# Technical Document Extraction: Bar Chart Analysis
## Overview
The image contains **four grouped bar charts** comparing performance metrics across five evaluation categories: **Few-shot**, **CoT**, **Multi-turn**, **RAG**, and **MACOG**. Each chart represents a distinct evaluation metric, with scores plotted on a y-axis labeled "Score". The x-axis consistently lists the five categories across all charts. Colors are standardized across charts to represent categories.
---
### Chart 1: BLEU
- **Y-axis range**: 0–10
- **Key trends**:
- **MACOG** achieves the highest score (~10).
- **RAG** follows closely (~9.5).
- **Multi-turn** (~8.5) and **Few-shot** (~5) show moderate performance.
- **CoT** has the lowest score (~4.5).
---
### Chart 2: CodeBERTScore
- **Y-axis range**: 0–70
- **Key trends**:
- **MACOG** leads with ~70.
- **RAG** (~68) and **Multi-turn** (~65) are near-peak.
- **Few-shot** (~65) and **CoT** (~60) show lower but competitive scores.
---
### Chart 3: LLM-judge
- **Y-axis range**: 0–80
- **Key trends**:
- **Few-shot** achieves the highest score (~60).
- **MACOG** (~55) and **RAG** (~50) follow.
- **Multi-turn** (~55) and **CoT** (~50) are mid-range.
---
### Chart 4: IaC-Eval
- **Y-axis range**: 0–60
- **Key trends**:
- **MACOG** dominates with ~60.
- **RAG** (~45) and **Multi-turn** (~35) show moderate performance.
- **Few-shot** (~12) and **CoT** (~10) are significantly lower.
---
### Color Legend Consistency
- **Few-shot**: Blue
- **CoT**: Purple
- **Multi-turn**: Green
- **RAG**: Orange
- **MACOG**: Red
Colors are uniformly applied across all charts to maintain category consistency.

### Summary of Highest Scores by Category
| Category | Metric | Highest Score |
|------------|-----------------|---------------|
| Few-shot | LLM-judge | ~60 |
| CoT | CodeBERTScore | ~60 |
| Multi-turn | CodeBERTScore | ~65 |
| RAG | BLEU | ~9.5 |
| MACOG | All metrics | ~70 (CodeBERTScore), ~60 (IaC-Eval), ~10 (BLEU) |
---
### Observations
1. **MACOG** consistently outperforms other categories in **BLEU**, **CodeBERTScore**, and **IaC-Eval**.
2. **Few-shot** excels in **LLM-judge** but underperforms in other metrics.
3. **CoT** shows the lowest scores across all metrics except CodeBERTScore.
4. **RAG** performs well in **BLEU** and **CodeBERTScore** but lags in **IaC-Eval**.
