Details

theme_gray

The signature ggplot2 theme with a grey background and white gridlines, designed to put the data forward yet make comparisons easy.

theme_bw

The classic dark-on-light ggplot2 theme. May work better for presentations displayed with a projector.

theme_linedraw

A theme with only black lines of various widths on white backgrounds, reminiscent of a line drawings. Serves a purpose similar to theme_bw. Note that this theme has some very thin lines (<< 1 pt) which some journals may refuse.

theme_light

A theme similar to theme_linedraw but with light grey lines and axes, to direct more attention towards the data.

theme_dark

The dark cousin of theme_light, with similar line sizes but a dark background. Useful to make thin coloured lines pop out.

theme_minimal

A minimalistic theme with no background annotations.

theme_classic

A classic-looking theme, with x and y axis lines and no gridlines.

theme_void

A completely empty theme.

theme_test

A theme for visual unit tests. It should ideally never change except for new features.
