What types of charts can be used in dashboards for subgroup-based inspection items?
In SPC analysis, many inspection datasets are collected in subgroups.
For this type of data, how should SPC dashboards be designed for a single inspection item?
For subgroup-based inspection items, we provide six standard SPC dashboard charts.
P1：Xbar Control Chart
P2：R Control Chart
P3：S Control Chart
P4：Xbar Moving Range Control Chart
P5：Process Capability Chart
P6：Subgroup Distribution Chart (Scatter Plot)
In the SPC dashboard shown above:
You can display multiple charts for the same inspection item, or
You can display different charts for different inspection items,
depending on your monitoring and analysis requirements.
