[Tex/LaTex] minipage alignment with tikzpicture

beamerminipagetikz-pgf

I want to have one minipage containing a tikzpicture and on its right another minipage with a block, and tried with:

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,chains}
\usetikzlibrary{positioning}
\begin{document}
...
\begin{minipage}{0.75\textwidth}  
\begin{tikzpicture}  
\tikzset{base/.style={draw, on chain, on grid, align=center, minimum height=4ex},
 norm/.style={->, draw},
}
% -------------------------------------------------
    \node [base,text width=10cm] (one) {text in box};
    \end{tikzpicture}
    \end{minipage}%
    \begin{minipage}[b]{0.2\textwidth}
      \begin{block}{\huge Legend}
       ...
      \end{block}
    \end{minipage}

However the two minipages become very distant (horizontally), as if the first minipage is aligned to the left margin and the second minipage is aligned to the right margin. Could anyone suggest what to do?

Best Answer

The snippet contains:

\end{minipage}%
\begin{minipage}...

Thus, there is no horizontal space between them. The second minipage can be moved to the right by:

\end{minipage}\hfill
\begin{minipage}...

and putting both minipages in a box:

\noindent
\hbox to \linewidth{%
  \begin{minipage}...
  \end{minipage}%
  \hfill
  \begin{minipage}...
  \end{minipage}%
}\par

Or as last line of a paragraph:

\begin{minipage}...
\end{minipage}%
\hfill
\begin{minipage}...
\end{minipage}%
{\setlength{\parfillskip}{0pt}\par}

With a full MWE, it would have been easier to provide the best code.

[Tex/LaTex] \footnotemark and \footnotetext in minipage

Footnotes within minipage environments are printed with small letters. The definition in latex.ltx is

\def\thempfootnote{{\itshape\@alph\c@mpfootnote}}

You could redefine it. A quick way would be:

\let\thempfootnote\thefootnote

Afterwards the footnote symbols within a minipage will be an arabic number as well.

[Tex/LaTex] Rotate a node but not its content: the case of the ellipse decoration

The source of the difficulty is that ellipses are constructed in a particular way in TikZ. They are paths that start from the x-axis and proceed counter-clockwise around their centre. The vast majority of the time, the exact parametrisation doesn't matter. You appear to have found the one situation where it does!

In the actual question, you only want to be able to mirror the ellipse, and so draw it starting from the negative x-axis (the title of the question suggests a more flexible approach). That's actually not too hard since we can exploit the symmetry of the ellipse. The key is to provide it with a negative x-radius, since then it will start from the negative x-axis (and proceed clockwise, but we could correct for that by negating the y-radius as well). To do this, we interrupt the call from the node shape to the drawing command and flip the sign of the x-radius. The simplest way to do this is to redefine the \pgfpathellipse macro to do the negation and then call the original macro. The following code does this.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations,shapes,decorations.markings}
\makeatletter
\let\origpgfpathellipse=\pgfpathellipse
\def\revpgfpathellipse#1#2#3{%
  #2%
  \pgf@xa=-\pgf@x
  \origpgfpathellipse{#1}{\pgfqpoint{\pgf@xa}{0pt}}{#3}}
\makeatother

\tikzset{
  reversed ellipse/.style={
    ellipse,
    reverse the ellipse%
  },
  reverse the ellipse/.code={
    \let\pgfpathellipse=\revpgfpathellipse
  }
}
\begin{document}
\begin{tikzpicture}
\node[ellipse,
  draw,
  postaction={
    decorate,
    decoration={
      markings,
      mark=at position 1 with {
        \arrow[line width=5pt,blue]{>}
      }
    }
  }
] at (0,0) {hello world};

\node[reversed ellipse,
  draw,
  postaction={
    decorate,
    decoration={
      markings,
      mark=at position 1 with {
        \arrow[line width=5pt,blue]{>}
      }
    }
  }
] at (0,-2) {hello world};
\end{tikzpicture}

\end{document}

Here's the result:

rotated ellipse

(the arrow got clipped, but you can see where it lies)
