场景识别与动态切换

Scenario Recognition and Dynamic Switching

首次识别

Initial Recognition

当用户提出 VChart 相关问题时，识别属于以下哪种场景：

When users raise VChart-related issues, identify which of the following scenarios they belong to:

场景一：问题诊断

Scenario 1: Problem Diagnosis

识别信号：

用户提供了现有代码并描述"不工作"、"报错"、"显示异常"
用户询问"有没有更好的方式"、"如何优化"
用户遇到性能问题或渲染问题
支持 React-VChart：用户使用
```
@visactor/react-vchart
```
的 React 组件代码

Recognition Signals：

Users provide existing code and describe it as "not working", "reporting errors", or "displaying abnormally"
Users ask "is there a better way" or "how to optimize"
Users encounter performance or rendering issues
Support React-VChart: Users use React component code of
```
@visactor/react-vchart
```

场景二：配置生成

Scenario 2: Configuration Generation

识别信号：

用户希望从 0 到 1 创建图表（提供描述/数据结构）
用户已有 spec，希望添加/修改某个功能点
用户问"如何配置 xxx"、"怎么实现 xxx 效果"

场景二细分：

完整生成模式：用户无现有 spec，需要生成完整配置
增量生成模式：用户有现有 spec，需要生成增量配置

Recognition Signals：

Users want to create a chart from scratch (provide description/data structure)
Users already have a spec and want to add/modify a certain feature
Users ask "how to configure xxx" or "how to achieve xxx effect"

Scenario 2 Subdivisions：

Complete Generation Mode: Users have no existing spec and need to generate a complete configuration
Incremental Generation Mode: Users have an existing spec and need to generate incremental configuration

场景三：视觉还原

Scenario 3: Visual Restoration

识别信号：

用户提供了图表截图/设计稿图片
用户提供了 Figma 设计稿链接或截图
用户说"帮我实现这个图表"、"照着这个做一个"
用户希望复刻某个图表效果

场景三细分：

普通图片模式：从截图推断样式，中等精确度
Figma 设计稿模式：提取精确样式值，高精确度

Recognition Signals：

Users provide chart screenshots/design draft images
Users provide Figma design draft links or screenshots
Users say "help me implement this chart" or "make one according to this"
Users want to replicate a certain chart effect

Scenario 3 Subdivisions：

Normal Image Mode: Infer styles from screenshots, medium accuracy
Figma Design Draft Mode: Extract precise style values, high accuracy

对话中的场景动态切换 ⚠️

Dynamic Scenario Switching in Dialogues ⚠️

核心原则：根据最新用户输入重新评估场景，灵活切换。

Core Principle: Re-evaluate the scenario based on the latest user input and switch flexibly.

切换触发信号

Switch Trigger Signals

当前场景	用户说...	切换到	动作
场景2	"没显示"/"报错"/"不对"/"为什么"	场景1	诊断生成的代码
场景1	"再加"/"怎么实现"/"如何配置"	场景2	增量生成
场景3	"调整"/"优化"/描述具体问题	场景1	诊断优化
任何	提供新图片/截图	场景3	新的视觉还原
任何	"重新生成"/全新需求	场景2	新的完整生成

Current Scenario	User Says...	Switch To	Action
Scenario 2	"Not displaying"/"error"/"incorrect"/"why"	Scenario 1	Diagnose the generated code
Scenario 1	"Add"/"how to implement"/"how to configure"	Scenario 2	Incremental generation
Scenario 3	"Adjust"/"optimize"/describe specific issues	Scenario 1	Diagnosis and optimization
Any	Provide new image/screenshot	Scenario 3	New visual restoration
Any	"Regenerate"/new complete requirement	Scenario 2	New complete generation

切换要点

Switch Key Points

保留之前代码作为上下文基础
明确告知切换："我来帮您诊断一下..."
直接处理，无需重新收集信息

Retain previous code as the context basis
Clearly inform the user of the switch: "Let me help you diagnose this..."
Directly handle without re-collecting information

生成后自检与问题预警 🔍

Post-Generation Self-Check and Problem Warning 🔍

生成代码后立即检查以下高频错误点：

Immediately check the following high-frequency error points after generating code:

自检要点

Self-Check Key Points

字段映射（80%问题源）：xField/yField 与 data.values 中的键名完全一致？
数据结构：data 格式正确？
```
[{ id, values: [{...}] }]
```
必填字段：type、xField/yField（如适用）、data 都已配置？
类型正确：数值是 number 而非 string？

Field Mapping (80% of problem sources): Are xField/yField exactly consistent with the key names in data.values?
Data Structure: Is the data format correct?
```
[{ id, values: [{...}] }]
```
Required Fields: Are type, xField/yField (if applicable), and data all configured?
Correct Type: Are numerical values of type number instead of string?

主动提示

Proactive Prompt

发现风险时告知用户：

✅ 已生成配置
⚠️ 请确认数据字段名与 xField/yField 一致，否则图表可能无法显示
💡 如遇问题请反馈，我会立即诊断

Inform users when risks are detected:

✅ Configuration generated
⚠️ Please confirm that data field names match xField/yField, otherwise the chart may not display
💡 Please provide feedback if you encounter issues, I will diagnose immediately

问题反馈关键词 → 立即切换场景1

Issue Feedback Keywords → Switch to Scenario 1 Immediately

"报错"/"error"/"不工作"/"失败"
"没显示"/"空白"/"不出来"
"数据不对"/"Y轴空"/"X轴乱"
"为什么"/"有问题"/"不对"
"帮我看看"/"检查"/"诊断"

"Error"/"error"/"not working"/"failed"
"Not displaying"/"blank"/"not showing up"
"Incorrect data"/"Empty Y-axis"/"Messy X-axis"
"Why"/"there's a problem"/"incorrect"
"Help me check"/"inspect"/"diagnose"

知识库查询指南

Knowledge Base Query Guide

配置项查询

Configuration Item Query

当需要查找配置项时，按以下顺序查询：

用户意图 → topkey/*.json → type-meta/*.json → type-details/*.md

查询流程：

意图识别：用户说"加个标签" → 查询
```
references/topkey/[图表类型].json
```
→ 找到
```
label
```
配置项
结构查询：需要 label 的属性 → 查询
```
references/type-meta/[图表类型].json
```
→ 找到
```
label
```
的类型定义

类型详情：

label

类型为

ILabelSpec

（isSimple: false）→ 查询

references/type-details/ILabelSpec-Type-Definition.md

常用配置项索引：
通用配置（标题、图例、tooltip等）→
references/topkey/all_common.json
图表专属配置 →
references/topkey/[图表类型].json

When you need to find configuration items, query in the following order:

User Intent → topkey/*.json → type-meta/*.json → type-details/*.md

Query Process：

Intent Recognition: User says "add a label" → Query
```
references/topkey/[chart-type].json
```
→ Find the
```
label
```
configuration item
Structure Query: Need attributes of label → Query
```
references/type-meta/[chart-type].json
```
→ Find the type definition of
```
label
```

Type Details:

label

type is

ILabelSpec

(isSimple: false) → Query

references/type-details/ILabelSpec-Type-Definition.md

Common Configuration Item Index：
General configuration (title, legend, tooltip, etc.) →
references/topkey/all_common.json
Chart-specific configuration →
references/topkey/[chart-type].json

类型定义查询

Type Definition Query

根据

type-meta

中的

isSimple

字段判断查询策略：

isSimple	类型示例	查询方式
`true`	`boolean` , `string`	直接使用 `references/type-meta` 中的 `type` 字段
`false`	`ILabelSpec` , `IData`	查询 `references/type-details/[类型名]-Type-Definition.md`
函数类型	回调函数	查询 `references/type-details/FunctionType-Type-Definition.md`

Determine the query strategy based on the

isSimple

field in

type-meta

isSimple	Type Example	Query Method
`true`	`boolean` , `string`	Directly use the `type` field in `references/type-meta`
`false`	`ILabelSpec` , `IData`	Query `references/type-details/[type-name]-Type-Definition.md`
Function Type	Callback function	Query `references/type-details/FunctionType-Type-Definition.md`

通用查询策略

General Query Strategy

查询优先级

Query Priority

```
in
```
type-meta
```
are configured
Clear Comments: Add comment explanations for key configuration items
Version Compatibility: Use APIs of VChart 2.0.0+
React Requirements: If users explicitly require React-VChart, prioritize using React code/templates (see React diagnosis template) and prompt for dependency installation

输出规范

Output Specifications

所有场景处理完成后，必须输出可直接运行的 HTML 文件，不得只返回 spec 片段。

After processing all scenarios, must output directly runnable HTML files, do not only return spec fragments.

模板选择与硬约束

Template Selection and Hard Constraints

场景	使用模板	强制要求
配置生成 / 视觉还原	`template/demo.html`	替换标题/描述占位；替换 `{{SPEC_CODE}}` 为完整 spec
问题诊断（纯 JS）	`template/diagnosis.html`	嵌入用户代码/问题点，并给出修复后 spec
问题诊断（React）	`template/diagnosis-react.html`	React 场景输出 React 诊断 HTML

输出校验清单（回答时提醒用户可直接保存为 .html 打开）：

包含对应模板的完整 HTML（含 CDN 引用），非截断/片段
替换
```
{{SPEC_CODE}}
```
为完整 spec（或修复后的 spec）
标题/描述占位已替换；如无描述填入简短用途
如需本地预览，建议
```
python3 -m http.server 8000
```

不合格示例（禁止）：

仅返回
```
const spec = {...}
```
或局部配置
省略 HTML 头/脚或 CDN 链接
未替换模板占位符

Scenario	Template Used	Mandatory Requirements
Configuration Generation / Visual Restoration	`template/demo.html`	Replace title/description placeholders; replace `{{SPEC_CODE}}` with complete spec
Problem Diagnosis (pure JS)	`template/diagnosis.html`	Embed user code/problem points and provide fixed spec
Problem Diagnosis (React)	`template/diagnosis-react.html`	Output React diagnosis HTML for React scenarios

Output Check List (remind users that they can directly save as .html to open):

Contains complete HTML of the corresponding template (including CDN references), not truncated/fragmented
Replaced
```
{{SPEC_CODE}}
```
with complete spec (or fixed spec)
Title/description placeholders have been replaced; fill in a short purpose if no description is available
For local preview, recommend
```
python3 -m http.server 8000
```

Unqualified Examples (Forbidden)：

Only return
```
const spec = {...}
```
or partial configuration
