Page Layout ⇒ First page is blank, figure is shifted to right

[skylla]

Hi, I am somewhat new to LaTeX. I am using TeXworks with the pgf and tikz packages and the automata library to draw an FST. I use the document class of article and layout of landscape. Otherwise, all I am doing is drawing a Finite State Transducer. The first page is blank, and the FST starts almost horizontally center of the page and vertically below center of the page. My code is below. I would like the FST to be on the first page, and more centered, any help?

Code: Select all

\documentclass[landscape]{article}
\pagestyle{empty}
\usepackage[rgb]{xcolor}
\usepackage{pgf}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[->,shorten >=1pt,node distance=5cm,auto,thick,bend angle=45, minimum size=5mm, >=stealth]
\usetikzlibrary{automata}

\node[state] (q_1) [right of=q_0] {$q_1$};
\node[state] (q_2) [below right of=q_1] {$q_2$};
\node[state] (q_3) [above right of=q_2] {$q_3$};
\node[state] (q_4) [above of=q_3] {$q_4$};
\node[state] (q_5) [above of=q_2] {$q_5$};
\node[state] (q_8) [left of=q_2,fill=orange,text=blue] {$q_8$};
\node[state] (q_6) [below left of=q_2,fill=cyan,text=blue] {$q_6$};
\node[state] (q_7) [right of=q_6,fill=red,text=blue] {$q_7$};
\node[state] (q_9) [above right of=q_0,fill=magenta,text=blue] {$q_9$};

Hi skylla,

welcome to the board!
That's a good code example. Btw. the forum provides a code environment for better readability, I will insert the code tags into your post to show it.

Your TikZ picture is too big to fit to the page, you should get a warning "Overfull \vbox". You could make it smaller or change the margins, like

Code: Select all

\usepackage[top=7mm]{geometry}

Thanks, that worked, you're awesome! One question though, I was not getting a warning and the graphic did fit on a page, it was just displaying on the second page and shifted funny. Any particular reason my code did that? Changing the top margin as you suggested placed the picture nicely centered on the first page.

[Stefan Kottwitz]

The standard margins were just so big that the figure didn't fit to the page, and what's not fitting will be moved to the next page. The margins are not visible, causing the impression the picture might fit.
