SPC Chart

Welcome to the KensoBI SPC Chart panel for Grafana. This plugin enables you to easily create statistical process control (SPC) charts, including Xbar-R, XbarS, and XmR charts. It automatically calculates and displays control limits, with options to add your own custom limits. Additionally, you can group your samples into subgroups and aggregate them using methods such as moving range, range, mean, or standard deviation.

Features

• Xbar-R, XbarS, and XmR Charts: Create various types of SPC charts with a single click.

• Automatic Control Limits: LCL (Lower Control Limit), UCL (Upper Control Limit), and mean are automatically calculated and displayed.

• Custom Limits: Add your own limits for more tailored analysis.

• Subgrouping: Group your samples into subgroups for analysis.

• Aggregation: Aggregate your data by moving range, range, mean, or standard deviation.
