Graphics, Figures & Tables ⇒ pst-plot | "\savedata" with "\newcommand"

[mamboreina79]

Hello, I just joined today and this is my first post, I couldn't find anything here or on the web about this problem and I don't know enough about LaTeX to figure out how to fix it.

I'm using pst-plot package to make a figure that shows several plots with the same style. Like this:

3 beautiful plots with same style :)

I want to define my own pspicture with a command before the begin{document} tag, so that I can just enclose the plotting information inside a tag in the body, thus separating style from content.

This is the smallest minimal example code I was able to write that will show the first of the plots:

Code: Select all

\documentclass[12pt]{article} 
\usepackage[english]{babel}
\usepackage{graphicx,color}
\usepackage{pstricks,pst-plot,pstricks-add}

% The size of my figure:
\newcommand*{\ancho}{125.22mm}
\newcommand*{\alto} {270.26mm}
\special{papersize=\ancho,\alto}

% Free canvas: (basically zero everything)
\setlength{\hoffset}{-1in}	\setlength{\voffset}{-1in}
\setlength{\marginparsep}{0cm}	\setlength{\marginparwidth}{0cm}
\setlength{\oddsidemargin}{0cm}	\setlength{\evensidemargin}{0cm} \setlength{\marginparpush}{0cm}
\setlength{\topmargin}{0cm}	\setlength{\footskip}{0cm}
\setlength{\headsep}{0cm}	\setlength{\headheight}{0cm}
\setlength{\textwidth} {\ancho}	\setlength{\textheight} {\alto}
\setlength{\paperwidth}{\ancho}	\setlength{\paperheight}{\alto}

\begin{document}
  \pagestyle{empty} % No page numbering 'cos it's a figure
  \centering
  \psset{xunit=0.01748mm, yunit=1209.21mm, 
         plotstyle=bar, barwidth=2pt, fillstyle=solid, fillcolor=gray
         }
  \begin{pspicture}(-1350,-0.008)(5810,0.0665)
    \psaxes[Dx=1000,Dy=0.02] (0,0)(5735,0.065)
    \savedata{\mydata}[482,0.06]
    \listplot{\mydata}
  \end{pspicture}
\end{document}

And what I want to do is something like this:

Code: Select all

\documentclass[12pt]{article} 
\usepackage[english]{babel}
\usepackage{graphicx,color}
\usepackage{pstricks,pst-plot,pstricks-add}

% The size of my figure:
\newcommand*{\ancho}{125.22mm}
\newcommand*{\alto} {270.26mm}
\special{papersize=\ancho,\alto}

% Free canvas: (basically zero everything)
\setlength{\hoffset}{-1in}	\setlength{\voffset}{-1in}
\setlength{\marginparsep}{0cm}	\setlength{\marginparwidth}{0cm}
\setlength{\oddsidemargin}{0cm}	\setlength{\evensidemargin}{0cm} \setlength{\marginparpush}{0cm}
\setlength{\topmargin}{0cm}	\setlength{\footskip}{0cm}
\setlength{\headsep}{0cm}	\setlength{\headheight}{0cm}
\setlength{\textwidth} {\ancho}	\setlength{\textheight} {\alto}
\setlength{\paperwidth}{\ancho}	\setlength{\paperheight}{\alto}

% ----------------- MY PSPICTURE ------------------------
\newcommand{\myfig}[1]{
  \psset{xunit=0.01748mm, yunit=1209.21mm, 
         plotstyle=bar, barwidth=2pt, fillstyle=solid, fillcolor=gray
         }
  \begin{pspicture}(-1350,-0.008)(5810,0.0665)
    \psaxes[Dx=1000,Dy=0.02] (0,0)(5735,0.065)
    #1     % --------> MY PLOTTING STUFF
  \end{pspicture}
}

\begin{document}
  \pagestyle{empty} % No page numbering 'cos it's a figure
  \centering
  \myfig{ % MY CALL INSIDE THE DOCUMENT
    \savedata{\mydata}[482,0.06]
    \listplot{\mydata}
  }

% ANOTHER PLOT WITH THE SAME STYLE
% \myfig{ ...STUFF... }
% ANOTHER PLOT WITH THE SAME STYLE
% \myfig{ ...STUFF... }
% ETC.
\end{document}

I'm compiling like this:

Code: Select all

latex myfig
dvips myfig.dvi -o myfig.ps
ps2pdf myfig.ps myfig.pdf

on an Ubuntu 10.11 and using gedit for the writing.

The first example, using pspicture inside the document, works fine.
The second example, calling an external pspicture, doesn't. I get a plot with nothing inside it, and an error in the last step when trying to convert to pdf. It starts with "Error: /undefined in 482,0.06", which is the point I am passing to savedata to make the plot.

Do you have any idea of why is it happening? Is there a better way to do this? Thanks in advance

I have been playing a bit more with this and I think there is no problem with passing "\data" to an external function. I defined a small new command "\myplot" that works like "\myfig", but substitutes the "\listplot" command.

So basically I used the same code of the second example and added two lines before the "\begin{document}":

Code: Select all

% ...
% ...Same header as before...
% ...

% --- TWO NEW LINES: ----
\newcommand{\myplot}[2]{
  \listplot[fillcolor=gray,#1]{#2}
}

    \begin{document}
      \pagestyle{empty} % No page numbering 'cos it's a figure
      \centering

% --- USING THE OLD AND NEW COMMANDS ----
\myfig % <----------------------- OLD
  { 
  \readdata{\data}{data.dat}
  \myplot{}{\data} % <----------- NEW
  }

    % ANOTHER PLOT WITH THE SAME STYLE
    % \myfig{ ...STUFF... }
    % ANOTHER PLOT WITH THE SAME STYLE
    % \myfig{ ...STUFF... }
    % ETC.
  \end{document}

The content of data.dat is 482 0.06.
This code works fine and reproduces the same results as the first example of my post. So the problem is something with the "\savedata" command... and not with passing "\data"... but I still dunno what

Why can't I pass data read with "\savedata" to the "\myfig" command ??
I would appreciate any help on this.
