Quick charts from pasted data — scatter / box plot + regression (with steps, PNG/PDF)

Why use Quick Charts?

Automatic delimiter and decimal detection for CSV, TSV, and semicolon spreadsheets.
Compare OLS, Theil–Sen, and up to cubic polynomial regression with step-by-step formulas.
Export classroom-ready PNG/SVG/PDF visuals and CSV configuration snapshots for reproducibility.

Build your chart

Paste your dataset, confirm the detected format, then choose the columns to plot. Use Sample A for regression or Sample B for box plots.

Workflow tips

Use Parse after pasting data to confirm delimiter and header detection, then switch between Scatter and Box tabs without re-uploading.

Share stores key settings in the URL. Reopen the link to reproduce the same regression and chart exports.

Frequently asked questions

How do I prepare pasted spreadsheet data for Quick Charts?

Keep your header row and paste directly from Excel, Sheets, or CSV. Quick Charts auto-detects the delimiter and decimal mark, and you can override the detection if your locale uses comma decimals or semicolon separators.

Can I export the regression results and steps?

Yes. Export the visual as PNG or SVG, print to PDF, and copy the How it's calculated list. You can also export the configuration as CSV to recreate the chart later.
