# Technical Document Extraction: Bar Chart Analysis
## Chart Title
**(b) Samples failed at each step**
## Legend
- **CoT**: Orange bars
- **ToT (b=5)**: Green bars
## Axis Labels
- **X-Axis**: Steps (1, 2, 3, 4, Correct)
- **Y-Axis**: Decimal scale (0.0 to 0.6, increments of 0.2)
## Key Data Points
1. **Step 1**
- CoT: ~0.6 (highest failure rate)
- ToT (b=5): ~0.1
2. **Step 2**
- CoT: ~0.3
- ToT (b=5): ~0.05
3. **Step 3**
- CoT: ~0.01 (near-zero failure)
- ToT (b=5): ~0.05
4. **Step 4**
- CoT: ~0.01 (near-zero failure)
- ToT (b=5): ~0.05
5. **Correct**
- CoT: ~0.03
- ToT (b=5): ~0.7 (highest failure rate in "Correct" category)
## Observations
- **CoT** shows significant failure rates in early steps (1 and 2), with near-zero failures in later steps (3, 4, Correct).
- **ToT (b=5)** exhibits minimal failures in steps 1–4 but a sharp increase in the "Correct" category (~0.7).
- The "Correct" category for ToT (b=5) has the highest failure rate overall, exceeding CoT's peak at Step 1.
## Structural Notes
- Bars are grouped by step, with CoT (orange) and ToT (green) differentiated by color.
- No data table present; values are inferred from bar heights relative to the y-axis scale.
