Making changes on the control chart graph in R (qic function)
How can I force R to show all the data points on the x-axis of the control chart (from qic function)? Also how can I add data labels to the data points on the control chart?
Here is my data and the 'qic' function I used to create the graph:
d <- data.frame(week = seq.Date(as.Date('2016-06-06'),by ='week',length = 35,cex=0.25),y)
qic(y, x = week, data = d[1:24,], chart ='i',main='Statistical Process Control Chart',xlab='Week-Year', ylab='y')
