Publication-ready graphs from your lab data. No coding required.

Drop in a CSV or Excel file and get a journal-style figure in seconds. Click anything on the chart — an axis, a label, the legend — and edit it right there: error bars, log scales, Greek symbols, exact tick spacing. Then export a high-resolution PNG for your paper, poster, or lab report.

figgy studio — Raman spectra chart with inspector

sample data: Raman spectra, D. Wales · Imperial College London · doi:10.14469/hpc/7135 (CC0)

Made for measurement data — and the people who collect it

If you've ever fought a spreadsheet's chart wizard the night before a deadline, this is for you. Defaults that look like a journal figure; every detail still yours to change.

▤

Drop a file — it's a project

Drag in a CSV or an Excel workbook and it's imported on the spot — every sheet, with X, Y and ±error columns guessed for you. Fix a value in the data table and the chart follows instantly.

◫

Figures that match — every time

Save your styling as a preset and apply it to the next dataset in one click, so every figure in your paper looks like it came from the same hand. Fixed aspect ratios keep every export the same shape.

◇

Speaks science

Error bars (X, Y, or both), logarithmic axes, scientific notation and 10ⁿ tick labels, Greek letters, subscripts and superscripts — ΔG‡, x₀, cm⁻¹ — anywhere text appears.

➤

Click the thing you want to change

Click an axis to set its range. Click a label to restyle it. Drag the title or legend where you want it. No hunting through menus to find which setting controls which part of the figure.

⚡

Built on a GPU renderer

Charts are drawn by your graphics card, so zooming and panning stay responsive on big traces — the kind of file a plate reader or an oscilloscope hands you before your first coffee.

Export for print or screen

High-resolution PNG at 1–4× — sharp enough for print — or copy the figure straight to the clipboard and paste it into your slides. Use any font your journal asks for.

From data file to figure in three steps

No tutorial needed — if you can use a spreadsheet, you already know how.

1 · Drop your data

Drag a CSV or Excel file onto the page — a workbook brings all its sheets along. figgy spots your X, Y and error columns automatically, and you can remap them anytime.

.csv · .xlsx · copy & paste

2 · Click to style

The first plot already looks like a journal figure. Click any part of it — axes, ticks, legend, title — to adjust exactly that. Like the result? Save it as a preset for your next dataset.

log scale · error bars · Δ α β x₀ 10ⁿ

3 · Export

Download a high-resolution PNG sized for your paper, poster, or thesis — or copy it to the clipboard and paste into your slides. The proportions stay locked, so figures match across the whole manuscript.

↳ Curious what's underneath? It's open source — a Rust + WebGPU engine, documented in the repo. github.com/shim9610/figgy

Free and open source

figgy is MIT-licensed and runs entirely in your browser tab. No trial period, no locked features, no “upgrade to export” — the studio you see here is the whole product.

We build it in the open because real lab data is the best test a charting engine can get. If something breaks on yours, tell us — that's the whole deal.

Your chart data never leaves your computer. Plotting happens entirely client-side — no account, no upload — so unpublished results stay yours.

01No account, no upload — open the page, drop a file, get a figure. Runs in up-to-date desktop browsers, nothing to install.

02Private by design — unpublished data stays in the tab. Close it and nothing is left behind.

03Honest defaults — the first render is already publication-styled, so the fast path and the right path are the same path.

04Open source (MIT) — inspect it, host it yourself, or build on it. The repo is public on GitHub.

✎Using figgy in a paper? No obligation — but if you'd like to credit it, this line works in a methods or acknowledgments section:
Figures were prepared with figgy, an open-source scientific graphing tool (github.com/shim9610/figgy).
