[R] X axis labels are not fully shown when using pareto.chart function

Wed Sep 16 16:49:02 CEST 2020

The following works:

library(qcc)
x = dataset2$Points 
names(x) = dataset2$School
par(oma = c(2,0,0,0))
pareto.chart(x)

You may need to adjust the oma parameter. 

BTW, next time please provide a reproducible example. I spent more time to figure out which is the correct variable/label to plot than to find the solution to your problem.
