Spreadsheet-Style Data Editor
Edit data in-table, add derived columns with formulas, and assign roles for x/y data and uncertainties.
Scientific plotting, made iterative
Build publication-ready plots in your browser and keep them editable.
pont.ink combines data editing, lmfit-based fitting, annotation, and export into one workflow. You can revisit and continue work later from saved sessions and metadata-enabled exports.
Interactive Fit Workflow
Select fit regions directly on the plot, tune initial parameters and bounds, and update results in context.
Reproducible Exports
Export PNG, SVG, or PDF plus generated Matplotlib code. Session metadata can be embedded for later reload.
How pont.ink works
- Load data: import CSV/TSV or type directly into the editor.
- Shape the figure: adjust axes, title, legend, overlays, and annotations.
- Fit models: choose a region, configure parameters, and inspect fit quality.
- Export and continue: save outputs and reopen editable sessions whenever needed.
