# 画布概览 | ||
|
||
用户可在画布中可视化地探索图数据。本文主要介绍画布的组成及相关功能。 | ||
|
||
![canvas](../../figs/canvas-overview.png) | ||
|
||
画布的组成如下: | ||
|
||
- 顶部页签 | ||
- 可视化模式 | ||
- 数据存储 | ||
- 搜索框 | ||
- 多布局 | ||
- 缩略图 | ||
- 数据概览 | ||
|
||
## 顶部页签 | ||
|
||
用户可以通过单击画布顶部加号![canvas_tab](../../figs/list-add.png)图标同时操作多个画布。 | ||
|
||
![canvas_overview](../../figs/canvas-graphspace.png) | ||
|
||
- 不同画布上的数据可以来自同一个图空间也可以来自不同的图空间。 | ||
- 除了左边页签的第一个画布外,用户可以自定义画布的名称。 | ||
|
||
## 可视化模式 | ||
|
||
用户可以选择 **2D 模式**和 **3D 模式**可视化地在画布上探索图数据。更多信息,参见[可视化模式](visualization-mode.md)。 | ||
|
||
## 数据存储 | ||
|
||
用户可以通过创建快照,或以图片、CSV 文件的方式导出画布以存储当前画布数据。 | ||
|
||
在页面右上方单击![PNG](../../figs/topbar-exportPNG.png)以图片形式存储画布数据;单击![CSV](../../figs/topbar-exportCSV.png)以 CSV 文件的方式存储画布数据。 | ||
|
||
关于快照的更多信息,参见[画布快照](canvas-snapshot.md)。 | ||
|
||
## 搜索框 | ||
|
||
在页面左上方的搜索框中,输入 VID 或者 Tag 的属性值定位目标点。 | ||
|
||
## 多布局 | ||
|
||
Explorer 支持 6 中布局方式展示画布上的数据之间的关系。 | ||
|
||
| 力导向图 | 层次图 | 环形图 | 网格 | 神经网络 | 辐射 | | ||
| -------- | ------ | ------ | ----- | -------- | ----- | | ||
| ![graphView](../../figs/Thumbnail-graphView.png) | ![treeView](../../figs/Thumbnail-treeView.png) | ![sphereView](../../figs/Thumbnail-sphereView.png) | ![grid](../../figs/Thumbnail-Grid.png) | ![neural](../../figs/Thumbnail-neuralNetwork.png) | ![radial](../../figs/Thumbnail-Radial.png) | | ||
|
||
![layouts](../../figs/layout.gif) | ||
|
||
## 缩略图 | ||
|
||
全屏展示画布中的图,收起缩略图,缩小或放大画布中的图等。同时在缩略图的左下角显示了画布中的图占总图的百分比。 | ||
|
||
![](../../figs/thumbnail.png) | ||
|
||
## 数据概览 | ||
|
||
在页面右侧,单击![list-left](../../figs/list-left.png)展开数据概览面板。 | ||
|
||
![dataView](../../figs/dataview.png) | ||
|
||
- 可以在数据概览面板中看到画布中的 Tag 数、Edge type 数,及对应的点和边的数量。 | ||
- 在数据概览面板,单击 Tag 颜色图标,可自定义 Tag 相同的点的颜色、尺寸、图标。 | ||
|
||
!!! note | ||
Tag 完全相同的 VID 点的颜色相同。在画布中右键单击单个点可手动修改一个点的样式。 |

# 管理快照 | ||
|
||
Explorer 的快照功能可保存图探索得到的可视化结果,以便再次打开浏览器时还原保存的图数据。 | ||
|
||
## 创建快照 | ||
|
||
1. 在画布右上角,单击相机![snapshot](../../figs/graph-snapshot.png)图标。 | ||
2. 填写快照名称和备注(选填)。 | ||
3. 单击**提交**。 | ||
|
||
!!! note | ||
|
||
已创建的快照被存放在历史快照中。更多信息,参见下文。 | ||
|
||
|
||
## 历史快照 | ||
|
||
在 Explorer 页面左侧导航栏,单击![snapshot_history](../../figs/snapshot-history.png)图标进入历史快照列表页面。用户可切换图空间查看相应图空间的历史快照,还可以导入历史快照至画布,下载历史快照至本地,以及删除快照。 | ||
|
||
在目标历史快照右侧的**操作**列下: | ||
|
||
- 单击![snapshot_import](../../figs/snapshot-import.png)导入历史快照至新画布中。 | ||
- 单击![snapshot_export](../../figs/snapshot-export.png)导出历史快照至本地。 | ||
- 单击![snapshot_delete](../../figs/snapshot-delete.png)删除历史快照。 | ||
|
||
!!! note | ||
|
||
目前最多存储 50 个历史快照。 | ||

# 可视化模式 | ||
|
||
Explorer 支持 **2D** 和 **3D** 2 种可视化模式探索数据。2D 模式支持数据查看和图操作;3D 模式通过不同视角对图数据进行探索,适用于数据量级比较高或者需要演示的场合。 | ||
|
||
!!! note | ||
|
||
3D 模式下,不可进行图数据的操作。 | ||
|
||
![visualizaiton_mode](../../figs/visualization.gif) | ||
|
||
## 2D 模式 | ||
|
||
2D 模式下可对画布上的数据进行探索操作: | ||
|
||
![2D](../../figs/2d-mode.png) | ||
|
||
| 参数 | 说明 | | ||
| ---------- | ------------------------------------------------------------ | | ||
| 出入度权重 | 根据画布中所有点的出边和入边的条数,自动调整点的大小。 | | ||
| 重置出入度 | 重置画布中的点至原始大小。 | | ||
| 信息检测 | 孤立点:检测画布中所有的无边点。<br />悬挂边:检测画布中只有一条无向边的点。<br />环检测:检测由边和点连接在一起形成循环的路径。 | | ||
|
||
有关更多的 2D 模式下可进行的操作,参见[画布功能](canvas-overview.md)。 | ||
|
||
|
||
## 3D 模式 | ||
|
||
![2D](../../figs/3d-mode.png) | ||
|
||
在页面左上方,单击视图切换开关可切换至 3D 视图模式。3D 视图模式下,可切换回到 2D 图探索模式,并且不会对 2D 的探索产生任何副作用。 | ||
|
||
| 参数 | 说明 | | ||
| -------- | ------------------------------------------------------------ | | ||
| 鸟瞰 | 以鸟瞰的方式展示当前图空间的所有数据(以最少 2 万点和 2 千边进行采样)。 | | ||
| 画质 | 高:节点以球的形式展示,光影效果更好。<br />低:节点以圆的形式展示,可以支持更大数据量。 | | ||
| 重新受力 | 当不同的点重叠时,可单击**重新受力**分散点与点之间的距离。 | | ||
|
||
!!! compatibility "历史版本兼容性" | ||
|
||
针对 3.0.0 以下版本的 Nebula Graph,需要创建索引后才可以使用鸟瞰功能。更多信息,参见[创建索引](../../../3.ngql-guide/14.native-index-statements/1.create-native-index.md)。 |
