The representation places the vertices on horizontal lines corresponding to the <a title="generates the filtration of a poset" href="_filtration.html">filtration</a> of the poset. The only displayed edges are the <a title="computes the minimal list of generating relations of a poset" href="_covering__Relations.html">coveringRelations</a> which are oriented so that lower vertices less than higher vertices.</p> <p>The method attempts to display labels in a sane way, if they are not suppressed by the <span class="tt">SuppressLabels</span> option. Note that the <span class="tt">SuppressLabels</span> option's default value can be set in the "~/.Macaulay2/init-Posets.m2" file.</p> <p>Further, sometimes the vertices of the poset line up in unfortunate ways that causes edges to touch other vertices. Using the <span class="tt">Jitter</span> option can relieve this by adding a small random horizontal shift to each vertex.</p> </div> <table class="examples"> <tr> <td> <pre><code class="language-macaulay2">i1 : texPoset booleanLattice 2 o1 = \begin{tikzpicture}[scale=1, vertices/.style={draw, fill=black, circle, inner sep=0pt}] \node [vertices] (0) at (-0+0,0){}; \node [vertices] (1) at (-.75+0,1.33333){}; \node [vertices] (2) at (-.75+1.5,1.33333){}; \node [vertices] (3) at (-0+0,2.66667){}; \foreach \to/\from in {0/1, 2/3, 0/2, 1/3} \draw [-] (\to)--(\from); \end{tikzpicture}</code></pre> </td> </tr> <tr> <td> <pre><code class="language-macaulay2">i2 : texPoset(booleanLattice 2, Jitter => true) o2 = \begin{tikzpicture}[scale=1, vertices/.style={draw, fill=black, circle, inner sep=0pt}] \node [vertices] (0) at (-0+.267814,0){}; \node [vertices] (1) at (-.75+.202018,1.33333){}; \node [vertices] (2) at (-.75+1.58819,1.33333){}; \node [vertices] (3) at (-0+.189883,2.66667){}; \foreach \to/\from in {0/1, 2/3, 0/2, 1/3} \draw [-] (\to)--(\from); \end{tikzpicture}</code></pre> </td> </tr> </table> </div> <div> <h2>Caveat</h2> <div> <p>Calling texPoset via the command <a title="convert to $\\TeX$ format" href="../../Macaulay2Doc/html/_tex.html">tex</a> expects that no options are given.</p> </div> </div> <div> <h2>See also</h2> <ul> <li><span><a title="computes the minimal list of generating relations of a poset" href="_covering__Relations.html">coveringRelations</a> -- computes the minimal list of generating relations of a poset</span></li> <li><span><a title="generates a PDF representation of a poset and attempts to display it" href="_display__Poset.html">displayPoset</a> -- generates a PDF representation of a poset and attempts to display it</span></li> <li><span><a title="generates the filtration of a poset" href="_filtration.html">filtration</a> -- generates the filtration of a poset</span></li> <li><span><a title="writes a LaTeX file with a TikZ-representation of a poset" href="_output__Tex__Poset.html">outputTexPoset</a> -- writes a LaTeX file with a TikZ-representation of a poset</span></li> </ul> </div> <div> <div class="waystouse"> <h2>Ways to use <span class="tt">texPoset</span>:</h2> <ul> <li><kbd>texPoset(Poset)</kbd></li> </ul> </div> <div class="waystouse"> <h2>For the programmer</h2> <p>The object <a title="generates a string containing a TikZ-figure of a poset" href="_tex__Poset.html">texPoset</a> is <span>a <a title="a type of method function" href="../../Macaulay2Doc/html/___Method__Function__With__Options.html">method function with options</a></span>.</p> </div> <hr> <div class="waystouse"> <p>The source of this document is in <span class="tt">Posets.m2:4182:0</span>.</p> </div> </div> </div> </body> </html>
