A dodged bar chart is produced when a
fill= option is provided for
the ggplot2::aes() and
position="dodge" option for the
ggplot2::geom_bar(). We can add numeric labels using
ggplot2::geom_label() (as in Section 11.14) or
using ggplot2::geom_text() (as in Section
11.19). Here we demonstrate with
Notice the use of scales::comma() for the labels as should be standard practice.
To tune the plot we’ve moved the legend to the top with the
legend.position="top" option of ggplot2::theme(), increased the
y-axis to fit the label using the
limits= option of the
ggplot2::scale_continuous() family of functions.
We have also chosen ggthemes::theme_solarized_2() for a different style of presentation. Notice that the ggplot2::theme() is placed after the ggthemes::theme_solarized_2() to override the default of the theme which is to place the legend on the right.
