Scientific graph generator in your browser: spreadsheet data entry, auto-calculated means, bar and scatter plots, custom error bars, curve fits, significance brackets, and high-resolution export.
Enter data in the grid or upload CSV, choose a chart type, and customise axes, bars, points, and fit lines. Add significance brackets between groups. All processing runs locally.
Long format: Group + Value columns (optional Label, X, Err +/−). Wide matrix
format: row 1 = replicate names (set1, set2…), col A = category (fill-down), col B = treatment
(control, drug), remaining columns = values — like test data.csv. Paste from Excel or upload.
