# 泳道图(Swimlane)
|
||
|
||
适用于:跨角色/跨系统的端到端流程(用户/网关/服务/存储/回调)、多泳道协作流程、系统交互链路图。
|
||
|
||
支持两种方向:
|
||
- **水平泳道**:泳道为横向条带(自上而下排列),流程从左到右推进
|
||
- **垂直泳道**:泳道为纵向列(自左向右排列),流程从上到下推进
|
||
|
||
## Content 约束
|
||
|
||
- 泳道数(lanes)建议 3-7,超过 7 会显著降低可读性;如必须更多泳道,优先合并同类或拆成两张图
|
||
- 阶段数(stages)建议 4-8;超过 8 优先合并相邻阶段或改成“代表性阶段”
|
||
- 每个阶段在每条泳道中最多放 1 个“主步骤卡片”;如同一阶段需要多个步骤,放在同一格内做纵向堆叠(2-3 个为上限)
|
||
- 节点文本 1-2 行为主;长文本用 `\n` 手动换行,避免单行超长导致卡片过宽
|
||
- 仅画必要连线:泳道图的结构已经表达了“属于哪个角色/系统 + 发生顺序”,连线只用于表达跨泳道交互、关键因果关系或异步事件流
|
||
|
||
## Layout 选型
|
||
|
||
| 模式 | 适用条件 | 特征 |
|
||
|------|---------|------|
|
||
| **水平泳道** | 默认推荐;流程天然左→右推进 | lanes=行,stages=列;跨泳道同一阶段严格 x 对齐 |
|
||
| **垂直泳道** | 用户明确要求竖版、或画布更适合纵向滚动阅读 | lanes=列,stages=行;跨泳道同一阶段严格 y 对齐 |
|
||
|
||
## Layout 规则
|
||
|
||
### 通用规则(两种方向都适用)
|
||
|
||
1. **网格对齐是第一优先级**:跨泳道同一阶段必须严格对齐(水平对齐 x;垂直对齐 y)。对齐通过“共享阶段标尺(stage ruler / stage slots)”实现,不靠肉眼估算,也不靠逐节点随意手写坐标
|
||
2. **只生成真实节点**:为保证跨泳道阶段严格对齐,所有阶段统一保留透明的 **stage cell**;仅在真实阶段的 cell 内生成卡片节点,并按阶段索引映射到对应槽位
|
||
3. **泳道底色**:为了增强层级感同时保持界面整洁,**强烈建议所有泳道容器统一使用极浅灰色背景**(如 `fillColor: "#F8F9FA"` 或 `"#FCFCFC"`)。边框使用浅灰色细虚线(`borderDash: "dashed"`, `borderWidth: 1`, `borderColor: "#DEE0E3"`)以明确边界。
|
||
4. **步骤卡片**:使用 `rect`。为建立清晰的视觉层级,卡片**必须填充浅色背景**(参考 `elements/style.md` 中的浅色板,如极浅的主题色),边框使用对应的主题主色(`borderWidth: 1-2`),文字使用深色(如 `#1F2329`)以确保可读性。统一圆角;宽高以可读为先,避免过窄导致换行过多
|
||
5. **间距**:只要存在 connector 连线,卡片之间的主轴间距必须满足 `gap >= 40`
|
||
|
||
### 子节点对齐
|
||
|
||
- **同一阶段必须严格对齐**:所有泳道复用同一套 stage slots;不允许靠卡片自身宽度或肉眼估算来对齐
|
||
- **卡片宽度一致**:同一泳道中的步骤卡片应保持统一宽度;推荐使用统一固定宽度,或严格复用同一槽位宽度
|
||
- **统一使用 stack 容器**:有内容的阶段统一使用 `layout: "vertical"` 的 stack frame(纵向堆叠 1-3 张卡片);空阶段不生成 stack/卡片,但保留透明 cell 保证对齐
|
||
- **垂直居中但不影响对齐**:stage cell 默认 `alignItems: "stretch"`,可用 `justifyContent: "center"` 让卡片在 cell 内居中,以确保左右边界严格对齐
|
||
- **不靠底色区分行/列**:阶段网格默认不需要背景色;如需“轻微”的行/列边界提示,优先给 stage cell 加 1px 细边框(`fillColor: "transparent"` 仍保持视觉透明)
|
||
|
||
### Flex 栅格模式(默认)
|
||
|
||
- lane body 使用 Flex 布局:水平泳道用 `layout: "horizontal"`,垂直泳道用 `layout: "vertical"`
|
||
- 为每个阶段生成一个 **stage cell**(占位单元格);空阶段的 cell 透明但保留;cell 内用 `layout: "vertical"` 的 stack 承载 1-3 张卡片
|
||
- 统一参数:`slotWidth: 180-220`(水平泳道 cell 宽度)、`slotHeight: 64-104`(垂直泳道 cell 高度建议档)、`gap: 40-56`(有连线时必须 ≥40)、`stackGap: 8`、`lanePadding: 16`
|
||
- 对齐规则:所有泳道复用同一组 `slotWidth/slotHeight/gap`;同一阶段在各泳道上使用相同的 cell 索引保证严格对齐
|
||
- 尺寸语义:lane body `width/height` 用 `"fit-content"`(Yoga 自适应);卡片 `height: "fit-content"`;Flex 容器内不写子节点 `x/y`
|
||
- 内容密度:卡片文字 1-2 行;同阶段堆叠上限 2-3;超过上限优先拆分到相邻阶段或缩短文本
|
||
|
||
### 跨泳道间距(lanesGap)
|
||
|
||
- 根容器承载所有泳道:水平泳道用 `layout: "vertical"`,垂直泳道用 `layout: "horizontal"`
|
||
- 缩减跨泳道主轴间距 `lanesGap`(建议 `16-24`),以保持整体图表的紧凑性。避免 `lanesGap` 设置为 `0` 导致边框重叠变粗,也避免间距过大导致视觉涣散。
|
||
- 每条泳道作为根容器的子 frame,内部再使用上述 Flex 栅格的 stage cell 布局
|
||
- `lanesGap` 与 `lanePadding/stackGap` 独立;lane 内容增减不应影响跨泳道间距
|
||
- 4px 基线对齐:`lanesGap`、`lanePadding`、cell 尺寸建议按 4 的倍数对齐
|
||
|
||
### 水平泳道(lanes=行,stages=列)
|
||
|
||
- 根容器:`layout: "vertical"`,`gap: lanesGap` 固定;`alignItems: "stretch"`,标题在最上方
|
||
- 每条泳道:一个可见 frame(分组容器),内部用 `layout: "horizontal"` 分成两块:
|
||
- 左侧 lane label:固定宽度 text(如 100-140),垂直居中;左对齐(`textAlign: "left"`);title 需要比步骤卡片更醒目,优先通过 `fontSize: 18-20` + `fontWeight: "bold"` + 与泳道边框一致的 `textColor` 实现
|
||
- 右侧 lane body:`layout: "horizontal"`,包含完整的阶段 **stage cell** 数组;cell 宽度固定为 `slotWidth`,相邻 cell 间 `gap` 统一;空阶段 cell 透明但保留
|
||
- 步骤卡片:推荐统一卡片宽度(如 160-220),并在所有泳道复用同一组 `slotWidth / gap`,保证跨泳道阶段严格 x 对齐
|
||
|
||
### 垂直泳道(lanes=列,stages=行)
|
||
|
||
- 根容器:`layout: "horizontal"`,`gap: lanesGap` 固定;`alignItems: "stretch"`,标题在最上方
|
||
- 每条泳道:一个可见 frame(分组容器),内部 `layout: "vertical"`:
|
||
- 顶部 lane label:必须放在单独的 `lane label frame` 中,label frame 使用 `width: "fill-container"`、`alignItems: "center"`、`justifyContent: "center"`,并通过 `paddingTop` 留出与泳道上边的 gap(推荐 `12-16`,按 4px 基线取值,如 `padding: [12, 8, 8, 8]`);内部 text 使用 `width: "fill-container"` + `textAlign: "center"`,确保 title 在整条泳道顶部**水平居中**
|
||
- lane body:`layout: "vertical"`,包含完整的阶段 **stage cell** 数组;cell 高度固定为 `slotHeight`,相邻 cell 间 `gap` 统一;空阶段 cell 透明但保留
|
||
- 内容居中对齐:stage cell 建议 `alignItems: "center"` + `justifyContent: "center"`,让卡片在每个 cell 内水平/垂直居中;卡片宽度不超过 `slotWidth`(或固定宽度),避免被 `"fill-container"` 拉伸导致“看起来不居中”
|
||
- 步骤卡片:推荐统一卡片高度或统一 `slotHeight / gap`,保证跨泳道阶段严格 y 对齐
|
||
- 泳道外层容器必须显式写 `fillColor: "#F8F9FA"`(极浅灰)、`borderDash: "dashed"`、`borderWidth: 1`、`borderColor: "#DEE0E3"`(统一浅灰色),否则会被编译为虚拟 frame 导致不渲染
|
||
- 统一高度(Flex 自适应,可选):根容器使用 `alignItems: "stretch"`,每个泳道外层 frame 使用 `height: "fill-container"`;泳道内部仍保持 lane label + lane body 的结构

|
||
]
|
||
}
|
||
```
|
||
|
||
### 泳道配色(默认色板)
|
||
|
||
- **泳道背景**:所有泳道容器统一使用极浅灰色(如 `fillColor: "#F8F9FA"` 或 `"#FCFCFC"`),以增强物理容器的层级感,并突出内部的彩色卡片。
|
||
- **泳道边框**:所有泳道外层容器统一使用浅灰色细虚线(`borderColor: "#DEE0E3"`, `borderWidth: 1`, `borderDash: "dashed"`)。
|
||
- **泳道标题**:按 `elements/style.md` 经典色板为每条泳道分配不同的主题色,泳道 title 的 `textColor` 使用该主题色。
|
||
- **内容节点(rect)**:采用“浅色底 + 主题色边框”策略。`fillColor` 使用与该泳道主题色对应的极浅色(如浅蓝、浅紫等),`borderColor` 使用对应的主题色,文字 `textColor` 统一使用深色 `#1F2329`。
|
||
- **连线(connector)**:连线颜色固定为灰色 `#BBBFC4`,不随泳道颜色变化。当连线带有文字(`label`)时,为防止文字压在边框上难以阅读,必须为连线文字设置纯白背景(`labelFillColor: "#FFFFFF"`)遮挡底纹。
|
||
|
||
提醒:避免创建“虚拟 frame”(见 `elements/schema.md` 的说明)。lane 外层必须具有可见属性以避免在编译时被跳过。
|
||
|
||
|
||
## 连线规则(强制参考 connectors.md)
|
||
|
||
泳道图中所有连线的选择与写法必须严格遵循 `elements/connectors.md`,尤其是:
|
||
- `connector` 必须放在 `WBDocument.nodes` 顶层,不能嵌套在 `children`
|
||
- 默认优先使用自动绕线:`lineShape: "polyline"` / `"rightAngle"`,且不写 `waypoints`
|
||
- 未指定 `lineShape` 时默认使用 `"rightAngle"`
|
||
- 只有在必要时才强制锚点方向;锚点选择必须与节点相对位置一致
|
||
- 有连线时卡片间距必须满足 `gap >= 40`;如果连线包含文字(`label`),主轴间距必须 `gap >= 64`
|
||
- 带文字的连线必须设置 `labelFillColor: "#FFFFFF"` 遮挡底纹
|
||
|
||
泳道图语境下的落地约束:
|
||
- **默认不写锚点**,交给引擎自动推断;只有需要强制“左→右推进 / 上→下推进”时才写
|
||
- 需要表达“异步/事件流/推送”(如 SSE/Chunk)时:使用 `lineStyle: "dashed"` 并配合 `label` 说明语义;其他参数仍按 connectors.md
|
||
- 避免连接“仅用于布局且可能被优化掉的虚拟 frame”,尽量连接具体步骤卡片的节点 id(参考 `elements/schema.md` 的虚拟 frame 陷阱)
|
||
|
||

]

||
}
|
||
```
|
||
|
||
- 垂直泳道示例:见上文“垂直泳道”
|
||
|
||
- 全泳道统一 `slotWidth/slotHeight/gap`,并为每个阶段生成占位 **stage cell**(空阶段 cell 透明但保留)
|
||
- Flex 容器内不写子节点 `x/y`;对齐通过 cell 索引与统一尺寸实现
|
||
- 只有真实阶段才在对应 cell 内生成卡片;空阶段不生成卡片但保留 cell 保证网格完整
|
||
- 连线必须放在 `nodes` 顶层,并连接具体步骤卡片 id,不要连接 `lane-*-body` 这类布局容器
|
||
- **水平泳道**:根容器用 `layout: "vertical"` 固定 `lanesGap`;lane body 用 `layout: "horizontal"`;cell 固定宽度 `slotWidth`;主轴 `gap` 统一
|
||
- **垂直泳道**:根容器用 `layout: "horizontal"` 固定 `lanesGap`;lane body 用 `layout: "vertical"`;cell 固定高度 `slotHeight`;主轴 `gap` 统一
|
||
- **泳道 title**:title 比步骤卡片更醒目,但仍只用字号、字重、文字色强调;不要给泳道 title 额外加背景条
|
||
|
||
## 陷阱
|
||
|
||
- **各泳道复用的 stage slots 不一致**:会导致同阶段错位;`slotWidth / slotHeight / gap` 必须全泳道统一
|
||
- **把 connector 放进 children**:会导致 schema 报错或无法连线(见 connectors.md)
|

- **把辅助容器画成可见元素**:lane body 或其他支撑 frame 必须保持 `fillColor: "transparent"`,除泳道分组容器外不要额外加边框

- **连线过多**:按 connectors.md 的连线数量策略降采样,否则跨泳道线会互相遮挡导致不可读
