Very often I search a special library of TikZ. At the moment there is no package which loads every library.

Is there a list of all available libraries with a short introduction (2-3 sentences)?

Maybe we can collect them here

  • 36
    Part IV of the PGF manual is all the libraries; the TOC gives their names, and each section starts with a short introduction. – Ryan Reich Jan 28 '12 at 19:56

    @RyanReich Why don't you add that as an answer? (If Marco still wants to collect libraries here, this question should probably be CW.) – doncherry Jan 29 '12 at 9:10

    What about third party libraries? It would actually be more useful to list those. – Faheem Mitha Jan 29 '12 at 12:43

    @doncherry: I don't think it would be a very good answer, and however correct, he must have known that already. Also, as an answer it would not be the first, whereas it is now the top comment :) – Ryan Reich Jan 29 '12 at 17:23
  • I totally do not understand the purpose of this list that just mimics the very good PGF documentation. Apparently, other members consider it as very useful, given the number of favorite links, which is a mystery to me. Am I overlooking something? – Daniel May 25 '12 at 19:07

Summary

Here's the list of libraries, and a brief summary of the purpose of each (any code supplied is for LaTeX and/or Plain TeX, not ConTeXt):

  • Arrow tip library with \usetikzlibrary{arrows.meta} (\usetikzlibrary{arrows} is deprecated). See details below.
  • Automata Drawing Library, accessed by \usetikzlibrary{automata}, and is used for drawing "finite state automata and Turing Machines". To draw these graphs, each node, its name and relative position is defined, as well as the types of path between each.
  • Background Library, accessed by \usetikzlibrary{backgrounds}, and "defines background for pictures". To use this in a Tikzpicture, an option is passed, e.g. \begin{tikzpicture}[show background rectangle], with a background rectangle style defined before the picture. (e.g. \tikzset{background rectangle/.style={<define background rectangle style here>}}
  • Calc library, accessed through \usetikzlibrary{calc} to make complex coordinate calculations. See details below.
  • Calendar Library, accessed through \usetikzlibrary{calendar}. This library is used to display calendars (I guess it's a Ronseal thing). You define a calendar as \calendar[display options and date options](Name (optional)).
  • Chain library to align nodes o chains. See details below.
  • Decorations libraries to decorate paths. See details below.
  • Entity Relationship Diagram Library, accessed by \usetikzlibrary{er}, as in the automata drawing library, each node is defined, as is each edge between each node, as well as any attributes. As a note of warning, underlining should be used for attributes, but this is not used as it is both ugly and difficult to implement. Italics are used instead.
  • Intersection library, accessed through \usetikzlibrary{intersections}, to calculate intersections of paths. See details below.
  • Mind map library, accessed through \usetikzlibrary{mindmap}. See details below.
  • Matrix Library, accessed through \usetikzlibrary{matrix}. Matrices are defined in the same way as in maths mode, however, each item in the matrix as assigned a value as a node, starting from 1. Each node can then be identified and manipulated. Delimiters can also be selected in the matrix options and can be "any delimiter that is acceptable to TeX’s \left command".
  • Paper folding library \usetikzlibrary{folding}. See details below.
  • Pattern Library \usetikzlibrary{patterns}. This package "defines patterns for filling areas". In the documentation, each pattern is named and an example given.
  • Petri-Net Library. This is used to draw Petri Nets, as used for mathematical modelling. As with other similar flowchart style diagrams, each node and edge is defined, as well as their style and position. Tokens can also be embedded within nodes, by treating them as children and child nodes.
  • Plot handler Library, accessed through \usetikzlibrary{plothandlers}. TikZ loads this library automatically. Each point is defined (as a node) for the plot and the each point has a curve placed
    • Plot Mark Library, accessed through \usetikzlibrary{plotmarks} is used to define additional styles for plots as used above. Each point is defined as \pgfuseplotmark{Plot description}.
  • Shape library, used to define shapes other than rectangle, circle and co-ordinate. Accessed through either \usetikzlibrary{shapes} or \usetikzlibrary{shapes.shape type}. The following additional types are available: geometric shapes, either named shapes (star, diamond, etc.) or polygons of specified side numbers; symbol shapes, e.g. "forbidden sign" as used in No Smoking signs; "multipart" shapes, with "multiple (text) parts"; and finally, "misc" shapes which "do not fit in the previous categories", such as strike-through crosses. See details below.
  • Snake library, as accessed through \usetikzlibrary{snakes} and can be best described as curved lines, and are used either between nodes or as a border to a shape , or as independent shapes.
  • To Path library, accessed through \usetikzlibrary{topaths}. This library is used to define paths between two points, and is loaded automatically. Additionally, it can take the form of curved lines between two shapes or as a loop back to a node.
  • Tree library, accessed through \usetikzlibrary{trees}. Each point on the tree is defined as a node, with children, and each child can have its own children. The tree's direction can also be specified, as well as the angle at which children emerge, however, when left to its own devices, the results are acceptable.

Sources: Anything in inverted commas has been lifted from the tikzpgfmanual, as well as the calendar sample.

    How about making a CW answer for each library including an example image. So one can easily add new librarys. I would make an example and start to port your list to separated answers if it’s ok with you. – Tobi Jan 29 '12 at 13:04

    it looks like double, thin uses single lines, but this is due to the shrunk image. If you run the code given you'll see that it's really double lines. – Tom Bombadil Jan 29 '12 at 17:29

Chains Library

Accessed by \usetikzlibrary{chains}

Description

Chains are sequences of nodes that are arranged in a row or a column and that are, typically, connected by edges. More generally, they can be used to position nodes of a branching network in a systematic manner. For the positioning of nodes in rows and columns you can also use matrices (see Section 17 of pgfmanual.pdf) but chains can also be used to describe the connections between nodes that have already been connected using, say, matrices. Thus, it often makes sense to use matrices for the positioning of elements and chains to describe the connections.

Example with Chains

\documentclass{standalone}

\usepackage{tikz}
\usetikzlibrary{shapes,% for the rectangle
                chains,% provides the chains
                scopes}% allows to replace \begin{scope} \end{scope} with {}

\begin{document}

    bottom color=red!50!black!20, % and something else at the bottom
    font=\itshape
  },
  terminal/.style={
    rectangle,minimum size=6mm,rounded corners=3mm,

  { [start branch=plus]
    \node (plus) [terminal,on chain=going above right] {+};
  }
  { [start branch=minus]
    \node (minus) [terminal,on chain=going below right] {-};
  }
  \node [on chain, nonterminal, join=with chain/plus-end, join=with chain/minus-end] {unsigned integer};

Chains with Labels

Some times one needs to add labes to the edges created by the chains library (it happened to me before). Although it is not supported natively by the library, you can do it by tweaking the library.

An example is:

\documentclass{standalone}

\usepackage{tikz}
\usetikzlibrary{shapes,% for the rectangle
                chains,% provides the chains
                scopes}% allows to replace \begin{scope} \end{scope} with {}

I created a PDF with all the libraries and a short definition from the pfdmanual.

enter image description here

You can find the PDF here table-library

It's a first version and I have not reread or corrected and I think the order is not fine. The last libraries about graphs need luatex.

    Your pdf link is dead. Could you update it, please. Thank you. – Hotschke May 27 '14 at 8:09
  • I added the PDF to the my site. With pgf 3.0 I need to update now the document. – Alain Matthes May 31 '14 at 9:32
  • Thank you very much. Highly appreciated, the pgf/tikz documentation is very large but unhandy. – Hotschke May 31 '14 at 17:38

Miscelaneous contributions to TikZ (total of 70)

Maybe this is not the proper place to put this answer but I think it may help someone.

Here is a link that contains several contributions made to TikZ, some of them have to be loaded as packages and some can be loaded commonly as libraries through \usetikzlibrary but are not documented at the TikZ/PGF manual, instead they have their own documentation like packages.

I'll list some of the packages/libraries and a very short description of what it does

  • knots (tikz library): provide environment to draw knots easily computing intersection and automatically Splitting the path into several paths one over another.
  • hobbys (tikz library): an implementation of John Hobby's algorithm to produce a smooth curve through a given set of points, it allows further customization of the curve than the normal plot operator and its result without any customization is significantly better than plot.
  • forest: offers highly improved tree drawing mechanism that than of just TikZ, should definetely be considered before drawing a tree with TikZ.
  • tikz-cd: provides support through predefined macros and default settings for drawing commutative diagrams.
  • prooftree: provides support for drawing prooftrees, the package is focused on math prooftrees used to teach math.
  • pgf-spectra: uses easy syntax to draw the spectrum of elements (currently 99 available)
  • bloques: provides set of macros to ease the drawing of block diagrams used in control theory (engineering).
  • circuitikz: used to draw electronic circuits.
  • tikzscale: provides some interface between tikzpictures and \includegraphics offering scaling methods for tikzpictures.

I have counted 65 contributions in the former link, the above cited are not the best nor special in any way, It's just the ones I've came across with.


Isolated contributions:

I've also found in user's @Qrrbrbirlbel (how do you say that?) 5 neet libraries (yep they're loaded with \usetikzlibrary), unfortunately without manuals and not available through CTAN (hopefully they'll get there) but can be downloaded in Qrrbrbirlbel's GitHub account, the below is a near copy paste of his "About me" profile text:

  • node-families

    The node-families library has been developed in response to “Dependent node size” where the OP asks for automatic re-sizing of related nodes so that they have the same minimum size. Use the following keys to assign a node to a specific family of nodes that shall have the same dimensions. This works on a per-picture basis and uses the .aux file so you will need at least two compilations.

    • Minimum Width=<family>;
    • Minimum Height=<family>;
    • Text Height=<family>;
    • Text Width=<family>.
  • paths.ortho (code file here and lib file here)

    This library introduces path operators like the horizontal-vertical ones TikZ naturally has (|- and -|) but more advanced, like |-| and -|-. This answer and this one too contain more info on the library.

  • paths.rectangle

    The paths.rectangle library provides two similar timers (the functions that place nodes along paths) for the rectangle path operator. Usually when doing \draw (0,0) rectangle node[pos=x]{A} (1,1) the node A will be placed in a position along the line connecting the two coordinates, with paths.rectangle, x can assume values greater than 1 (up to 2) which represent the actual rectangle path, not the line between the coordinates, as better explained in this answer.

  • patterns.images

    This library allows shapes to be filled with image patterns, much useful to create images with textures. It's explained in this answer.

  • positioning-plus

    This one offers a way of positioning one node in respect with several others, providing also capability of making the node as large as the set of nodes it spans. Aside from that it has more positioning options than that of the original positioning library, since there is no manual the information has to be gathered from TeX.SX search engine (this link auto searches with the proper filters)

Decoration libraries

Accessed by \usetikzlibrary{decorations.<name of decoration library>}

Description
As the name says, these libraries decorate a path. Sometimes the path is even substituted with a different path.

Every decoration library is stated below. Use Ctrl + F (Windows) to get to the library you need.


Path morphing decorations

Accessed by \usetikzlibrary{decorations.pathmorphing}

Description [from the TikZ manual]
A path morphing decoration "morphs" or "deforms" the to-be-decorated path. This means that what used to be a straight line might afterwards be a snaking curve and have bumps.

Example

\documentclass[tikz,margin=1]{standalone}
\usetikzlibrary{decorations.pathmorphing}
\def\y{0}
\newcommand\decorated[1]{
    \tikzset{decoration=#1}
    \draw[thin,red] (0,\y) to[bend left] (1,\y);
    \filldraw[decorate,fill=yellow!60,very thick] (0,\y) to[bend left] (1,\y)
        node[right,font=\ttfamily] {#1};
    \let\auxy\y
    \pgfmathsetmacro\y{\auxy+1}
}
\begin{document}
\begin{tikzpicture}[y=-1cm,x=3cm]
\decorated{lineto}
\decorated{straight zigzag}
\decorated{random steps}
\decorated{saw}
\decorated{zigzag}
% We are not able to use our command here :(
\tikzset{decoration=bent}
\draw[thin,red] (0,\y) -- (1,\y);
\filldraw[decorate,fill=yellow!60,very thick] (0,\y) -- (1,\y)
    node[right,font=\ttfamily] {bent};
\let\auxy\y
\pgfmathsetmacro\y{\auxy+1}
% %
\decorated{bumps}
\decorated{coil}
\decorated{curveto}
\decorated{snake}
\end{tikzpicture}
\end{document}

Path replacing decorations

Accessed by \usetikzlibrary{decorations.pathreplacing}

Description [from the TikZ manual]
This library defines decorations that replace the to-be-decorated path by another path. Unlike morphing decorations, the replaced path might be quite different, for instance a straight line might be replaced by a set of circles.

Example

  • Most decorations

    \documentclass[tikz,margin=1]{standalone}
    \usetikzlibrary{decorations.pathreplacing}
    \def\y{0}
    \newcommand\decorated[1]{
        \tikzset{decoration=#1}
        \draw[thin,red] (0,\y) to[bend left] (1,\y);
        \draw[decorate,very thick] (0,\y) to[bend left] (1,\y)
            node[right,font=\ttfamily] {#1};
        \let\auxy\y
        \pgfmathsetmacro\y{\auxy+1}
    }
    \begin{document}
    \begin{tikzpicture}[y=-1cm,x=3cm]
    \decorated{border}
    % We are not able to use our command here :(
    \tikzset{decoration=brace}
    \draw[thin,red] (0,\y) -- (1,\y);
    \draw[decorate,very thick] (0,\y) -- (1,\y)
        node[right,font=\ttfamily] {brace};
    \let\auxy\y
    \pgfmathsetmacro\y{\auxy+3}
    % %
    \decorated{expanding waves}
    \let\auxy\y
    \pgfmathsetmacro\y{\auxy+1.5}
    \decorated{ticks}
    \decorated{waves}
    \end{tikzpicture}
    \end{document}
