The Process Capability chart helps define the data distribution by illustrating minimum and maximum values in relation to the median. A Histogram Curve Chart is the traditional default chart type that opens in GainSeeker when a new Process Capability chart is created. However, the chart type can be changed.
Note: A minimum of five data values are needed to display this chart for a data distribution. These can come from: five or more data records with a subgroup size of one; three or more data records with a subgroup size of two; two or more data records with a subgroup size of three or four, or one or more data records with a subgroup size of five or more.
Navigate to the Process capability chart options by following this path on the Settings tab:

You can also select default chart settings in the GainSeeker System Administration module. See Chart Defaults settings
