# Python Charts
|
|
|
|
This initial chart is a self-contained toolkit that:
|
|
|
|
* Fetches U.S. unemployment rate (UNRATE) and WTI crude oil price (DCOILWTICO) from FRED
|
|
* Stores the series in a local SQLite database (`data/fred.db`)
|
|
* Produces a dual-axis plot of unemployment vs. lagged oil price, with customizable lag, date range, and styling
|
|

|
## 🚀 Quickstart
|
|
|
|
```bash
|
|
# Clone the repo
|
|
git clone https://github.com/your-org/python_charts.git
|
|
cd python_charts
|
|
|
|
# One-command: install deps, download data, and plot
|
|
./startup.sh --offset 12 --end 2025-05-31 --extend-years 5
|
|
````
|
|
|
|
This will:
|
|
|
|
1. Upgrade `pip` & `setuptools` globally
|
|
2. Install required packages from `requirements.txt` via
|
|
|
|
```bash
|
|
pip install --upgrade -r requirements.txt
|
|
```
|
|
3. Download UNRATE & DCOILWTICO into `data/fred.db` if missing
|
|
4. Generate the chart with a 12-month oil lead, extending the x-axis by 5 years

## ⚙️ Usage
|
|
|
|
### Refresh FRED data
|
|
|
|
```bash
|
|
./startup.sh python scripts/refresh_data.py --series UNRATE CPIAUCSL --start 1960-01-01
|
|
```
|
|
|
|
Downloads UNRATE and WTI series (from 1948 to today) into `data/fred.db`.
|
|
|
|
#### `refresh_data.py` options
|
|
|
|
| Option | Description |
|
|
| ---------- | ----------------------------------- |
|
|
| `--series` | One or more FRED series names |
|
|
| `--start` | Start date in `YYYY-MM-DD` format |
|
|
| `--end` | End date in `YYYY-MM-DD` format |
|
|
|
|
To add new data and plot it later:
|
|
|
|
1. Download series:
|
|
|
|
```bash
|
|
./startup.sh python scripts/refresh_data.py --series <names>
|
|
```
|
|
|
|
2. Generate a chart with those series:
|
|
|
|
```bash
|
|
./startup.sh python scripts/custom_chart.py --series <names>
|
|
```
|
|
|
|
### Generate the chart
|
|
|
|
```bash
|
|
# Default 18-month lag
|
|
./startup.sh
|
|
|
|
# Custom lag, date range, and extension
|
|
./startup.sh --offset 6 --start 1980-01-01 --end 2025-05-31 --extend-years 2
|
|
```
|
|
|
|
The plotting script validates that both series contain data for the
|
|
requested period before rendering the chart.
|
|
|
|
| Option | Description |
|
|
| ---------------- | ----------------------------------------------- |
|
|
| `--offset` | Lag in months (pos = oil leads; neg = oil lags) |
|
|
| `--start` | Start date (YYYY-MM-DD) |
|
|
| `--end` | End date (YYYY-MM-DD) |
|
|
| `--extend-years` | Years to extend the x-axis beyond the end date |
|
|
| `--output` | Save the figure to this path before showing it |
|
|
|
|
## Custom Charts
|
|
|
|
Plot any combination of FRED series stored in `data/fred.db` using
|
|
`scripts/custom_chart.py`.
|
|
|
|
```bash
|
|
# Example: unemployment and oil
|
|
./startup.sh python scripts/custom_chart.py \
|
|
--series UNRATE DCOILWTICO --start 2000-01-01 --end 2020-12-31
|
|
```
|
|
|
|
The same invocation is available via Make:
|
|
|
|
```bash
|
|
make plot-custom ARGS="--series UNRATE DCOILWTICO --start 2000-01-01 --end 2020-12-31"
|
|
```

## 📝 Details
|
|
|
|
* **Data storage**: `data/fred.db` (SQLite) contains one table per series (e.g., `UNRATE`, `DCOILWTICO`).
|
|
* **Plot styling**:
|
|
|
|
* Left y-axis: unemployment rate (%) from 3 to 15%, ticks every 2%.
|
|
* Right y-axis: log scale oil price (USD), doubling ticks from \$3 upward.
|
|
* X-axis: major tick every 5 years, minor tick every year.
