我想要一个在同一个图表中具有垂直和水平布局的图表。我怎样才能在 gojs 中实现这一点？

有很多方法可以实现你的目标。我能想到三个副手。按工作降序排列：

  • 创建一个自定义布局，做你想要的。这是最通用的，并且可能与您与您想要组合的两个现有图表一起使用的数据结构最兼容。
  • 在您的情况下，您可能可以使用扩展目录中的TableLayout ：http: //gojs.net/latest/extensions/Table.html。您可能可以继续使用Group s，但您会将其Group.layout设置为 null 以便在执行布局时完全忽略它们。
  • 将现有图表中的所有内容放入一个组中，并将其他现有图表中的所有内容放入另一个组中。第一个图的Diagram.layout将是第一组的Group.layout ，第二个图的Diagram.layout将是第二组的Group.layout。

请注意，每个图表只能有一个模型（Diagram.model），因此对于所有三种技术，您需要将所有数据添加到单个模型中，而不会混淆它们之间的引用。这意味着您需要确保节点的键都是唯一的。

这是一个示例，说明如何使用第三种技术将两个单独的图表放入一个图表中。我将从 Minimal 示例的两个副本开始，http ://gojs.net/latest/samples/minimal.html ，其中唯一的变化是一个具有ForceDirectedLayout而另一个具有LayeredDigraphLayout。因此将定义一个：

myDiagram = $(go.Diagram, "myDiagramDiv",
              {
                initialContentAlignment: go.Spot.Center,
                layout: $(go.ForceDirectedLayout),
                "undoManager.isEnabled": true
              });

另一个将被定义：

myDiagram = $(go.Diagram, "myDiagramDiv",
              {
                initialContentAlignment: go.Spot.Center,
                layout: $(go.LayeredDigraphLayout),
                "undoManager.isEnabled": true
              });

但除此之外，这两个图与最小样本完全一样。

最初，Minimal 的每个模型由以下人员创建：

myDiagram.model = new go.GraphLinksModel(
[
  { key: "Alpha", color: "lightblue" },
  { key: "Beta", color: "orange" },
  { key: "Gamma", color: "lightgreen" },
  { key: "Delta", color: "pink" }
],
[
  { from: "Alpha", to: "Beta" },
  { from: "Alpha", to: "Gamma" },
  { from: "Beta", to: "Beta" },
  { from: "Gamma", to: "Delta" },
  { from: "Delta", to: "Alpha" }
]);

因此，我们首先需要创建一个组合模型，即两个模型相加。将它们组合在一起的一种方法是：

myDiagram.model = new go.GraphLinksModel(
[
  { key: "Alpha", color: "lightblue" },
  { key: "Beta", color: "orange" },
  { key: "Gamma", color: "lightgreen" },
  { key: "Delta", color: "pink" },
  { key: "Alpha2", color: "lightblue" },
  { key: "Beta2", color: "orange" },
  { key: "Gamma2", color: "lightgreen" },
  { key: "Delta2", color: "pink" }
],
[
  { from: "Alpha", to: "Beta" },
  { from: "Alpha", to: "Gamma" },
  { from: "Beta", to: "Beta" },
  { from: "Gamma", to: "Delta" },
  { from: "Delta", to: "Alpha" },
  { from: "Alpha2", to: "Beta2" },
  { from: "Alpha2", to: "Gamma2" },
  { from: "Beta2", to: "Beta2" },
  { from: "Gamma2", to: "Delta2" },
  { from: "Delta2", to: "Alpha2" }
]);

再次，我会提到，无论您使用哪种技术，这都是您需要做的工作。大概您已经这样做了，只是想知道如何处理两种布局。

我建议的第三种技术使用Group来封装最初在整个Diagram中的内容。因此，让我们将两个组添加到模型中，并将每个原始节点分配给相应的组：

myDiagram.model = new go.GraphLinksModel(
[
  { key: "FD", isGroup: true, category: "FD" },  // NEW
  { key: "LD", isGroup: true, category: "LD" },  // NEW
  { key: "Alpha", color: "lightblue", group: "FD" },
  { key: "Beta", color: "orange", group: "FD" },
  { key: "Gamma", color: "lightgreen", group: "FD" },
  { key: "Delta", color: "pink", group: "FD" },
  { key: "Alpha2", color: "lightblue", group: "LD" },
  { key: "Beta2", color: "orange", group: "LD" },
  { key: "Gamma2", color: "lightgreen", group: "LD" },
  { key: "Delta2", color: "pink", group: "LD" }
],
[
  { from: "Alpha", to: "Beta" },
  { from: "Alpha", to: "Gamma" },
  { from: "Beta", to: "Beta" },
  { from: "Gamma", to: "Delta" },
  { from: "Delta", to: "Alpha" },
  { from: "Alpha2", to: "Beta2" },
  { from: "Alpha2", to: "Gamma2" },
  { from: "Beta2", to: "Beta2" },
  { from: "Gamma2", to: "Delta2" },
  { from: "Delta2", to: "Alpha2" }
]);

现在我们只需要定义每个组/类别/模板：

myDiagram.groupTemplateMap.add("FD",
  $(go.Group, "Auto",
    { layout: $(go.ForceDirectedLayout) },
    $(go.Shape, { fill: "white", stroke: "lightgray" }),
    $(go.Placeholder, { padding: 10 })
  ));

myDiagram.groupTemplateMap.add("LD",
  $(go.Group, "Auto",
    { layout: $(go.LayeredDigraphLayout) },
    $(go.Shape, { fill: "white", stroke: "lightgray" }),
    $(go.Placeholder, { padding: 10 })
  ));

出于本演示的目的，每种组的视觉外观细节无关紧要，就像节点和链接的外观细节无关紧要一样。对您而言重要的是一个组模板使用一种布局，另一个使用不同的布局，有两个组数据对象，并且所有节点数据都分配给适当的组。

在这种情况下，每个组模板都被用作单例，但也许您的要求将导致使用多个组模板中的任何一个或所有模板。

现在您只需要指定Diagram.layout来控制两组相对于彼此的排列方式。也许最简单的方法是使用GridLayout：

myDiagram = $(go.Diagram, "myDiagramDiv",
              {
                initialContentAlignment: go.Spot.Center,
                layout: $(go.GridLayout, { wrappingColumn: 1 }),
                "undoManager.isEnabled": true
              });

当然，您可以根据需要以任何方式自定义布局，包括使用完全不同的布局或自定义布局。

这是完整的代码。为简洁起见，我从原始 Minimal 示例中删除了一堆评论：

我是GoJs的新手，但我试过这个。
