Plot themes

Control the non-data look of a plot. theme_gray() is the default (grey panel, white gridlines); theme_minimal() drops the panel fill for light gridlines on the page; theme_bw() is a white panel with light grey gridlines; theme_classic() has axis lines and no gridlines; theme_void() strips everything but the marks, legend, and titles; theme_cyberpunk() is a dark neon theme (see Details).

Usage

theme_gray(plot)

theme_minimal(plot)

theme_bw(plot)

theme_classic(plot)

theme_void(plot)

theme_cyberpunk(plot)

theme(plot, ...)

set_theme(
  plot,
  panel_bg = NULL,
  grid_col = NULL,
  label_col = NULL,
  strip_bg = NULL
)

Arguments

plot

A PlotSpec.

...

Named theme elements, e.g. plot.title = element_text(size = 16), panel.grid.minor = element_blank(), or settings like legend.position, one of "right" (default), "left", "top", "bottom", or "none". Legend geometry is tunable via legend.key.size (key/swatch side, mm), legend.spacing (gap between stacked guides, mm), and legend.margin (inset around the legend block, one or four millimetres, t, r, b, l).

panel_bg, grid_col, label_col, strip_bg

Colours (or NA to draw nothing) for the panel background, gridlines, axis-label/legend text, and facet strip background.

Value

The modified PlotSpec.

Details

theme() overrides individual elements on top of the current theme using element_text() / element_line() / element_rect() / element_blank(). set_theme() is a small back-compatible shortcut for the most common colours.

theme_cyberpunk() sets a dark canvas with dim neon gridlines and a bright neon default palette (both discrete and continuous), in the spirit of mplcyberpunk. It pairs with the glow() layer effect and linear_gradient() fills for the full neon look; the palette is only a default, so scale_* overrides still win.

Examples

vplot(mtcars) |> mark_point(x = wt, y = mpg) |> theme_minimal()

vplot(mtcars) |>
  mark_point(x = wt, y = mpg) |>
  theme(panel.grid.minor = element_blank(), legend.position = "none")
