5 TikZ & PGF(plots) TikZ ist kein Zeichenprogramm Portable Graphics Format / pretty, good, functional Usable with L A TEX, TEX, ConTEXt

6 TikZ Program your graphics Advantages: quick creation of simple graphics, precise positioning, macros, superior typography Disadvantages: steep learning curve, no WYSIWYG, compilation times

7 PGFPLOTS Draw plots and labeled axes easily Linear plots, logplots, semi-logplots 2D and 3D

8 Part I TikZ

9 TikZ Coordinates Many different coordinate systems Always in round brackets Absolute or relative Cartesian, Polar, Barycentric, Perpendicular, user-defined,... (3d.north) (polar.west) polar (60:3) 1 (2,1.5) 2 +(0,-1) 4 3 +(0,1) ++(1,0) (2-3) (0,0,2) 3d

10 TikZ Paths Basic entity of drawing Consist of parts Closed or open curves

11 TikZ Nodes Text placed at coordinate Simple and complex shapes Anchors for precise positioning \node is shorthand for \path node [draw, circle] [fill=red] \node[draw] There is NO CLOUD, just [shape= cloud] other people s computers [draw=red, fill=blue, text=white, font=\tiny, thick, rounded corners=4mm]

12 TikZ Nodes: Labels and Pins Add nodes to existing nodes Can be called multiple times per node above left πr pins 60 east 135 above left 60 πr labels east 135 below right

13 TikZ Nodes: Matrices Mostly treated like nodes Similar to tabular environment Consist of rows of cells Each cell contains a cell picture cell1; & cell2; \\ column sep row sep 1a 1b 1c 2a 2b 2c 3a 3b 3c

14 TikZ Trees Visualize hierarchical structures Customizable growth functions

15 TikZ Coordinate transformations Rotate, translate, scale, slant scale=2 rotate=60 yslant=-1 shift=(-1,-1)

16 Libraries Arrow tip Automata drawing Background Calc Calendar Chains Circuits (logical) Circuits (electrical engineering) Decoration ER diagram drawing Externalization Fading Fitting Fixed point arithmetic Lindenmayer system drawing Matrix Mindmap drawing Paper folding diagrams Pattern Petri-net drawing Plot handler Plot mark Profiler Shadings Shadow Shape Spy SVG-path To path Through Tree Turtle graphics

17 Part II PGFPLOTS

18 PGFPLOTS Plots Plots contained in axis environment \addplot Data inline or from file

19 PGFPLOTS Plots: \addplot coordinates, file, table, expression \addplot, \addplot+ const plot, sharp plot, smooth, x/ybar (interval), x/ycomb, only marks, scatter, mesh \addplot3, \addplot3+ sharp plot, smooth, scatter, only marks, mesh, surf expr: sin(x) coords file table

20 PGFPLOTS Plots: Automatic style cycling Plot styles from a predefined list Used for plot lines and legend entries x 0 x 1 x 2 x 3 x 4 x

21 PGFPLOTS Plots: styles solid, (densely/loosely) dotted, (densely/loosely) dashed thin, ultra thin, very thin, semithick, thick, very thick, ultra thick red, green, blue, cyan, magenta, yellow, black, gray, white, darkgray, lightgray, brown, lime, olive, orange, pink, purple, teal, violet mark=*, x, +, -,, o, asterisk, star, oplus(*), otimes(*), square(*), triangle(*), diamond(*), pentagon(*), cube(*), text, user defined y x

22 PGFPLOTS Plots: descriptions title x/ylabel title legend 4 legend ticklabel style axis x/y line ylabel xlabel (axis cs:3,-2)

23 PGFPLOTS Number formatting Pretty-print numbers \pgfmathprintnumber [...]{...} fixed, sci, std, frac,... std: fixed: 12,304, fixed, zerofill: 12,304, sci: sci, sci e: 1.23e+7 sci, zerofill: frac: frac, frac whole=false:

24 PGFPLOTS Plots: Tick options x/y/ztick= \empty, data, coordinate list {0,1,3.5,2 e1}, {0,...,5}, {0,2,...,5}, {9,...,3.5}

25 PGFPLOTS Plots: Grid options x/y/zminorgrids x/y/zmajorgrids grid=major/minor/both minor major both
