  base_size = 28,
  text_color = "#222222",
  caption_color = "#7D7E81",
  show_legend_title = FALSE,
  show_axis_titles = FALSE,
  grid = FALSE,
  grid_color = "#CBCBCB",
  title_align = "left",
  legend_align = "left",
  caption_align = "right"
)

Arguments

family	Base font family. Defaults to "Halyard Display".
header_family	Font family for title and subtitle. Defaults to the base font family.
base_size	Base font size. Recommended minimum value of 15.
text_color	Text color for titles, axes, legends, and facets.
caption_color	Text color for caption.
show_legend_title	Logical. Should the legend title be shown? Leave as TRUE if you want to change the legend title with a subsequent line + labs(...).
show_axis_titles	Which axis titles should be shown? Use TRUE or FALSE for toggle both titles, or x or y to show just that axis title.
grid	Which grid lines should be shown? Use TRUE or FALSE to toggle all grid lines, or a string combination of X, x, Y, y for major and minor x and y grid lines.
grid_color	Grid line color.
title_align, legend_align, caption_align	Alignment of title, legend, and caption. Accepts left, right, or center.
