Create a Box Plot with Data Points online with InstaNANO
The InstaNANO Graph Plotter can create a box plot with data points directly in your browser. The interactive graph above is already initialized with example data. Replace those values with your own table, assign the supported column roles, adjust the graph settings, and inspect the result on the same page.
A box plot with data points combines quartile summary with the individual observations. Use it when the compact summary is useful but hiding the sample size or clustering would be misleading.
Required data columns and series controls
| Column role | Supported layout | How InstaNANO uses it |
|---|---|---|
| Y-axis | One or more numeric sample columns | Each enabled column is treated as one distribution or probability sample. |
Each Y-axis Color and Name row defines one displayed sample. There is no X-axis input: the graph derives the horizontal position, probability, or category position from the values.
How to make this graph
- Start with the working example. Review the graph and table loaded above so the relationship between the columns and plotted marks is visible before you replace the values.
- Enter or paste your data. Keep the columns in the supported order shown in the table below the graph. Use the Axis row to assign each column’s role.
- Name and distinguish the series. Where the current graph supports them, use the Name row for the displayed series label and the Color row for its color.
- Check the scientific context. Add meaningful axis titles and units, review scale choices, and confirm that row order, missing values, uncertainty columns, or normalization match the intended interpretation.
- Refine and export. Use the available graph controls described below. When the figure is ready, sign in to export a PNG with Download Graph or preserve an editable

What the loaded example demonstrates
The starter table contains two small hardness samples, “Alloy A” and “Alloy B”. It demonstrates separate numeric value columns and should not be used to infer a population distribution from the example alone.
What InstaNANO calculates and renders
The renderer calculates the same quartile and 1.5×IQR whisker summary as the box plot, then adds deterministically jittered point symbols for every finite sample value.
The Y-axis Color and Name rows identify each sample; symbol size controls affect the shown observations.
Scientific instruments and research data suited to this graph
Use it for small to moderate experimental datasets where readers need to inspect both central tendency and the distribution of individual measurements.
Broad instrument and data coverage
- Microscopy-derived populations: Particle, grain, pore, fiber, cell, droplet, or defect sizes; aspect ratios; circularity; orientation; spacing; and other numerical features extracted from SEM, TEM, STEM, AFM, optical, or confocal images.
- Spectroscopy and diffraction features: Peak positions, widths, areas, intensity ratios, chemical shifts, binding energies, lifetimes, and other values extracted from repeated XRD, Raman, FTIR, UV–visible, PL, XPS, NMR, EELS, or EDS measurements.
- Surface, dimensional, and thermal measurements: Roughness, height, thickness, dimensional deviation, transition temperature, mass loss, heat-flow metrics, and local temperature values collected across samples or locations.
- Mechanical, electrical, electrochemical, and transport properties: Hardness, strength, modulus, conductivity, resistance, capacity, efficiency, diffusivity, permeability, and replicate device or specimen measurements.
- Reliability, process, biological, and computational samples: Failure times, cycle life, reaction yields, sensor readings, assay values, population measurements, Monte Carlo outputs, residuals, and parameter ensembles.
Representative questions for this exact graph
- Small replicate datasets where every measurement and the quartile summary should be visible.
- Material-property groups inspected for clustering, sample size, and potential outliers.
- Screening results where the raw observations prevent an over-compressed summary.
This coverage is not limited to the instruments named above. InstaNANO can plot other experimental, microscopy-derived, computational, simulation, and processed research data when the required column roles are present and this graph’s encoding is scientifically appropriate.
Data checks before interpretation
- Retain the sample size and units for every numeric column.
- Inspect missing, censored, rounded, or excluded observations before interpreting a derived distribution summary.
Frequently asked questions about Box Plot with Data Points
Does horizontal point jitter represent another measured variable?
Point jitter is visual separation, not an additional variable. The box remains a descriptive summary, and apparent outliers should be checked against experimental quality rather than removed automatically.
Can I plot data from instruments or research workflows not listed here?
Yes. The instrument and dataset examples on this page are representative rather than a fixed compatibility list. InstaNANO can create a box plot with data points from other experimental, computational, simulation, and processed research data when the table follows these roles: Y-axis (one or more numeric sample columns). Microscopy use refers to numeric profiles, coordinates, dimensions, counts, intensities, distributions, or map values extracted from images; the graph does not convert a raw micrograph into numerical data.
Can I use this box plot with data points in a publication, thesis, report, poster, or presentation?
Yes, after scientific and visual review. InstaNANO can be used to prepare a box plot with data points for a journal manuscript, thesis or dissertation, technical report, poster, conference slide, classroom presentation, or other formal scientific communication. After sign-in, Download Graph exports a PNG, defaults to 600 dpi, and offers a transparent-background option. For this graph, report sample size, units, exclusions, censoring, and the descriptive or diagnostic calculation represented by the graph. Also check final dimensions, font size, line and symbol weight, color accessibility, caption content, and the destination’s required file format. The current export is PNG, so a journal that requires TIFF, EPS, PDF, SVG, or another format needs a journal-specific workflow. InstaNANO supports figure preparation, but it cannot guarantee that a journal, conference, institution, or publisher will accept a figure.
