4.2The Axis Environments

There is an axis environment for linear scaling, two for semi-logarithmic scaling and one for double-logarithmic scaling.

  • \begin{tikzpicture}[(math image)options of tikz(math image)]

  • (math image)environment contents(math image)

  • \end{tikzpicture}

    • This is the graphics environment of TikZ. It produces a single picture and encloses also every axis.

    Instead of using the environment version, there is also a shortcut command

    \tikz{(math image)picture content(math image)}

    which can be used alternatively.

  • \begin{axis}[(math image)options(math image)]

  • (math image)environment contents(math image)

  • \end{axis}

    • The axis environment for normal plots with linear axis scaling.

    The ‘every linear axis’ style key can be modified with

    \pgfplotsset{every linear axis/.append style={...}}

    to install styles specifically for linear axes. These styles can contain both TikZ and pgfplots options.

  • \begin{semilogxaxis}[(math image)options(math image)]

  • (math image)environment contents(math image)

  • \end{semilogxaxis}

    • The axis environment for logarithmic scaling of \(x\) and normal scaling of \(y\). Use

    \pgfplotsset{every semilogx axis/.append style={...}}

    to install styles specifically for the case with xmode=log, ymode=normal.

    The logarithmic scaling means to apply the natural logarithm (base \(e\)) to each \(x\)-coordinate. Furthermore, ticks will be typeset as \(10^{\text {\meta {exponent}}}\), see Section 6.1.7 for more details.

  • \begin{semilogyaxis}[(math image)options(math image)]

  • (math image)environment contents(math image)

  • \end{semilogyaxis}

    • The axis environment for normal scaling of \(x\) and logarithmic scaling of \(y\),

    The style ‘every semilogy axis’ will be installed for each such plot.

    The same remarks as for semilogxaxis apply here as well.

  • \begin{loglogaxis}[(math image)options(math image)]

  • (math image)environment contents(math image)

  • \end{loglogaxis}

    • The axis environment for logarithmic scaling of both, \(x\)- and \(y\)-axes. As for the other axis possibilities, there is a style ‘every loglog axis’ which is installed at the environment’s beginning.

    The same remarks as for semilogxaxis apply here as well.

They are all equivalent to

\begin{axis}[ xmode=log|normal, ymode=log|normal] ... \end{axis}

with properly set variables ‘xmode’ and ‘ymode’ (see below).
