Prerequisites

Install Python dependencies:

bash
pip install pandas matplotlib scipy openpyxl

Usage

Basic Chart Generation

bash
python3 ./scripts/growth_chart.py "Child Name" "DD.MM.YYYY" --sex F --type all

Arguments:

  • name: Child's name (used in chart title)
  • birthdate: Date of birth in DD.MM.YYYY format
  • --sex / -s: F (female) or M (male) — default: F
  • --type / -t: height, weight, bmi, or all — default: all
  • --data / -d: JSON file with measurement data
  • --output / -o: Output directory for charts

With Measurement Data

Create a JSON file with height/weight measurements (heights in meters, weights in kg):

json
{
  "heights": [ ["2024-01-15T10:00:00", 1.05] ],
  "weights": [ ["2024-01-15T10:00:00", 17.5] ]
}
bash
python3 ./scripts/growth_chart.py "Emma" "06.07.2016" --sex F --data emma_data.json --type all

Integration with Withings

Combine with withings-family skill to fetch weight data automatically:

bash
# Get Withings weight data (assuming withings-family skill is installed)
python3 ../withings-family/scripts/withings.py emma body > /tmp/withings.json

# Parse and generate charts
# (The growth chart script handles Withings JSON format if implemented, otherwise transform it)

Output

Charts are saved as PNG files in ~/clawd/who-growth-charts/ by default (or specified output directory). Data cache and assets are stored in ~/clawd/who-growth-charts/cache/.
