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

Wed Sep 16 06:54:44 CEST 2020

Hi Paul,
It is a contest between the quantity of information and legibility.
You have 140 labels to place on the x-axis in your plot and I barely
managed it by almost doubling the width of the plot, halving the size
of the font and truncating the labels to a maximum of 20 characters.
Unless you want to follow something like Google Maps, where the
information springs up in a little balloon, you are close to the
limits of a static display. That said, you are correct in saying that
staxlab will cram a lot of information at the edges of a plot.
