Why this tool is operated
Sakura Chart is an independently operated chart-making tool created from practical experience preparing charts for experiments, data checks, reports, and presentations. It focuses on workflows that are cumbersome in spreadsheet software: splitting charts by a LEVEL column, drawing group-specific regression lines, comparing shared and individual contour ranges, and exporting generated charts together with source data and statistics.
How we handle results and corrections
Input data is used to generate charts and is not presented as public content. Generated charts and statistical values depend on the supplied data and selected settings, so users should verify units, missing values, axis ranges, and calculation conditions before using them in a report. Feature requests, reproducible error reports, and corrections are accepted at the email address above.
