process.capability S3 example for plot

[ellis-geoff]

The end effect I'm looking to achieve is simply set a fill color for the histogram boxes..

I have been unable to figure out how to set the fill color through par, qcc.options or process.capability arguments. The help doc seems to imply there is a way to use the S3 method with plot but I have not been able to make that work. And it's not part of the current examples anymore ...also the current examples to work either errors on gcc.groups ( older version had example using plot too )

S3 method for process.capability

plot(x,
add.stats = qcc.options("add.stats"),
breaks = "scott",
col = adjustcolor(qcc.options("zones")$fill, alpha.f = 0.5),
border = "white",
digits = getOption("digits"),
restore.par = TRUE, …)
