# Technical Document Extraction: Line Chart Analysis
## Axes and Labels
- **X-axis**: Labeled "k" with discrete values at 1, 2, 3 (integer increments).
- **Y-axis**: Labeled "Pass@k (%)" with a range from 5.0% to 17.5%, marked in 2.5% increments (5.0, 7.5, 10.0, 12.5, 15.0, 17.5).
## Legend
- **Position**: Bottom-right corner of the chart.
- **Entries**:
- **RL**: Red line with square markers.
- **SFT**: Orange line with circular markers.
- **MT**: Purple line with circular markers.
- **Base**: Blue line with circular markers.
## Data Series and Trends
1. **RL (Red)**:
- **Trend**: Steady upward slope.
- **Data Points**:
- k=1: ~11.5%
- k=2: ~13.0%
- k=3: ~14.5%
2. **SFT (Orange)**:
- **Trend**: Consistent upward trajectory.
- **Data Points**:
- k=1: ~12.0%
- k=2: ~13.5%
- k=3: ~15.5%
3. **MT (Purple)**:
- **Trend**: Sharpest upward slope.
- **Data Points**:
- k=1: ~12.5%
- k=2: ~15.0%
- k=3: ~16.5%
4. **Base (Blue)**:
- **Trend**: Moderate upward slope with plateauing.
- **Data Points**:
- k=1: ~8.5%
- k=2: ~12.0%
- k=3: ~12.5%
## Key Observations
- **Performance Comparison**:
- MT outperforms all methods at k=3 (~16.5%).
- Base starts lowest at k=1 (~8.5%) but closes the gap by k=3 (~12.5%).
- SFT and RL show similar growth rates, with SFT slightly ahead at k=3 (~15.5% vs. RL's ~14.5%).
## Spatial Grounding
- **Legend Placement**: Bottom-right quadrant, outside the main plot area.
- **Data Point Alignment**: All markers (squares/circles) align vertically with their respective k-values on the x-axis.
## Structural Notes
- **Chart Type**: Line chart with discrete x-axis values (k=1, 2, 3).
- **Gridlines**: Dashed gray lines at y-axis increments (5.0, 7.5, 10.0, 12.5, 15.0, 17.5).
- **No Additional Text**: No embedded text blocks or annotations beyond axis labels and legend.
## Data Table Reconstruction
| k | RL (%) | SFT (%) | MT (%) | Base (%) |
|----|--------|---------|--------|----------|
| 1 | 11.5 | 12.0 | 12.5 | 8.5 |
| 2 | 13.0 | 13.5 | 15.0 | 12.0 |
| 3 | 14.5 | 15.5 | 16.5 | 12.5 |
## Language Declaration
- **Primary Language**: English (all labels, axis titles, and legend entries are in English).
