[box-grouped] Grouped Box Plot

[MarkusNeusinger]

Plot Request

Multiple box plots grouped by category.

Use Cases

• Comparing distributions across groups
• A/B testing with multiple metrics
• Multi-factor experiments

Expected Features

• Side-by-side boxes per group
• Different colors for subcategories
• Clear legend

[claude]

✅ Spec ID: box-grouped

Rationale: This is a grouped box plot showing side-by-side boxes per group—distinct from box-basic which shows single boxes per category. The grouped variant enables comparison of multiple subcategories (e.g., A/B groups) within each main category.

Add label approved to begin generation.

box-grouped: Grouped Box Plot

Description

A grouped box plot displays multiple box plots side-by-side within each category, enabling comparison of distributions across subgroups. Each group contains boxes representing different subcategories or conditions, making it ideal for multi-factor comparisons and A/B testing scenarios with multiple metrics.

Applications

• Comparing treatment effects across different patient demographics in clinical trials
• A/B testing with multiple metrics (conversion rate, time on site) across user segments
• Analyzing performance distributions by department and experience level
• Comparing experimental results across multiple factors in research studies

Data

• category (string) - main group labels (x-axis categories)
• subcategory (string) - subgroup identifiers for side-by-side boxes
• value (numeric) - numerical values to plot
• Size: 20-200 points per subcategory, 2-6 categories, 2-4 subcategories

Notes

• Display boxes side-by-side within each category with distinct colors
• Include a clear legend identifying each subcategory
• Maintain consistent box widths across all groups
• Show median line, quartile box, whiskers at 1.5*IQR, and outliers
