There is an option in QCC to fill the zones with colors. I have tried calling this option in my code but I don't think I understand how to call it or provide the arguments correctly and I am stuck, stuck, stuck. Picture below shows zones filled and not filled and the documented examples. Somewhere I'm missing either the proper syntax for invoking the fill or I'm missing something not so obvious to me.
I have tried the following variations from the documentation without success:
qcc.options("zones")$fill
I put the fill = TRUE in the code that plots my chart as the example shows. It doesn't throw an error but it doesn't do the fill.
cht <- qcc(v, type="xbar.one", plot = "FALSE" , labels = xticks )
plot(cht, restore.par =FALSE, fill= TRUE, title = "", xlab = "", ylab = "moisture %", axes.las = 2, add.stat = FALSE )
