[Tex/LaTex] New TikZ arrowhead

tikz-arrowstikz-pgf

I'm looking how to use currarrow as a new arrowhead in tikz.

Especially it's of the same size of latex or stealth and way smaller than triangle 45.

Any idea how to make it?

For now I use node[currarrow, sloped, allow upside down, pos=1] {} which is not really convenient…

A quick conceptual definition with hard coded values, you can combine it with Luigi's goodies. It won't work with different line widths etc. since I didn't do any right/left extend calculation.

I took the currarrow definition from circutikz library. It doesn't look too different from the scaled triangle 45. I would recommend using Luigi's definitions and modifiying them if necessary.

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows}
\makeatletter
\pgfarrowsdeclare{mycurrarrow}{mycurrarrow}{
\pgfarrowsleftextend{-5\pgflinewidth}
\pgfarrowsrightextend{5\pgflinewidth}
}
{
            \newlength\pgf@my@length
            \pgf@my@length = 1cm
            \divide \pgf@my@length by 16
            \pgfpathmoveto{\pgfpoint{-.7\pgf@my@length}{0pt}}
            \pgfpathlineto{\pgfpoint{-.7\pgf@my@length}{-.8\pgf@my@length}}
            \pgfpathlineto{\pgfpoint{1\pgf@my@length}{0pt}}
            \pgfpathlineto{\pgfpoint{-.7\pgf@my@length}{.8\pgf@my@length}}
            \pgfpathlineto{\pgfpoint{-.7\pgf@my@length}{0pt}}           
            \pgfusepathqfillstroke
}
\makeatother
\begin{document}
\begin{tikzpicture}
    \draw[mycurrarrow-mycurrarrow,blue] (0,0) -- (2,1);
    \draw[latex-latex,shift={(0mm,3mm)}] (0,0) -- (2,1);
    \draw[triangle 45-triangle 45,shift={(0mm,-3mm)},red] (0,0) -- (2,1);
\end{tikzpicture}
\end{document}

I don't get why you don't post five lines of code(four being documentclass and begin/end document and circutikz package)for an example instead of describing the arrow with screenshot from the manual.

You can use near start and near end. I think this is what you're describing:

\documentclass[border=2pt]{standalone}
\usepackage{amsmath}
\usepackage{pxfonts}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}[auto]
\node (A) at (0,0) {A};
\node (B) at (2,4) {B};
\draw[font=\tiny] (A) to node[near end] {first line should be smaller and close to B} 
                         node[near start] {second line should be smaller and close to A} (B);
\end{tikzpicture}

\end{document}

To get even closer, you can use very near start.

[Tex/LaTex] Plot alignment using groupplot in pgfplots

Thanks to Jake's suggestion, a significant compression of my original solution is possible (since I don't know a thing about tikz). Also, a new version of stackengine should hit the streets this weekend. The syntax I used here will work in both old and new versions. You can control the inter-plot separation, if desired (i.e., normal hspacing will work between the top two plots, and an optional length argument to \stackunder will define the vertical gap).

\documentclass{standalone}
\usepackage{stackengine}
\usepackage{tikz,pgfplots}
    \usepgfplotslibrary{groupplots}
\begin{document}
\stackunder{%
  \begin{tikzpicture}
    \begin{axis}[width=4cm, height=4cm] \addplot coordinates{%
      (0,0) (1,2) (2,1)}; \end{axis}
  \end{tikzpicture}
  \begin{tikzpicture}
    \begin{axis}[width=4cm, height=4cm] \addplot coordinates{%
      (0,0) (1,2) (2,1)}; \end{axis}
  \end{tikzpicture}
}{%
  \begin{tikzpicture}
    \begin{axis}[width=4cm, height=4cm] \addplot coordinates{%
      (0,0) (1,2) (2,1)}; \end{axis}
  \end{tikzpicture}
}
\end{document}
