% your stegths are of 1,0.9 or 0 value. I suppose that in general you have
% 0-1 range, so just for this example, i am going to comvert the 0.9 into
% 0.5, so you can see the changes in colour.
strengths(strengths>0&strengths<1)=0.5; 

w=sum(strengths,2);
w=w/max(w);

% I dont have any idea how to do this....
% so I will create random points. Sorry :(
XY=rand(size(strengths,1),2);


isconect=strengths>0;
h=figure
hold on
for ii=1:size(strengths,1)
    plot(XY(ii,1),XY(ii,2),'k.','markersize',50*w(ii))

    for jj=1:sum(isconect(ii,:))-1
        idx=find(isconect(ii,:));
        idx=idx(jj+1);
        wc=strengths(ii,idx);
        plot([XY(ii,1) XY(idx,1)],[XY(ii,2) XY(idx,2)],'color',ones(3,1)*(1-wc),'linewidth',2*wc)
    end
end
set(gcf, 'Color', [1,1,1]);

axis off;

编辑：为了避免在圆圈上绘制线条，只需更改绘图的顺序（即绘制线条后的点）。我很糟糕，我只是匆忙做到了。
