Graphviz稀疏矩阵节点对齐

标签： vertical-alignment sparse-matrix graphviz

我试图用点语言绘制稀疏矩阵图，实际上节点连接没问题，但问题是这些节点的垂直对齐，我试图使用pos和放置x和y值的节点，但是只是没有工作（我认为是因为默认布局）。如果你能帮助我一个有压力的学生会感谢你。我的点代码低于下面，是生成图像的链接。

谢谢。

更接近所需稀疏矩阵的最重要工具是group：

  

<强>组

     

如果边缘的端点属于同一组，即具有相同的组属性，则设置参数以避免交叉并保持边缘平直。

由于稀疏矩阵非常稀疏，我也需要一些空节点。我还删除了[constraint = true]，因为它是默认值。我所做的更改是源代码中的注释：

digraph Sparce_Matrix {

    node [shape=box]

    /* add group 1 for vertical alignment */
    Mt[ label = "Matrix", width = 1.5, style = filled, fillcolor = firebrick1, group = 1 ];

    /* empty nodes, needed to override graphiz' default node placement */
    e0[ shape = point, width = 0 ];
    e1[ shape = point, width = 0 ];


    //(^< ............ ............ ............ ............ ............ U S U A R I O S
    /* groups added for vertical alignment */ 
    U0 [label = "Estructuras"    pos = "5.3,3.5!" width = 1.5 style = filled, fillcolor = bisque1, group = 1 ];
