These are complete themes which control all non-data display. Use
\code{\link[=theme]{theme()}} if you just need to tweak the display of an existing
theme.

\details{
\describe{

\item{\code{theme_gray()}}{
The signature ggplot2 theme with a grey background and white gridlines,
designed to put the data forward yet make comparisons easy.}

\item{\code{theme_bw()}}{
The classic dark-on-light ggplot2 theme. May work better for presentations
displayed with a projector.}

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

\item{\code{theme_light()}}{
A theme similar to \code{theme_linedraw()} but with light grey lines and axes,
to direct more attention towards the data.}

\item{\code{theme_dark()}}{
The dark cousin of \code{theme_light()}, with similar line sizes but a dark background. Useful to make thin coloured lines pop out.}

\item{\code{theme_minimal()}}{
A minimalistic theme with no background annotations.}

\item{\code{theme_classic()}}{
A classic-looking theme, with x and y axis lines and no gridlines.}

\item{\code{theme_void()}}{
A completely empty theme.}

\item{\code{theme_test()}}{
A theme for visual unit tests. It should ideally never change except
for new features.}
