graph - ArangoDB，如何显示图表？

Question

我是 arangoDB 新手。我创建文档集合“sitetestcom”和边缘集合“链接”。在 ArangoDB Web 界面中，我将图形查看器配置与顶点集合设置为 sitetestcom，将边缘集合设置为链接。但没有显示任何图形，只有 2 个顶点

如何显示图表？

预先感谢您的帮助。

集合:sitetestcom，类型:文档

Answer 1

我将您的集合导入到 ArangoDB 中。
请注意:文档集合不是有效的 JSON，因为数据中有一些星号 *，必须先将其删除。

针对当前的问题。

当您单击图表菜单时，您可以选择集合或图表，下面是一个“高级”框。如果您单击它，它将打开一个表单。有一些初始设置，您可以更改它们。 现在，无需更改此处的任何内容，单击开始。
您可能会看到一个顶点或一个空图。别担心。

默认情况下，图形查看器在开始时显示随机顶点，但您可以通过单击图形窗口右上角的“过滤器”图标来选择特定顶点。

单击此图标。
在现在应该出现的过滤器表单上，单击属性名称列表框并选择_key。
在属性值字段中，复制并粘贴此键:4140262281(这是附加到问题的文档集合中的顶点键)。
您现在应该已经得到一个由该顶点和其他 3 个顶点组成的小图，并通过边连接。

现在，如果您的数据有更多连接，您将能够单击顶点，任何连接的顶点也会显示出来。

您在上面的屏幕截图中只看到两个顶点的原因是，没有更多的边将其他顶点连接到这些顶点。

尝试在过滤器中输入顶点键(来自屏幕截图):4130431881。您应该再次只获得这两个。

现在，假设您想将此顶点连接到我之前向您展示的顶点。

1. 打开集合，进入链接集合并点击右上角的+按钮，以创建新的边缘文档。
2. 创建边缘:
   在_from字段中输入:sitetestcom/4140262281
   在_to字段中输入:sitetestcom/4130431881
   点击创建。

现在返回图形查看器并启动图形:再次按 _key == 4140262281 过滤。

您现在应该可以看到 4140262281 顶点和新连接的 4130431881 顶点。

现在，如果您单击 4140262281 顶点，则应显示其连接的顶点 4150682505。

最后，为了给顶点一个更加用户友好的命名(我采用了你的titre属性)，单击过滤器旁边的滚轮按钮，然后单击“vertices”-“label” '。 将 _key 条目替换为 titre 并点击更改。

您现在应该看到顶点的标题而不是 _key。

希望有所帮助。
