[Tex/LaTex] Center flow chart horizontally

diagramshorizontal alignmentpstricks

I have the following flow chart but it appears uncentered. How can I center it?

\documentclass{article}
\usepackage{pstricks}
\usepackage{pst-node}
\usepackage{pst-blur}
\pagestyle{empty}

\begin{document}
\begin{center}
\psframebox[linearc=5mm,cornersize=absolute]{%
\begin{psmatrix}[rowsep=0.6,colsep=0.5]
\psovalbox[fillstyle=solid]{Begin} &
\psframebox[]{ChIP-seq} &
\psframebox[]{align to genome} &
\psdblframebox[framearc=.4,fillstyle=solid]{Find peaks} &
\psdblframebox[framearc=.4,fillstyle=solid]{Thresholding} &
\psdblframebox[framearc=.4,fillstyle=solid]{Analysis} &
\psframebox[]{stop} 
\ncline{->}{1,1}{1,2}
\ncline{->}{1,2}{1,3}
\ncline{->}{1,3}{1,4}
\ncline{->}{1,4}{1,5}
\ncline{->}{1,5}{1,6}
\ncline{->}{1,6}{1,7}
\end{psmatrix}}
\end{center}

\end{document}

Best Answer

As frabjous already mentioned, the image is just too big and either image or margins require adjustment.

But there's trick how you can center oversized images: use \makebox. This way even your wide image gets properly centered:

\noindent\makebox[\textwidth]{%
\psframebox[linearc=5mm,cornersize=absolute]{%
\begin{psmatrix}
  ...
\end{psmatrix}
}}

[Tex/LaTex] How to center horizontally but not vertically

One single character would make a difference: try \begin{figure}[ht!] instead. By adding this option the picture would float to the top of the page.

However, because the picture doesn't need to float across page borders and should be just at the top, you don't need a figure environment. Instead, you could use the \captionof command of the caption package, which you're already loading. Here's a small example based on your code:

\documentclass{article}
\usepackage[margin=5pt,nohead]{geometry}
\usepackage{tikz}
\usepackage{caption}
\begin{document}
\begin{centering}
  \begin{tikzpicture}[scale=(3/10)]
    \draw[help lines] (0,0) grid (670mm,700mm);
  \end{tikzpicture}
  \captionof{figure}{some caption here}
\end{centering}
\end{document}

Adding \centering after \begin{table} will center the table:

Notes:

The showframe package was used to add the margins so that the centering effect can be seen.
Using centering is preferred over the center environment as the environment adds additional vertical space.

Code:

\documentclass{article}
\usepackage{showframe}

\begin{document}
\begin{table}[H]
\centering
\caption{Robustness checks---Organised events}
\begin{tabular}{lc} \hline
VARIABLES & Org. event \\ \hline
 &  \\
Price shock & -0.212 \\
 & (0.177) \\
 &  \\
Observations & 2,226 \\
Number of city\_group & 37 \\
R-squared & -0.021 \\ \hline
\multicolumn{2}{c}{ Robust standard errors in parentheses} \\
\multicolumn{2}{c}{ *** p$<$0.01, ** p$<$0.05, * p$<$0.1} \\
\end{tabular}
\end{table}
