Control Chart (SPC)

Statistical Process Control charts with Western Electric rules detection. Displays control limits (UCL/LCL), warning limits, and zones (A/B/C). Automatic violation detection for rules 1-4. Use cases: Manufacturing quality control, process monitoring, Levey-Jennings charts (medical labs), SPC analysis, out-of-control detection.

Installation

Copy and paste the following code into your project.

npx @plexusui/cli add control-chart

Manual Installation

1. Copy the component code from components/control-chart.tsx

2. Install dependencies:

npm install react@latest

3. Copy any required primitive components

Examples

Basic Control Chart (In Control)

Process monitoring with 3-sigma control limits (UCL/LCL) and Western Electric rules

Outlier Detection (Rule 1)

Single point beyond 3-sigma limit detected - possible measurement error or special cause

High Variation Process

Process with larger standard deviation (4 vs normal 2) - still in control but wider limits

Custom Control Limits

Manually specified limits based on engineering specifications (target ± tolerance)

Selective Western Electric Rules

Apply only specific rules (Rule 1 and Rule 4) for targeted monitoring
