Control Chart

Example 1

Summary: Create a control chart with individual measurement, no center line, and no control limits.

Code:

// Open data table
dt = Open("$Sample_Data/DiceRolls.jmp");
// Plot Results
Control Chart(
    KSigma( 3 ),
    Range Span( 1 ),
    Chart Col(
        :Average,
        Individual Measurement(
            Show Center Line( 0 ),
            Show Control Limits( 0 )
        )
    )
);

Example 2

Summary: Create a U Chart with a Weighted Moving Average Chart (UWMA) for a sample data table in the Quality Control platform.

Code:

// Open data table
dt = Open("$Sample_Data/Quality Control/Clips1.jmp");
// UWMA Chart
Control Chart(
    Sample Label( :Status ),
    Sample Size( 5 ),
    K Sigma( 3 ),
    Moving Average Span( 2 ),
    Chart Col( :Gap, UWMA )
);

Example 3

Summary: Generate a Unweighted Moving Average (UWMA) control chart with a sample size of 5, a moving average span of 2, and 3-sigma control limits.

Code:

// Open data table
dt = Open("$Sample_Data/Quality Control/Clips2.jmp");
// UWMA Chart
Control Chart(
    Sample Label( :Date ),
    Sample Size( 5 ),
    K Sigma( 3 ),
    Moving Average Span( 2 ),
    Chart Col( :Gap, UWMA )
);
