Reference lines won't show up on chart

Hi everyone,

 

I'm currently writing a script that, eventually, generates charts.  On these charts, I add 6 reference lines.  2 of them just won't show:

 

vlbCharts << Append(
  
  Control Chart Builder(
   Size(800, 500), // Chart size
   Show Two Shewhart Charts(0),
   Show Control Panel(0),
   Show Excluded Region(0),
   Show Limit Summaries(0),
   Show Capability(0),
   Variables(Subgroup(:BatchPrefix), Y(:Value)),
   Chart(
    Points(Statistic("Individual")),
    Limits(Sigma("Moving Range" ), Show Limits(0))
   ),
   SendToReport(
    Dispatch(
     {},
     "Control Chart Builder",
     OutlineBox,
     {Set Title(sProduct ||  ": " || sComponent)}
    ), // Chart title
    Dispatch(
     {},
     "Value",
     ScaleBox,
     {Min(nMinValue), Max(nMaxValue), Inc(nTicks), Minor Ticks(0),
     Add Ref Line(nLSL, "Solid", "Medium Light Orange", "LSL", 1), // Not shown
     Add Ref Line(nUSL, "Solid", "Medium Light Orange", "USL", 1), // Not shown
     Add Ref Line(nLCL, "Solid", "Medium Dark Red", "LCL", 1),
     Add Ref Line(nUCL, "Solid", "Medium Dark Red", "UCL", 1),
     Add Ref Line(nLCL_Calc, "Solid", "Dark Blue", "LCL_Calc", 1),
     Add Ref Line(nUCL_Calc, "Solid", "Dark Blue", "UCL_Calc", 1)}
    ),
    Dispatch(
     {},
     "graph display 1 title",
     TextEditBox,
     {Set Text("")}),
    Dispatch(
     {},
     "Control Chart Builder",
     FrameBox,
     {DispatchSeg(Line Seg(1), {Line Color("Black")} )}
    )
   )
  );
 );

 

The problem is the label "LSL"  and "USL".  When I change these to something else (eg "US" and "LS"), the lines will be displayed:

 

Add Ref Line(nLSL, "Solid", "Medium Light Orange", <STRONG>"LS"</STRONG>, 1), // shows on chart

Add Ref Line(nUSL, "Solid", "Medium Light Orange", <STRONG>"US"</STRONG>, 1), // shows&nbsp;on&nbsp;chart

 

Is there any way I can actually use LSL and USL as labels?

 

Thanks,

 

Jan

ScriptingRe: Reference lines won't show up on chart

This seems to be a bug in the control chart builder platform as it works manually but not in code. I can reproduce the issue on JMP 16 EA8 and have submitted a bug report.

@jan_solo 

This is just a wild guess knowing how JMP labels reference lines. Specify your reference lines with names USL and LSL and add the message to your control chart object.

 

cc_obj << Show Spec Limits(1); 

 

If that doesn't work, an alternative is shown in the JMP > Help > Scripting Index 

 

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Reliability/GaAs Laser.jmp" );
obj = dt << Degradation(
 Y( :Current ),
 Time( :Hours ),
 Label( :Unit ),
 Set Upper Spec Limit( 7.5 )  //set the spec limits
);
obj << Show Spec Limits( 1 );

My fingers are crossed.
