How the Box & Whisker Plot Maker Works
Paste your numbers or load a CSV. For each series we compute the five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. Whiskers extend to the last points within 1.5×IQR (IQR = Q3 − Q1). Data beyond whiskers are plotted as outliers. All styling changes apply in real-time and the chart is fully responsive. KNVG3351

Frequently Asked Questions
How to generate a box and whisker plot?
Enter or paste your dataset(s). The tool computes the five-number summary (minimum, first quartile Q1, median, third quartile Q3, maximum). Whiskers extend to the last data points within 1.5×IQR (IQR = Q3 − Q1) and outliers are marked beyond that. Labels and colors update live; then export as PNG or SVG.
What is 75% of a boxplot?
The 75th percentile is the third quartile (Q3). In the plot, Q3 is the right edge of the box in a horizontal layout (or the top edge in a vertical layout).
What is a box and whisker plot maker?
It’s a tool that transforms raw numbers into a box-and-whisker chart, summarizing a distribution with its median, quartiles, whiskers, and outliers. This page renders it instantly as you type and lets you customize styling and labels.
What are the 5 main points of a box and whisker plot?
The five-number summary: Minimum, Q1 (25th percentile), Median (50th), Q3 (75th), and Maximum. These define the box (Q1–Q3) and the center line (median); whiskers typically extend to the most extreme non-outlier values.
