How to change 'µ0' to 'mean' on a control chart?

Hi,

When I run a control chart, the average is expressed as 'µ0'.  This is not incorrect, however, our quality department would like to see 'Mean' instead.  Is there a way to change the label from 'µ0' to 'Mean'?

Thanx

Names Default To Here( 1 );

dt = Open( "$SAMPLE_DATA/Quality Control/Coating.jmp" );

obj = Control Chart( Sample Size( :Sample ), Chart Col( :Weight, XBar, R ), Get Limits( "$SAMPLE_DATA/Quality Control/CoatingLimits.jmp" ) );

Unfortunately, there's no good way to override that labeling. That's what we use to indicate the limits are specified rather computed.

The Control Chart Builder platform handles this a bit differently. It provides a Limits Summaries report instead of labeling the limits lines.

dt = Open(


  "$SAMPLE_DATA/Quality Control/Coating.jmp"


);


obj =


Control Chart Builder(


  Variables(


  Subgroup( :Sample ),


  Y( :Weight )


  ),


  Chart(


  Position( 1 ),


  Points( Statistic( "Average" ) ),


  Limits( Sigma( "Range" ) )


  ),


  Chart(


  Position( 2 ),


  Points( Statistic( "Range" ) ),


  Limits( Sigma( "Range" ) )


  ),


  Get Limits(


  "$SAMPLE_DATA/Quality Control/CoatingLimits.jmp"


  )


);

Thank you.  It might not be the answer I was looking for, but I did expect it, since I could not access the 'µ0' label using the GUI.
