Themes

Six presets, and 35 individual settings you can override with theme(). Every setting travels inside the geometry buffer, so the static and interactive targets always agree.

`theme_ggnext()` — The default: a softly tinted panel with white gridlines.

`theme_minimal()` — No panel fill, light grey grid, no axis lines or ticks.

`theme_classic()` — White panel, black axes, no grid, serif type - the statistical-journal look.

`theme_modern()` — Editorial styling: large title, horizontal rules only, a brighter palette.

`theme_dark()` — Dark background with a palette tuned for it.

`theme_void()` — No chrome at all - for treemaps, networks, and sparkline-style output.

Customizing

Override any setting on top of any preset. base picks the preset to start from; everything else is applied over it.

ggnext(cars, aes(speed, dist)) + geom_point() +
  theme(
    base = theme_minimal(),
    panel_fill = "#FFF8F0",
    grid_major_x = FALSE,
    plot_title_size = 22,
    legend_position = "bottom",
    point_palette = c("#2B6BE0", "#E05A2B", "#12A594")
  )

Colour settings accept any R colour specification - a name like "steelblue" or a hex string. An empty string "" means do not draw this element, which is how grid_color = "" removes gridlines entirely.
