# Example Analysis Scripts
This directory contains working example analysis scripts that demonstrate how to use the sales analysis template framework.
## Available Examples
### 1. Annual Revenue Trend (`examples/annual_revenue_trend.py`)
**Purpose:** Simple annual revenue analysis with LTM support
**What it demonstrates:**
- Loading data using `data_loader`
- Calculating annual metrics with LTM
- Creating a revenue trend chart
- Following template best practices
**Usage:**
```bash
python examples/annual_revenue_trend.py
```
**Output:**
- Chart: `charts/annual_revenue_trend.png`
- Console output with annual revenue summary
---
### 2. Customer Segmentation (`examples/customer_segmentation.py`)
**Purpose:** Customer segmentation using RFM (Recency, Frequency, Monetary) methodology
**What it demonstrates:**
- Customer-level aggregation
- RFM scoring and segmentation
- Segment analysis and visualization
- Multiple chart generation
**Usage:**
```bash
python examples/customer_segmentation.py
```
**Output:**
- Chart: `charts/customer_segmentation.png`
- Console output with segment summary
**Segments:**
- **Champions:** High recency, frequency, and monetary value
- **Loyal Customers:** Regular customers with good value
- **At Risk:** Recent but declining frequency
- **Hibernating:** Low recency, may need reactivation
- **Potential Loyalists:** Good recency and frequency, lower value
- **Need Attention:** Mixed signals, need engagement
---
### 3. Product Performance (`examples/product_performance.py`)
**Purpose:** Product mix and performance analysis
**What it demonstrates:**
- Product-level aggregation
- Product performance metrics
- Top products identification
- Product mix visualization
**Usage:**
```bash
python examples/product_performance.py
```
**Output:**
- Chart: `charts/product_performance.png`
- Console output with top products summary

## How to Use Examples
### Step 1: Configure Template
Before running examples, ensure your template is configured:
```bash
python setup_wizard.py
```
Or manually update `config.py` with your data file and column mappings.
### Step 2: Prepare Data
Place your sales data CSV file in the template directory, or update `DATA_DIR` in `config.py`.
Alternatively, generate sample data for testing:
```bash
python generate_sample_data.py
```
### Step 3: Run Example
```bash
python examples/annual_revenue_trend.py
```
### Step 4: Customize
Copy an example script and modify it for your needs:
```bash
cp examples/annual_revenue_trend.py my_analysis.py
# Edit my_analysis.py
python my_analysis.py
```

## Example Patterns
### Pattern 1: Simple Annual Analysis
```python
from data_loader import load_sales_data
from analysis_utils import calculate_annual_metrics, get_ltm_period_config
from config import REVENUE_COLUMN
df = load_sales_data(get_data_path())
ltm_start, ltm_end = get_ltm_period_config()
def calculate_metrics(year_data):
return {'Revenue': year_data[REVENUE_COLUMN].sum()}
annual_df = calculate_annual_metrics(df, calculate_metrics, ltm_start, ltm_end)
```
### Pattern 2: Customer-Level Analysis
```python
from config import CUSTOMER_COLUMN, REVENUE_COLUMN
customer_metrics = df.groupby(CUSTOMER_COLUMN).agg({
REVENUE_COLUMN: 'sum',
DATE_COLUMN: 'count'
}).reset_index()
```
### Pattern 3: Product-Level Analysis
```python
from config import ITEM_COLUMN, REVENUE_COLUMN
product_metrics = df.groupby(ITEM_COLUMN)[REVENUE_COLUMN].sum().sort_values(ascending=False)
top_10 = product_metrics.head(10)
```

## Learning Path
1. **Start with:** `annual_revenue_trend.py` - Simplest example
2. **Then try:** `product_performance.py` - More complex aggregation
3. **Advanced:** `customer_segmentation.py` - Multi-step analysis with custom logic
---
## Troubleshooting
**"Module not found" errors:**
- Ensure you're running from the template root directory
- Check that all template files are present
**"Data file not found" errors:**
- Run `setup_wizard.py` to configure data file path
- Or update `DATA_FILE` in `config.py`
**"Column not found" errors:**
- Update column mappings in `config.py`
- Run `python config_validator.py` to check configuration

## Next Steps
After running examples:
1. Review the generated charts
2. Examine the code to understand patterns
3. Copy an example and customize for your analysis
4. Check `.cursor/rules/analysis_patterns.md` for more patterns
5. Read `.cursor/rules/advanced_analysis_patterns.md` for advanced techniques
6. Use Cursor AI with prompts from `ai_assistant_guide.md`
7. Read `README.md` for comprehensive documentation
