PSTricks: Remove trailing zeros in axis labels

Consider the following example:

\documentclass{article}

\usepackage{pst-plot}

\begin{document}

\psset{xunit = 2}
\begin{pspicture}(3,1)
\psaxes[Dx = 0.5]{->}(3,1)
\end{pspicture}

\end{document}


Is it possible to get 1 and 2 instead of 1.0 and 2.0 (as with 0) as axis labels?

If you make a question in LaTeX-Community then you should not repost it in TeX.StackExchange, or vice verse because cross-sites posting is not allowed as far as I know. – kiss my armpit Jan 11 '14 at 20:51
@StiffJokes As long as I make a comment about posting it both places and post an answer, given on one side, on the other, too, I don't see the problem. – Svend Tveskæg Jan 12 '14 at 9:53
@SvendTveskæg: from a physicians view, it should not be written as 1 and 2 – Herbert Jan 12 '14 at 16:21
@Herbert I know. :) – Svend Tveskæg Jan 12 '14 at 16:22
@CodeMocker Cross-Posts are allowed on LaTeX-Community.org, the poster should just include a link, so everybody knows. Can save time. Svend did it perfectly, and as I know a cross-post here is fine as well, just not within different StackExchange sites since they topics separate and focused. – Stefan Kottwitz Jan 12 '14 at 20:45

Here a solution with some internal justification:

\documentclass{article}
\usepackage{pst-plot}
\makeatletter
\def\@LabelComma#1.#2.#3\@nil{%
\def\pst@tempA{#1}%
\ifx\pst@tempA\@empty\the\@zero\else#1\fi% the integer part
\def\pst@tempA{#2}
\ifx\pst@tempA\@empty
\@writeDecimals{}%
\else%
\ifnum#2=0\relax\else%
\@writeDecimals{#2}%
\fi%
\fi%
}
\makeatother

\begin{document}
\psset{xunit = 2}
\begin{pspicture}(3,1)
\psaxes[Dx = 0.5]{->}(3,1)
\end{pspicture}
\end{document}

A recommended solution with fp.

\documentclass[pstricks,border=24pt,12pt]{standalone}

\usepackage{pst-plot}
\usepackage[nomessages]{fp}

\begin{document}

\psset{xunit = 2}
\begin{pspicture}(3,1)
\psaxes[ticks=none,labels=none]{->}(3,1)
\multido{\r=.0+.5}{6}{\psxTick(\r){\FPeval\temp{clip(\r)}\temp}}
\end{pspicture}

\end{document}

Does this mean it is not possible to modify the labels of the axes directly? – clemens Jan 12 '14 at 10:15
@cgnieder Good point. What you are asking for is exactly what I would like. – Svend Tveskæg Jan 12 '14 at 10:16
@cgnieder: I don't know the internal details of PSTricks. Herbert might be able to answer your question. :-) – kiss my armpit Jan 12 '14 at 10:17
What would be the output with the other step value: \multido{\r=.0+.4}{6}? – g.kov Jan 12 '14 at 11:34
@g.kov: Then use the more accurate one \n instead of \r, \multido{\n=.0+.4}{6}{\psxTick(\n){\FPeval\temp{clip(\n)}\temp}}. – kiss my armpit Jan 12 '14 at 16:32
