Capability against a tolerance in Web Component

Cp, Cpk, Pp and Ppk from one column declaration

grid.statistics.capability(col, { baseline })

This grid computes Cp, Cpk, Pp and Ppk from a single column declaration with its tolerance. It tells a quality engineer whether a process fits within its spec, straight from the readings, without exporting to a separate tool.

Building…

Loading a live grid…

This is the web component version. A lattice-grid custom element renders the grid with no build step, its configuration set as a property, so it works on a page that has no bundler at all.

The configuration

  out.textContent = JSON.stringify(el.grid.statistics.capability('bore', { baseline: 20 }), null, 2);
