Graphics, Figures & Tables ⇒ Creating a Diagram

[steFON]

Hello, I am new here.

I'd like to get help with this diagram. How can I create it with LaTeX?

Thanks.

How do your own efforts look like? As it stands now, your request sounds like "Do this for me". We would appreciate questions that sound more like "Can you help me on with my code?". So, please start a serious approach on your own and ask for help when running into trouble.

You can try packages like PGF/TikZ (Example gallery) or PSTricks (Example gallery) to draw the diagram. The respective manuals have the details. You may also look at the "Similar Topics" at the bottom of this page for possible solutions (only when logged in).


Best regards and welcome to the board

Hi stefon,

welcome to the forum!

There are several packages which could be used for such diagrams, such as TikZ, tikz-cd, PSTricks, xy-pic and amscd. TikZ is very modern und currently perhaps the most popular.

Have a look at this commutative diagram example, or at TikZ diagrams in the example gallery.
Perhaps try it and tell us, when you would have further questions about this.

Sorry, but I am really new in LaTeX

I tried to do it with this:

Code: Select all

\begin{diagram}[heads=LaTeX]
                   &                 &\textrm{výraz?}  & \\
                   &\ldTo^{označuje} &&\rdTo^{vyjadřuje}\\
\textrm{denotát}   &\rTo^{dole}       &\textrm{smysl}
\end{diagram}

But there is no option to do "left-right" arrow.

Which package are you using? Try to post a complete small example, so we can see. It's unclear what you mean with this diagram environment.

I use this packages:

Code: Select all

\usepackage[small,nohug,heads=vee]{diagrams}
\diagramstyle[labelstyle=\scriptstyle]

But I only copy it from one document about diagrams.

[localghost]

It seems that this is not an official package. Furthermore is appears very limited.

With the already suggested PGF/TikZ it is quite straightforward with nice arrows. The output is attached.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\usetikzlibrary{positioning}

\begin{document}
  \begin{tikzpicture}[
    >=stealth,
    node distance=3cm
  ]
    \node (A) at (0,0) {A};
    \node[below left=of A] (B) {B};
    \node[below right=of A] (C) {C};

    \path[<->] (A) edge node[midway,above left] {D} (B)
               (A) edge node[midway,above right] {E} (C)
               (B) edge node[midway,below] {F} (C);
  \end{tikzpicture}
\end{document}

For details please refer to the package manual.

Thank you localghost, but when I implmented your code to my .tex it draw only letters, no arrows I do not know where is problem.

Look at the PS or PDF output, not at DVI.

[steFON]

I use WinEdt, and there is option to create pdf from dvi, so I choose it, and nothing happened. But, when I push "PDF TeXify" it create pdf file. THANK YOU VERY MUCH!!! Really nice diagram
