I'm trying to change the x-axis of a control chart that I am generating an XBAR plot. I have 131 subgroups and would like to label each one individually. I think it has something to do with 'parent' but I am unfamiliar with it.

Jason, from your description it sounds like you want to do this:

x = randn(131,4);
controlchart(x)
set(gca,'xtick',1:131)

However, it is likely you won't be happy with the results. Maybe if you also
look into the 'XMinorTick' option you will be happier.
