Setting themes

Reusing a theme across many plots helps to provide a consistent style. You have several options for this.

  1. Assign the theme to a variable, and add it to each plot.
  2. Set your theme as the default using theme_set().

A good strategy that you'll use here is to begin with a built-in theme then modify it.

plt_prop_unemployed_over_time is available. The theme you made earlier is shown in the sample code.
