### Technical Document Extraction: Stacked Bar Chart Analysis
#### 1. Image Overview
This image is a stacked bar chart representing the distribution of four categories across four different scopes (Line, Function, File, and Overall). The Y-axis represents "Percentage" ranging from 0 to 100.
#### 2. Component Isolation
* **Header/Title:** None present.
* **Y-Axis:** Labeled "Percentage" with markers at 0, 20, 40, 60, 80, and 100.
* **X-Axis:** Contains four categorical labels: "Line", "Function", "File", and "Overall".
* **Legend:** Located at the bottom left. It defines four color-coded categories:
* **Light Blue:** None
* **Purple:** Stack trace
* **Green:** Natural language
* **Red:** Keywords
#### 3. Data Table Reconstruction
The following table represents the precise numerical data extracted from the labels within each segment of the stacked bars.
| Scope | None (Blue) | Stack trace (Purple) | Natural language (Green) | Keywords (Red) | Total |
| :--- | :--- | :--- | :--- | :--- | :--- |
| **Line** | 90.3% | 3.0% | 6.7% | 0.0%* | 100% |
| **Function** | 68.0% | 6.7% | 13.7% | 11.7% | 100.1%** |
| **File** | 50.0% | 13.7% | 15.3% | 21.0% | 100% |
| **Overall** | 39.3% | 13.7% | 24.7% | 22.3% | 100% |
*\*Note: The "Keywords" segment is not visible/labeled for the "Line" category.*
*\*\*Note: Sum exceeds 100% slightly due to rounding in the source data.*
#### 4. Trend Verification and Analysis
* **"None" (Light Blue):** This is the base segment of every bar. It shows a significant **downward trend** as the scope broadens, starting at a dominant 90.3% at the "Line" level and dropping to 39.3% at the "Overall" level.
* **"Stack trace" (Purple):** This segment shows an **upward trend** in prevalence as the scope increases, growing from 3.0% (Line) to 13.7% (File and Overall).
* **"Natural language" (Green):** This segment shows a consistent **upward trend**, more than tripling in representation from 6.7% (Line) to 24.7% (Overall).
* **"Keywords" (Red):** This is the top-most segment. It is absent at the "Line" level and shows a **sharp upward trend** starting from the "Function" level (11.7%) and peaking at the "Overall" level (22.3%).
#### 5. Summary of Findings
The data indicates that as the granularity of the scope moves from specific ("Line") to broad ("Overall"), the "None" category decreases drastically. Conversely, the presence of "Stack trace", "Natural language", and "Keywords" all increase, with "Natural language" and "Keywords" becoming major components at the "Overall" level.
