washi_theme {washi}R Documentation

Create standard WaSHI plots

Description

All changed defaults from this function can be overridden by another call to ggplot2::theme() with the desired changes.

Usage

washi_theme(
  header_font = "Lato Black",
  header_color = "#151414",
  body_font = "Poppins",
  body_color = "#151414",
  text_scale = 1,
  legend_position = "top",
  facet_space = 2,
  color_gridline = washi_pal[["standard"]][["tan"]],
  gridline_y = TRUE,
  gridline_x = TRUE,
  ...
)

Arguments

header_font

Font family for title and subtitle. Defaults to "Lato Black".

header_color

Font color for title and subtitle. Defaults to almost black.

body_font

Font family for all other text Defaults to "Poppins".

body_color

Font color for all other text Defaults to almost black.

text_scale

Scalar that will grow/shrink all text defined within.

legend_position

Position of legend ("none", "left", "right", "bottom", "top", or two-element numeric vector). Defaults to "top".

facet_space

Controls how far apart facets are from each other.

color_gridline

Gridline color. Defaults to WaSHI tan.

gridline_y

Boolean indicating whether major gridlines are displayed for the y axis. Default is TRUE.

gridline_x

Boolean indicating whether major gridlines are displayed for the x axis. Default is TRUE.

...

Pass any parameters from theme that are not already defined within.

Value

ggplot2 object
