Data

Start from distribution sample data

Templates load with grouped raw samples that ECharts transforms into quartile boxes automatically. Replace values per category in the dataset panel to match your experiment or survey groups.

Output

Export for lab reports and decks

Download high-resolution PNG for slides, vector SVG for design tools, or PDF for documents. Box colors, median lines, and axis labels carry through to every export format.

Box plot layouts

Start from a vertical group comparison or a horizontal layout for long category labels, then open any example in the editor.

  • Vertical group comparison box plot
    Compare medians and spread across experiment runs or product variants. Sample raw measurements transform into quartile boxes per category on the horizontal axis.
    Open vertical box plot
  • Horizontal box plot layout
    Flip the chart when category names are long or you need a sideways distribution view. Whiskers and median lines follow the same five-number summary rules.
    Open horizontal box plot

Popular use cases for box plots

Box plots summarize how values spread within groups. These are common workflows teams build in the editor and export for analysis decks.

  • Experiment and A/B test results
    Compare latency, conversion lift, or response times across variants when median and spread matter more than a single average bar.
  • Salary and compensation bands
    Show quartile ranges across roles or regions while keeping individual outliers visible beyond the whiskers.
  • Quality and manufacturing samples
    Track measurement distributions per batch or line to spot shifts in median or widening spread before defects spike.
  • Survey score distributions
    Summarize Likert or numeric ratings per segment when you need spread and median, not just mean totals.
  • Scientific replication studies
    Plot replicate measurements per condition, then export SVG for papers or PNG for conference slides.
  • Operations and SRE latency review
    Compare request-duration samples across services or regions to see whether tail latency diverges even when medians look similar.

Editor features for box plots

Distribution templates, whisker styling, and export options to move from grouped samples to a readable box-and-whisker chart quickly.

  • Box plot templates
    Jumpstart from vertical and horizontal distribution layouts with sample grouped data you can open in one click.
  • Quartile transform from samples
    Templates use ECharts dataset transforms so raw measurements per category become median lines and interquartile boxes automatically.
  • Whisker and outlier styling
    Control box borders, median emphasis, whisker length rules, and outlier dot display so extreme values stay visible.
  • Category axis labels
    Set axis titles and tick labels for experiment groups, regions, or product variants compared on the same chart.
  • Orientation options
    Switch between vertical and horizontal templates when long category names need more label space.
  • Export and share
    Save PNG, SVG, or PDF files for lab reports, analytics decks, and documentation workflows.

How to create a box and whisker plot online in 4 steps

Four steps to create a box and whisker plot: pick a template, add distribution data, customize, and export
  1. Open the box and whisker plot maker or pick a vertical or horizontal template below.
  2. Replace sample grouped values in the dataset panel with your measurements or five-number summaries.
  3. Customize box colors, median lines, whiskers, and outlier markers until the distribution comparison reads clearly.
  4. Export as PNG, SVG, or PDF and add the chart to your report, slide deck, or paper.

What is a box and whisker plot?

A box and whisker plot—also called a box plot, boxplot, box chart, or whisker diagram—summarizes a distribution with a median line, an interquartile box from the first to third quartile, whiskers that extend to typical min and max values, and optional outlier points beyond the whiskers.

Online box plot makers and generators let you compare several groups on one axis without calculating quartiles in a spreadsheet first. Templates can start from raw sample rows per category; the editor computes boxes and whiskers from those values.

Box graphs fit when spread and median matter across categories—experiment arms, salary bands, latency samples—not when you only need a single total per bar. Keep group counts and units consistent so viewers interpret whisker length correctly.

Box plot vs bar chart vs histogram

Use a box plot when you need median, quartiles, and outliers across groups—not just one total or average per category. Bar charts read faster for simple category sums at a single snapshot. Histograms show the shape of one distribution; box plots compare several distributions on shared axes.

Scatter plots plot individual x-y pairs; box plots aggregate many values per group into a compact summary. In BeCharts you can open a box plot template, style whiskers and median lines, and export PNG, SVG, or PDF when the comparison is ready.

Frequently asked questions

How do I create a box and whisker plot?
Click "Create your box plot" or open any template on this page. Replace grouped sample values in the dataset panel, adjust whiskers and colors, then export PNG, SVG, or PDF from the toolbar.
How do I make a box plot online?
Pick a vertical or horizontal template, edit distribution data per category in the dataset panel, style median lines and whiskers in the Series sidebar, and download your chart when the comparison is ready.
Is this a free box plot maker?
Yes. You can open box plot templates and the distribution editor without a credit card or account. Export options are available from the toolbar at no cost.
What is the difference between a box plot maker and a box plot calculator?
A calculator page usually returns quartile numbers only. BeCharts is a chart maker—it computes quartiles from your grouped data, draws the full whisker graphic, and lets you export PNG, SVG, or PDF.
Is this a box plot generator or a box plot creator?
Both terms describe the same workflow here. Open a template, enter or replace distribution data, customize styling, and export—the editor generates the whisker chart from your values.
Do I need pre-calculated quartiles?
Not always. Gallery templates include raw sample rows per category; ECharts transforms them into quartile boxes. You can also paste five-number summaries when your layout expects pre-aggregated values.
Can I import CSV into a box plot?
Box plots do not support CSV upload in the editor today. Replace sample values in the dataset panel or paste rows that match the template structure.
What is the difference between a box plot and a box-and-whisker chart?
They refer to the same chart type. "Box chart," "box graph," "boxplot," and "whisker diagram" are common synonyms; BeCharts uses one editor for all of them.
When should I use a bar chart instead of a box plot?
Use bars when you compare one value per category—totals, counts, or averages—and spread is not the story. Box plots fit when median, quartiles, and outliers across groups need to be visible together.
Can box plots show individual data points?
Some layouts emphasize outlier markers beyond the whiskers. For small samples, consider pairing a scatter plot with your box plot in a separate chart when every point should be visible.
How many groups can I compare?
Add categories in the dataset after opening a template. If labels crowd the axis, switch to the horizontal box plot template for more label space.
What file formats can I export?
PNG and SVG are supported for digital use, and PDF for documents. Exports reflect box, whisker, and axis styles from the editor.
