Themes - janeshdev/ggplot2 GitHub Wiki
Proposed themes and theme enhancements.
minimalistic theme to maximize data/ink ratio, so as to focus more strongly on the data glyphs. It also serves to facilitate post-processing in graphic design software (Illustrator, Inkscape)

<script src="https://gist.github.com/2594954.js?file=ggplot2%20theme_minimal"></script>Comment: I like the axis ticks and text and panel border rectangle in more similar colour: so either
theme_minimal_cb <- function (base_size = 12, base_family = "", ...){
modifyList (theme_minimal (base_size = base_size, base_family = base_family),
list (panel.border = theme_rect(fill = NA, colour = "grey50")))
}
theme_minimal_cb_L <- function (base_size = 12, base_family = "", ...){
modifyList (theme_minimal (base_size = base_size, base_family = base_family),
list (axis.line = theme_segment (colour = "black")))
}
or (a very light version)
theme_minimal_light <- function (base_size = 12, base_family = "", ...){
modifyList (theme_minimal (base_size = base_size, base_family = base_family),
list (axis.ticks = theme_segment (colour = "grey50"),
axis.text.x = theme_text (colour = "grey33"),
axis.text.y = theme_text (colour = "grey33")))
}
Maximize the plotting area so as to extend over the full viewport. Axis labels and titles are masked; this theme is therefore limited to special graphs such as images where full control over the image size is required (e.g. for alignment with other graphical elements).
theme_fullframe <- function (base_size = 12){
structure(list(
axis.line = theme_blank(),
axis.text.x = theme_blank(),
axis.text.y = theme_blank(),
axis.ticks = theme_blank(),
axis.title.x = theme_blank(),
axis.title.y = theme_blank(),
axis.ticks.length = unit(0, "lines"),
axis.ticks.margin = unit(0, "lines"),
legend.position = "none",
panel.background = theme_blank(),
panel.border = theme_blank(),
panel.grid.major = theme_blank(),
panel.grid.minor = theme_blank(),
panel.margin = unit(0, "lines"),
plot.background = theme_blank(),
plot.margin = unit(0*c(-1.5, -1.5, -1.5, -1.5), "lines")
), class = "options")
}
A black theme for black background presentations. Note that using this typically involves changing the colour/fill aesthetics for viewing.
theme_black <- function (base_size = 12){
structure(list(
axis.line = theme_blank(),
axis.text.x = theme_text(size = base_size * 0.8, colour = 'white', lineheight = 0.9, vjust = 1),
