export-igorgraph 0.1.1

First public release.

export-igorgraph turns a matplotlib figure into an editable Igor Pro graph:
export_igor(fig, outdir, name) writes one HDF5 file (data + Igor drawing commands),
and LoadPythonFigure in Igor draws it.

See README (EN) / README (JP) for details.

Claude skill

export-igorgraph-public.skill (attached in this page) is a skill file for Claude.ai (upload it in the skill settings) and Claude Code (unzip it into ~/.claude/skills/). It bundles the Python package and keeps your default formatting in export_igorgraph_style.json.

Highlights

• Lines (solid and dashed), 20 marker shapes (5 of them approximated, with a warning), error bars with caps, log axes (10^n labels), grid, tick direction, legends, labels
• Scatter plots with one color and size (per-point colors/sizes: the first value is used, with a warning)
• Images, color maps, framed color scale
• Contours drawn as real Igor contours (AppendMatrixContour / ModifyContour) from the original Z matrix (matplotlib 3.8+)
• Main formatting via style= or a style file: tick, mirror, standoff, grid, width, height, font, gFont
• The Igor loader runs only commands that match a strict allow-list and rejects the whole file otherwise
• Anything Igor cannot reproduce is reported in report.warnings, never dropped silently

Install

1. pip install export-igorgraph (or pip install git+https://github.com/nlyamada/export-igorgraph)
2. Open ExportIgorGraphLoader.ipf (attached in this page), or copy to Igor procedure folder Documents\WaveMetrics\Igor Pro * User Files\Igor Procedures\ and restart Igor.
3. In Igor: Macros > LoadPythonFigure

Status

• Verified on Igor Pro 8.04 / Windows only. Other Igor versions and macOS are unverified — reports welcome.
• Python 3.9+. CI runs matplotlib 3.6.3, 3.8.4, 3.9.4 and 3.10.7 (contours need 3.8+).

See the CHANGELOG and the documentation.
