The Briqlab Violin Plot is a free Power BI custom visual for data analysts and advanced BI developers who need to go beyond summary statistics and communicate the full shape of a distribution. Where a box plot shows median, quartiles, and outliers, and a histogram shows frequency counts in fixed bins, the violin plot combines both — the interquartile range sits inside the violin body while the symmetric width at every point encodes probability density.
• Combined violin and box plot — probability density shape and interquartile range markers rendered in a single visual
• Symmetric KDE encoding — kernel density estimation calculated automatically from your raw data without scripting
• Median and quartile markers — overlaid inside the violin body for dual-audience readability
• Skewness detection annotations — directional indicators flag significantly skewed distributions automatically
• Multi-category comparison — stack multiple violins side by side to compare distributional shape across groups
• Automated colour-coding by category with a configurable palette
• Cross-filter and cross-highlight interaction with other report visuals
• Dark and light theme compatible with no extra setup
• Salary and compensation analysis — distributional shape across departments revealing outliers that means conceal
• Manufacturing quality control — measurement distribution per shift or machine for calibration and process monitoring
• Model validation — predicted vs actual value distribution comparison for bias and error pattern detection
• Customer behaviour analysis — purchase value or session duration distribution across customer segments
• Clinical and research reporting — outcome measure distributions across treatment or study groups
