Editing Control Chart after Creation

DavidLeber

I'm trying to create a script to format the output of the Process Screening tool's control charts so they're more pretty. Obviously, I can't go in and change the code of the Process Screening tool itself, so the problem I'm faced with is:

 

Given a preexisting control chart object, how can I:

1. Add a column to the subgrouping

2. Delete the Moving Range graph

 

For reference, I currently have a myControlChart object on which I was able to successfully run myControlChart<<showLimitSummaries(0);.

I was able to find a solution! The key was getting the graph builder box.

 

 

var = Current Report();    //Returns a reference to the report that's currently open, i.e. the Control Chart generated by Process Screening

gbb = var[GraphBuilderBox( 1 )];    //Returns a reference to the actual Graph

gbb << removeVariable( 1 );&nbsp; &nbsp; //This is a case of lucky guess - not sure why this removes the moving average chart, but it does.

gbb << addVariable( {:Month, Role( "Subgroup" )} );&nbsp; //Adds the month to the "X Axis" of the control chart.

 

 

I hope this helps anyone in the future!
