📘 rr2graph — Visualize Blood Pressure, Pulse, and Weight Data

rr2graph is a lightweight command-line tool for processing and visualizing blood pressure, pulse, and weight data stored in Excel files.
It generates monthly plots (box-swarm, scatter, histogram, violin) and exports them automatically as PNG, PDF, and SVG.

📤 Example Output

Example visualization using scatter and box-swarm plots:

Format: A4 Landscape (11.69 × 8.27 inch)

The CLI prints all generated files:

Heart rows read: 81
Weight rows read: 49
→ Excel file: rr_data.xlsx
→ Months: 3
→ Output folder: plots/
Generating histogram plots…
Generated histogram plots stored at:
– plots/png/(2026-02__2026-04 3 months) per month data and histogram.png
– plots/pdf/(2026-02__2026-04 3 months) per month data and histogram.pdf
– plots/svg/(2026-02__2026-04 3 months) per month data and histogram.svg

1. Ensure you are in the project root

   ~/your/project/directory/

2. Install in editable mode using Pipenv

   pipenv install -e .

   This installs:

   • the rr2graph package (editable mode)
   • all dependencies defined in pyproject.toml

3. Optional: Development dependencies

   pipenv install -r requirements_dev.txt

🧰 CLI Usage

After installation, the command rr2graph becomes available.

Show help:

rr2graph --help

usage: rr2graph [-h] [-e EXCEL] [-n NUM_OF_MONTHS] [-o OUTPUT] [-c CONFIG] [-v] [-g] [-i]

Reads Excel data and generates plots.

options:
  -h, --help            Show help and exit
  -e, --excel EXCEL     Path to Excel file (default: rr_data.xlsx)
  -n, --num_of_months NUM_OF_MONTHS
                        Number of months 1–6 (default: 3)
  -o, --output OUTPUT   Output folder for generated plots (default: plots/)
  -c, --config CONFIG   Optional YAML configuration file
  -v, --version         Show program version and exit
  -g, --generate-test-data
                        Generate test_rr_data.xlsx and exit
  -i, --info            Show system and configuration information

🧪 Generate Test Data

rr2graph -g

Creates:

test_rr_data.xlsx

with realistic blood pressure, pulse, and weight data.

🛠 Troubleshooting

❌ UnicodeDecodeError in YAML

You likely passed an Excel file as --config.

Correct:

rr2graph -c config.yaml

Incorrect:

rr2graph -c test_rr_data.xlsx

❌ CLI command not found

Reinstall:

pipenv install -e .
