Graphics, Figures & Tables ⇒ using command in gnuplottex

[nico]

Hi,

i want to use a command in a gnuplot-environment. I know, that the content is set to the terminal, but is there any way to do this?

Please see the example:

Code: Select all

\documentclass[10pt,a4paper]{scrartcl}
\usepackage{amsmath}
\usepackage{gnuplottex}

\begin{document}
\newcommand{\pltSetB}{set xlabel "t [d]"
    set ylabel "c [kg/m^3]"
    set autoscale}
    
\begin{figure}[H]
    \begin{gnuplot}[terminal=pdf]
    \pltSetB
    plot sin(x)
    \end{gnuplot}
\end{figure}
\end{document}

The gnuplot environment of the gnuplottex package changes category codes of characters similar to a verbatim environment to submit a proper script to Gnuplot. Therefore control sequences within this environment won't work.

Consider to generate your plots either with pgfplots (based on pgf/tikZ) or pst-plot (based on pstricks).

Hello Thorsten,

first of all: Thanks a lot. I decided to use pgfplots. In my eyes it is much more convenient for my purpose than gnuplot.

I got it working with this approach:

Code: Select all

\documentclass[10,a4paper]{scrartcl}
\usepackage{pgfplots}

\begin{document}

\newcommand{\setWidthCoal}{\textwidth}
\newcommand{\setXLabelCoal}{Tage}

\begin{figure}
\begin{tikzpicture}
\begin{axis}[width=\setWidthCoal,xlabel=\setXLabelCoal]
	\addplot[color=blue,mark=*] coordinates {(1,8)(2,16)(3,32)(4,64)(5,128)(6,256)(7,512)};
\end{axis}
\end{tikzpicture}
\end{figure}
\end{document}

It is ok, but it would be much better, if i could use it like that:

Code: Select all

\documentclass[10,a4paper]{scrartcl}
\usepackage{pgfplots}

\begin{document}

\newcommand{\setAxisCoal}{width=\textwidth,xlabel=Tage}

\begin{figure}
\begin{tikzpicture}
\begin{axis}[\setAxisCoal]
	\addplot[color=blue,mark=*] coordinates {(1,8)(2,16)(3,32)(4,64)(5,128)(6,256)(7,512)};
\end{axis}
\end{tikzpicture}
\end{figure}
\end{document}

But i get "! Missing \endcsname inserted." with this. Is there a way to fix this?

Use the \pgfplotsset command for global settings as described in the pgfplots manual.

Well...it's not really gnuplottex anymore, but i'm fine with this solution. So maybe it helps other ones too. Thank you, guys!!

Code: Select all

\documentclass[10,a4paper]{scrartcl}

\usepackage{pgfplots}

\pgfplotsset{
B/.style={xlabel=Tage,ylabel=Konzentration der Kohle,legend entries={1,2}}   % Define a own style
}

\begin{document}

\begin{figure}
\begin{tikzpicture}
\begin{axis}
	\pgfplotsset{B};     % Set the defined style
    \addplot coordinates {(1,8)(2,16)(3,32)(4,64)(5,128)(6,256)(7,512)};
\end{axis}
\end{tikzpicture}
\end{figure}

\end{document}
