• Appropriate control chart selection and subgroup distribution
• Process Capability Analysis Report：
• Cpk, Ppk, PPM
• Distribution charts and fitted curves
• Normal probability plots and capability comparison charts
• Normality tests and distribution fitting tests
• Machine-learning-based anomaly detection charts
• Statistical summary tables and capability tables
• Raw data details and rainbow charts
• Historical out-of-control events and corresponding improvement actions

Supported SPC Analysis Types

Individual data

• I–MR charts

Fixed subgroup

• Xbar charts
• R charts
• S charts
• MR–R/S charts
• Xbar moving range charts

Variable subgroup size

• Xbar charts
• R charts
• S charts

Attribute data

• NP charts

5. SPC Dashboards

As manufacturing digitalization advances, dashboards are widely used on the shop floor to produce production status, such as order progress and workstation load.

Quality management follows the same visualization approach by：

• Deploy real-time SPC dashboards at any production station or line
• Monitor quality anomalies for specific workstations, lines, or orders

Dashboard Capabilities

• Unlimited number of dashboards
• Unlimited charts per dashboard
• Each dashboard has a dedicated URL, ideal for large-screen displays
• Supported visualizations:
• SPC control charts
• Pre-control (rainbow) charts
• Capability histograms
• All charts update in real time

Dashboard Types

1. Real-time dashboards
2. Comprehensive dashboards
3. Statistical dashboards and custom charts

6. SPC Monitoring & Alerts

1）Monitoring Configuration
