Select numbers on a page, or paste cells from a sheet, and chart them in LimitLine: control chart, Cpk, Pareto and more. New in 1.1: optional spec limits in the paste box. Enter a lower and/or upper limit and LimitLine opens with Cp and Cpk already calculated. A decimal comma (11,5) works too. Still no account, nothing stored, nothing uploaded. Turn numbers you're looking at into a control chart in one step. Select measurements on any web page, right-click and choose "Chart selected numbers in LimitLine". Or copy a column from Google Sheets or Excel, click the LimitLine button (or press Alt+Shift+L), paste, and press Chart. LimitLine opens with your numbers already charted: an Individuals (I-MR) control chart with limits and rule signals. Add your spec limits to see Cp and Cpk with a confidence range. Copied a whole table? LimitLine shows it so you pick which column to chart. Private by design • The extension reads only what you select or paste, only when you ask. • Your numbers travel after the # in the address, the part browsers never send to a server, and LimitLine works them out on your computer. • The extension stores nothing and sends nothing anywhere. No account, no sign-in. What you get • Free plan: I-MR chart with all 8 Nelson rules (5 on by default), Cp/Cpk/Pp/Ppk with histogram, Pareto and run charts, and a Cpk sample-size calculator. • Pro, in the same app, for those who need it: subgroup and attribute charts, Capability+, hypothesis tests, regression, Gauge R&R, DOE and more. See limitline.org for plans. I built LimitLine as a Lean Six Sigma Black Belt who wanted SPC without installing anything.
