Purpose
AI Box Plot Generator is a free online statistical chart generation tool whose core purpose is to quickly create box plots (box-and-whisker plots) and provide statistical analysis with the help of AI. It is designed for users who need to visualize data distributions, compare multiple datasets, and detect outliers, without installing software or writing code.
Main Capabilities
- Chart types: supports box plots, violin plots, histograms, scatter plots, pie charts, Q-Q plots, stem-and-leaf plots, and outlier detection.
- Multi-dataset comparison: compare up to 10 datasets side by side, each with independent colors and labels, and supports notch display and jittered scatter overlay.
- Statistical computation: draws box plots based on the five-number summary (minimum, first quartile Q1, median, third quartile Q3, maximum). Quartiles use linear interpolation (Hyndman & Fan method 7), consistent with Python's NumPy and pandas. Outliers are determined using Tukey's fences: lower bound = Q1 − 1.5×IQR, upper bound = Q3 + 1.5×IQR. Notched box plots show the 95% confidence interval around the median (±1.58 × IQR / √n), which can be used for visual significance testing.
- Export: supports PNG, SVG, CSV, XLSX, HTML, and Markdown formats, with clean, watermark-free output that can be used directly for publication or presentation.
- AI analysis: click "AI Analysis" to open the full tool, chat with AI to get statistical insights, ask questions about the data, and generate custom visualizations.
- Privacy: all calculations run locally in the browser, and data never leaves the user's device.
How to Use
- Enter data: enter or paste numbers directly into the tool above, separated by commas, spaces, or line breaks.
- Add multiple datasets: click "+" to compare different groups side by side, with each group automatically assigned a color and label.
- Customize the chart: in the advanced panel, adjust outlier sensitivity, toggle jitter/mean/notch overlays, and choose colors.
- Export results: download PNG, SVG, CSV, XLSX, HTML, or Markdown with one click.
- Get AI analysis: click "AI Analysis →" to open the full tool with AI statistical insights.
Use Cases
- Education: students complete homework, statistics course assignments, and classroom presentations without installing software, using only a browser.
- Data analysis: in exploratory dataQuickly visualize distributions during analysis, compare multiple datasets side by side, and export publication-ready SVG charts.
- Academic research: generate clean, watermark-free box plots for papers and presentations, and export high-resolution PNG or editable SVG for LaTeX and Word documents.
- Business: track KPIs, compare team performance, visualize survey results, and use them for report sharing.
