- Added pipeline_converging_triangle.py for streamlined execution of detection, reporting, and chart generation. - Introduced triangle_config.py for centralized parameter management across scripts. - Updated plot_converging_triangles.py to utilize parameters from the new config file. - Revised report_converging_triangles.py to reflect dynamic detection window based on configuration. - Enhanced existing scripts for improved error handling and output consistency. - Added new documentation files for usage instructions and parameter configurations.

# 枢轴点绘图问题记录
|

> 主题：收敛三角形图表中枢轴点位置异常与修复
|
||
|
||
## 背景现象
|
||
|
||
在 `outputs/converging_triangles/charts` 生成的图表中，标注的枢轴点（用于连线的关键点）出现**挤在一起**、位置不正确的问题。
|
||
|
||
## 根因分析
|
||
|
||
`fit_pivot_line()` 返回的 `selected_ph / selected_pl` 是**枢轴点数组中的索引**，而非检测窗口的真实索引。
|
||
绘图时直接用 `selected_ph` 作为 `high_win`/`low_win` 的索引，导致标注位置偏移到窗口开头。
|
||
|
||
问题代码路径：
|
||
- `scripts/plot_converging_triangles.py`
|
||
- 相关逻辑：`selected_ph` / `selected_pl` 与 `ph_idx` / `pl_idx` 的索引映射
|
||
|
||
## 修复方式
|
||
|
||
将枢轴点索引转换为真实位置：
|
||
|
||
```python
|
||
selected_ph_pos = ph_idx[selected_ph]
|
||
selected_pl_pos = pl_idx[selected_pl]
|
||
```
|
||
|
||
绘图时使用真实位置：
|
||
|
||
```python
|
||
ax1.scatter(selected_ph_display, high_win[selected_ph_pos], ...)
|
||
ax1.scatter(selected_pl_display, low_win[selected_pl_pos], ...)
|
||
```
|
||
|
||
## 视觉优化
|
||
|
||
将枢轴点标注样式改为**空心圆圈**，避免遮挡价格曲线：
|
||
|
||
```python
|
||
marker='o', facecolors='none', edgecolors='red/green', linewidths=1.5
|
||
```
|
||
|
||
## 更新文件
|
||
|
||
- `scripts/plot_converging_triangles.py`
|
||
- 修复枢轴点索引映射
|
||
- 空心圆圈样式
|
||
|
||
## 验证步骤
|
||
|
||
重新生成图表：
|
||
|
||
```bash
|
||
python scripts/plot_converging_triangles.py
|
||
```
|
||
|
||
验证要点：
|
||
- 红/绿空心圆应落在真实高点/低点位置
|
||
- 不再出现“所有枢轴点挤在一起”的情况
|
||
|

|

|

如需进一步增强可视化，可新增“显示所有枢轴点”的开关，用于诊断与验证。
