Built-in themes

In addition to making your own themes, there are several out-of-the-box solutions that may save you lots of time.

  • theme_gray() is the default.
  • theme_bw() is useful when you use transparency.
  • theme_classic() is more traditional.
  • theme_void() removes everything but the data.

plt_prop_unemployed_over_time is available.
