\subsection{Style Options} \label{sec:styles} \subsubsection{All Supported Styles} \PGFPlots\ provides many styles to customize its appearance and behavior. They can be defined and changed in any place where keys are allowed. Furthermore, own styles are defined easily. \begin{handler}{{.style}=\marg{key-value-list}} Defines or redefines a style \meta{key}. A style is a normal key which will set all options in \marg{key-value-list} when it is set. Use |\pgfplotsset{|\meta{key}|/.style={|\meta{key-value-list}|}}| to (re-) define a style \meta{key} in the namespace |/pgfplots|. \end{handler} \begin{handler}{{.append style}=\marg{key-value-list}} Appends \marg{key-value-list} to an already existing style \meta{key}. This is the preferred method to change the predefined styles: if you only append, you maintain compatibility with future versions. Use |\pgfplotsset{|\meta{key}|/.append style={|\meta{key-value-list}|}}| to append \marg{key-value-list} to the style \meta{key}. This will assume the prefix |/pgfplots|. \end{handler} \subsubsection*{Styles installed for linear/logarithmic axis} \begin{stylekey}{/pgfplots/every axis (initially empty)} Installed at the beginning of every axis. \Tikz\ options inside of it will be used for anything inside of the axis rectangle and any axis descriptions. \end{stylekey} \begin{stylekey}{/pgfplots/every semilogx axis (initially empty)} Installed at the beginning of every plot with linear $x$~axis and logarithmic $y$~axis, but after `|every axis|'. \end{stylekey} \begin{stylekey}{/pgfplots/every semilogy axis (initially empty)} Likewise, but with interchanged roles for $x$~and~$y$. \end{stylekey} \begin{stylekey}{/pgfplots/every loglog axis (initially empty)} Installed at the beginning of every double--logarithmic plot. \end{stylekey} \begin{stylekey}{/pgfplots/every linear axis (initially empty)} Installed at the beginning of every plot with normal axis scaling. \end{stylekey} \subsubsection*{Styles installed for single plots} \begin{stylekey}{/pgfplots/every axis plot (initially empty)} Installed for each plot. This style may contain options like samples, gnuplot parameters, error bars and it may contain options which affect the final drawing commands. \end{stylekey} \begin{stylekey}{/pgfplots/every axis plot post (initially empty)} This style is similar to |every axis plot| in that is applies to any drawing command in |\addplot|. However, it is set \emph{after} any user defined styles or |cycle list| options. \begin{codeexample}[] \begin{tikzpicture} \pgfplotsset{ every axis plot post/.append style= {mark=none}} \begin{axis}[ legend style={ at={(0.03,0.97)},anchor=north west}, domain=0:1] \addplot {x^2}; \addplot {exp(x)}; \legend{$x^2$,$e^x$} \end{axis} \end{tikzpicture} \end{codeexample} \end{stylekey} \begin{stylekey}{/pgfplots/every axis plot no \# (initially empty)} Used for every \#th plot where $\#=0,1,2,3,4,\dotsc$. \end{stylekey} \begin{stylekey}{/pgfplots/every forget plot (initially empty)} Used for every plot which has |forget plot| activated. \end{stylekey} \pgfplotsshortstylekey forget plot style=every forget plot\pgfeov \subsubsection*{Styles for axis descriptions} \begin{stylekey}{/pgfplots/every axis label (initially empty)} Used for all axis label (like |xlabel| and |ylabel|). \end{stylekey} \pgfplotsshortstylekey label style=every axis label\pgfeov \begin{xystylekey}{/pgfplots/every axis \x\ label} Used only~$x$ or only for~$y$ labels, installed after `|every axis label|'. The initial settings are set by |xlabel absolute| and its variants (if the initial configuration |compat=pre 1.3| is active) or |xlabel near ticks| which provides the better spacing as it incorporates the tick label sizes to compute the position. \paragraph{Attention:} These styles will be overwritten by |axis x line| and/or |axis y line|. Please remember to place your modifications after the axis line variations. \end{xystylekey} \pgfplotsshortxystylekeys \x\ label style,\x label style=every axis \x\ label\pgfeov \begin{stylekey}{/pgfplots/every axis title} Used for any axis title. The |at=|\parg{x,y} syntax will place the title using |axis description cs|. The initial setting is \begin{codeexample}[code only] \pgfplotsset{every axis title/.style={at={(0.5,1)},above,yshift=6pt}} \end{codeexample} \end{stylekey} \pgfplotsshortstylekey title style=every axis title\pgfeov \begin{stylekey}{/pgfplots/every axis legend} Installed for each legend. As described for |axis description cs|, the legend's position can be placed using coordinates between $0$~and~$1$ (it employs |axis description cs| automatically). The initial setting is \begin{codeexample}[code only] \pgfplotsset{every axis legend/.style={ cells={anchor=center}, inner xsep=3pt,inner ysep=2pt,nodes={inner sep=2pt,text depth=0.15em}, anchor=north east, shape=rectangle, fill=white,draw=black, at={(0.98,0.98)}}} \end{codeexample} \end{stylekey} \pgfplotsshortstylekey legend style=every axis legend\pgfeov \subsubsection*{Styles for axis lines} \begin{xystylekey}{/pgfplots/every outer \x\ axis line (initially empty)} Installed for every axis line which lies on the outer box. If you want arrow heads, you may also need to check the |separate axis lines| boolean key. \end{xystylekey} \begin{xystylekey}{/pgfplots/every inner \x\ axis line (initially empty)} Installed for every axis line which is drawn using the |center| or |middle| options. \end{xystylekey} \begin{pgfplotsxykeylist}{% axis line style=\marg{key-value-list}, inner axis line style=\marg{key-value-list}, outer axis line style=\marg{key-value-list}, \x\ axis line style=\marg{key-value-list}} These options modify selects parts of the axis line styles. They set |every inner x axis line| and |every outer x axis line| and the respective $y$ variants. \end{pgfplotsxykeylist} \noindent Please refer to section~\ref{pgfplots:page:axislines} on page~\pageref{pgfplots:page:axislines} for details about styles for axis lines. \begin{stylekey}{/pgfplots/every 3d box foreground} Installed for the parts drawn by |3d box=complete|. This affects axis lines, tick lines and grid lines drawn in the \emph{foreground}. The background drawing operations have already been done when this style is evaluated. \end{stylekey} \pgfplotsshortstylekey 3d box foreground style=every 3d box foreground\pgfeov \subsubsection*{Styles for ticks} \begin{stylekey}{/pgfplots/every tick (initially very thin,gray)} Installed for each of the small tick \emph{lines}. \end{stylekey} \pgfplotsshortstylekey tick style=every tick\pgfeov \begin{stylekey}{/pgfplots/every minor tick (initially empty)} Used for each minor tick line, installed after `|every tick|'. \end{stylekey} \pgfplotsshortstylekey minor tick style=every minor tick\pgfeov \begin{stylekey}{/pgfplots/every major tick (initially empty)} Used for each major tick line, installed after `|every tick|'. \end{stylekey} \pgfplotsshortstylekey major tick style=every major tick\pgfeov \begin{stylekey}{/pgfplots/every tick label (initially empty)} Used for each $x$~and~$y$ tick labels. \end{stylekey} \pgfplotsshortxystylekeys tick label style,ticklabel style=every tick label\pgfeov \begin{xystylekey}{/pgfplots/every \x\ tick label (initially empty)} Used for each $x$ (or $y$, respectively) tick label, installed after `|every tick label|'. \end{xystylekey} \pgfplotsshortxystylekeys \x\ tick label style,\x ticklabel style=every \x\ tick label\pgfeov \begin{xystylekey}{/pgfplots/every \x\ tick scale label} Configures placement and display of the nodes containing the order of magnitude of tick labels, see section~\ref{sec:scaled:ticks} for more information about |scaled ticks|. The initial settings are \begin{codeexample}[code only] \pgfplotsset{ every x tick scale label/.style={at={(1,0)},yshift=-2em,left,inner sep=0pt}, every y tick scale label/.style={at={(0,1)},above right,inner sep=0pt,yshift=0.3em}} \end{codeexample} \end{xystylekey} \pgfplotsshortxystylekey \x\ tick scale label style=every \x\ tick scale label\pgfeov \begin{xystylekey}{/pgfplots/every \x\ tick (initially empty)} Installed for tick \emph{lines} on either $x$ or $y$ axis. \end{xystylekey} \pgfplotsshortxystylekey \x\ tick style=every \x\ tick\pgfeov \begin{xystylekey}{/pgfplots/every minor \x\ tick (initially empty)} Installed for minor tick lines on either $x$ or $y$ axis. \end{xystylekey} \pgfplotsshortxystylekey minor \x\ tick style=every minor \x\ tick\pgfeov \begin{xystylekey}{/pgfplots/every major \x\ tick (initially empty)} Installed for major tick lines on either $x$ or $y$ axis. \end{xystylekey} \pgfplotsshortxystylekey major \x\ tick style=every major \x\ tick\pgfeov \begin{xystylekey}{/pgfplots/every extra \x\ tick} Allows to configure the appearance of `|extra x ticks|'. This style is installed before touching the first extra $x$~tick. It is possible to set any option which affects tick or grid line generation. The initial setting is \begin{codeexample}[code only] \pgfplotsset{ every extra x tick/.style={/pgfplots/log identify minor tick positions=true}, every extra y tick/.style={/pgfplots/log identify minor tick positions=true}} \end{codeexample} Useful examples are shown below. \begin{codeexample}[code only] \pgfplotsset{every extra x tick/.append style={grid=major}} \pgfplotsset{every extra x tick/.append style={major tick length=0pt}} \pgfplotsset{every extra x tick/.append style={/pgf/number format=sci subscript}} \end{codeexample} \end{xystylekey} \pgfplotsshortxystylekey extra \x\ tick style=every extra \x\ tick\pgfeov \begin{stylekey}{/pgfplots/extra tick style=\marg{key-value-list}} An abbreviation which appends \meta{key-value-list} to |every extra x tick|, |every extra y tick| and |every extra z tick|. \end{stylekey} \subsubsection*{Styles for grid lines} \begin{stylekey}{/pgfplots/every axis grid (initially thin,black!25)} Used for each grid line. \end{stylekey} \pgfplotsshortstylekey grid style=every axis grid\pgfeov \begin{stylekey}{/pgfplots/every minor grid (initially empty)} Used for each minor grid line, installed after `|every axis grid|'. \end{stylekey} \pgfplotsshortstylekey minor grid style=every minor grid\pgfeov \begin{stylekey}{/pgfplots/every major grid (initially empty)} Likewise, for major grid lines. \end{stylekey} \pgfplotsshortstylekey major grid style=every major grid\pgfeov \begin{xystylekey}{/pgfplots/every axis \x\ grid (initially empty)} Used for each grid line in either $x$ or $y$ direction. \end{xystylekey} \pgfplotsshortxystylekey \x\ grid style=every axis \x\ grid\pgfeov \begin{xystylekey}{/pgfplots/every minor \x\ grid (initially empty)} Used for each minor grid line in either $x$ or $y$ direction. \end{xystylekey} \pgfplotsshortxystylekey minor \x\ grid style=every minor \x\ grid\pgfeov \begin{xystylekey}{/pgfplots/every major \x\ grid (initially empty)} Used for each major grid line in either $x$ or $y$ direction. \end{xystylekey} \pgfplotsshortxystylekey major \x\ grid style=every major \x\ grid\pgfeov \subsubsection*{Styles for error bars} \begin{stylekey}{/pgfplots/every error bar (initially thin)} Installed for every error bar. \end{stylekey} \pgfplotsshortstylekey error bars/error bar style=every error bar\pgfeov \subsubsection{(Re-)Defining Own Styles} \label{sec:styles:own}% Use |\pgfplotsset{|\meta{style name}|/.style=|\marg{key-value-list}|}| to create own styles. If \meta{style name} exists already, it will be replaced. Please note that it is \emph{not} possible to use the \Tikz-command |\tikzstyle|\marg{style name}|=[]| in this context\footnote{This was possible in a previous version and is still supported for backwards compatibility. But in some cases, it may not work as expected.}. \begin{codeexample}[] \pgfplotsset{my personal style/.style= {grid=major,font=\large}} \begin{tikzpicture} \begin{axis}[my personal style] \addplot coordinates {(0,0) (1,1)}; \end{axis} \end{tikzpicture} \end{codeexample}
