README

FigDataX

**Fig**ure **Data** e**X**traction — high-precision scientific figure data extraction, as an agentic **Claude Code skill**.

Give Claude a figure image (or several) cropped from a paper; it extracts the numbers at up to **±0.5% accuracy** and proves it with a validation overlay. The engine measures the geometry (plot area, tick pixel positions, series colors, sub-pixel centroids); Claude reads the semantics (tick values, legend) with vision; you are asked only when something is genuinely ambiguous.

Supported: scatter, line, bar (grouped/stacked), box, pie, heatmap, polar, error bars, log axes, multi-panel figures. Output: CSV per figure + optional multi-sheet Excel with provenance (method, calibration RMSE, validation rounds).

中文说明见 [中文说明.md](中文说明.md)。

Install

git clone https://github.com/Shaowen-Ye/FigDataX ~/.claude/skills/FigDataX
bash ~/.claude/skills/FigDataX/scripts/setup.sh      # creates .venv, installs deps (uv)
~/.claude/skills/FigDataX/.venv/bin/python -m scripts.figdatax self-test

The folder name is **`FigDataX`** (case-sensitive on Linux).

Use

In Claude Code, just ask:

> 提取 /path/to/figure.png 图片数据
> Extract data from ./results/fig3.png
> 这几张图都提取一下，汇总成一个 Excel

Claude runs the autonomous loop in [SKILL.md](SKILL.md): classify the chart → engine geometry pass (`figdatax geometry`: bbox + tick positions + series colors) → visually verify the annotated overlay → pair tick values by vision → calibrate (hard RMSE < 1% gate) → extract sub-pixel centroids → visually check the validation overlay → iterate up to 3 rounds → deliver CSV/Excel + a provenance report.

Zero-typing entry points (macOS)

bash ~/.claude/skills/FigDataX/integrations/macos/install.sh

installs two shortcuts so you barely type at all:

/figx slash command — in Claude Code, type /figx and drag the image(s) into the terminal. Full interactivity (Claude can still ask at the two gates).
