I have a script where I generate a control chart from the builder. I basically just formatted the chart how I wanted manually and then saved the script to script window and used that in my script. The problem is that even though in the making of the graph I had eliminated the moving range portion of the chart and then saved the script the moving range keeps coming back. I know that you are supposed to use the syntax: Show Two Shewhart Charts( 0 ), to remove the moving range but even though it is in the script it doesn't eliminate it. The script is as follows:
lower_spec = num(Col Mean( LowerSpec ));
upper_spec = num(Col Mean( UpperSpec ));
up_control = num(ucont);
low_control = num(lcont);
max_number = num(col max(column(4)));
min_number = num(col min(column(4)));
if(max_number > upper_spec, chart_max = max_number,chart_max = upper_spec);
if(min_number < lower_spec, chart_min = min_number,chart_min = lower_spec);
Control Chart Builder(
Show Two Shewhart Charts( 0 ),
Size( 450, 900 ),
Show Control Panel( 0 ),
Include Missing Categories( 0 ),
Variables( Subgroup( :lot ), Y( :column( 4 ), Individual Measurement) ),

Add Spec Limits( {LSL( lower_spec ), USL( upper_spec ), Target( desired )} )
),
SendToReport(

ScaleBox,

Add Ref Line( desired, "Solid", "Blue", "Target", 1 ),
Add Ref Line( low_control, "Solid", "Red", "LCL", 1 ),
Add Ref Line( up_control, "Solid", "Red", "UCL", 1 )
}
),
Dispatch( {"Process Capability Analysis", "Histogram"}, "Process Capability Analysis Histogram", FrameBox, {Frame Size( 150, 18 )} ),
Dispatch(

"Process Capability Analysis Histogram",
FrameBox( 2 ),
{Frame Size( 150, 160 )}
),
Dispatch( {"Process Capability Analysis", "Process Summary"}, "Within sigma estimated by moving range.", TextBox, {Set Wrap( 75 )} )
)
);
Is it a bug that needs to be addressed or am I not coding this right?
Thanks in advance for any help.
