This prerequisite is explained when you hover over the corresponding selection box:
2. To use user-defined centerline, select "Use defined centerline" as the Centerline type under General tab
3. To use user-defined control limits, select "Use defined UCL and LCL" as the Control limits
4. To use user-defined specification limits, select "Use LSL, Nominal, and USL" as the Specification limits
5. Run the node after the configuration, a control chart will be generated:
