Fantasality/dsh-origin-plugin

New here? Start with the Beginner's Quickstart — four ways to run it (Origin button / copy-paste scripts / MCP client / inside DSH), pick yours, done in 1–3 minutes. This page is the capability reference; the Chinese README.md is authoritative.

Drive OriginLab Origin from AI chat over MCP — on your own machine, over COM, with no network round-trip to anyone else's server.

Why this instead of a text-to-figure tool

The deliverable is an editable Origin project file (OPJU) plus a reproducible FigureSpec YAML — every line, marker and axis property stays hand-tunable in Origin and reproducible months later. Text-to-figure / text-to-SVG routes (AutoFigure-like) emit one-off vector objects aimed at method diagrams, not experimental data plots; editability granularity and scientific reproducibility are on different levels.

Install

Requirements: Windows, Origin 2021+ (2026 tested), Python 3.10+.

Fast path: one call, one figure

{"columns": {"x":[1,2,3,4,5], "y":[1,4,9,16,25]}, "intent": "journal", "fmt": "png"}

origin_figure does import → plot → verify → export → (optional) delivery in a single call (~1 s). The old route took 6–10 tool round-trips; because ~80% of perceived latency is model decision turns, collapsing the turns is what actually makes it feel fast.

What's in the box (70 tools / 34 error codes)

• Plotting — 2D (line/scatter/line-symbol/column/histogram/box/bar/error bars), 3D, contour, domain templates (stacked spectra, XRD triple, dual-Y, forest, multi-panel)
• Fine-grained editing — per-curve color/width/symbol/visibility, axis, legend anchors, page geometry, window management, remove/swap curves, sort/transpose
• Analysis — fitting with initial/fixed/weighted params, peak analysis, statistics batch (t-test / ANOVA / PCA / Kaplan-Meier), FFT, integration, correlation
• Matrix tools — write / read / plot matrices (surface, contour, wireframe)
• Bridges — matplotlib figure → Origin, PowerPoint assembly with panel letters, OriginLab Graph Gallery template search, EPS/SVG/PDF/TIF/EMF export
• Reusable style templates — save a finished graph as a template and apply it to others (lab-wide consistent styling)
• Trust layer — readback graded verified / readback_only / unverified, modal-dialog watchdog, LabTalk destructive-command gate, export file-magic validation, 12-image dHash visual regression baseline, stable error codes with a recovery map
• Declarative — FigureSpec YAML (diff-able, replayable), MCP Resources read-only snapshots

Science boundaries

No fabricated data · uncertain columns raise a confirmation question · derived columns are labelled · statistics carry a confidence note · unsupported operations are refused explicitly rather than silently ignored. 15 measured failure modes are documented in COMPATIBILITY.md.

Test

python -m pytest tests/ -q              # offline tests always; live tests skip without Origin
python origin_mcp_server.py --offline-test
python origin_mcp_server.py --selftest  # full chain, needs Origin
