Graphics, Figures & Tables ⇒ Missing Axes Labels in Plot from Matlab

[Andreasdreas]

I have a problem including a graph I have made in Matlab in my LaTeX code. I can get the graph by running the LaTeX code, but the labels of the axis and the scale of the axis is not taken with. Here is what I have done.

My matlab-script is like so:

Code: Select all

XYdata=xlsread('TEK0.xls');
voltage=XYdata(:,2);
time=XYdata(:,1);

figure;
plot(time,voltage,'r', 'linewidth',2);

xlabel('time in seconds');
ylabel('voltage in volts');

print -deps epsFig

When i run this script i get this graph:

Graph produced by Matlab-code

To get this graph into my LaTeX document i insert the following in the LaTeX code:

Code: Select all

\begin{figure}[H]
\centering
\includegraphics{Kapitler/Forsog/Data/Rectify/data_fra_29_11/epsFig}
\caption{caption}
\end{figure}

And the result is this:

Graph produced by LaTeX -code

I have loaded the graphicx package in my preamble and everything is in the same folder.

I would like to know how I can get the axis labels and scale into my LaTeX figure, if it is not too complicated. I hope you can help me.

Perhaps the EPS file is flawed for some reason. Try to correct it with the »eps2eps« tool from Ghostscript.

If there are no concerns from your side, could you upload the file »TEKO.xls« to the forum server? Probably you need to put it into an archive (*.zip, *.rar or *.tar.gz). There are some LaTeX alternatives for plotting datasets.


Best regards and welcome to the board

Thanks for the respond.

1. My teammates can when they run the LaTeX script see the graph with scales and labels on the axis. So its only on my computer the problem is. (We share the files with Dropbox).
2. Is it possible to get color on the graphs in the PDF created by LaTeX?
3. I have installed Ghostscript 9.06 for Windows (64bit) (this fits for my PC), but how do I exactly use the eps2eps tool? I have tried searching for it on my PC and opened what came up, then a command window opens and closes again, and the nothing more seems to happen.

The file "TEK0.xls" is attached.

It is not really necessary to get the number and labels on the axis when I run the code on my computer, but it could be nice to solve it though

[…] My teammates can when they run the LaTeX script see the graph with scales and labels on the axis. So its only on my computer the problem is. (We share the files with Dropbox). […]

Are there any significant differences in the working environments (TeX system, operating system, …) that may explain this?

I should have asked for the EPS file because this question can only be answered if we have the EPS file present and can test its behaviour when included in a document. So, please attach the EPS file to your next post (no need to put it into an archive since the server accepts EPS).

The eps2eps tool is for the command line and therefore needs some parameters to do its work. Perhaps its better to open the command line window explicitly for a better look at its output. The following line should be enough.

Code: Select all

eps2eps input.eps output.eps

That should give the file "output.eps" in the same folder as "input.eps".

In my last reply I mentioned a LaTeX solution. I took your *.xls file and exported it to *.csv (comma separated values, CSV). This is the format that the LaTeX package pgfplots accepts for plotting datasets. In form of code it looks like this.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{pgfplots}

\pgfplotsset{
  compat=newest,
  xlabel near ticks,
  ylabel near ticks
}

\begin{document}
  \begin{tikzpicture}[font=\scriptsize]
    \begin{axis}[
      scaled ticks=false,
      xmin=-0.015,
      xmax=0.015,
      xlabel={Time / s},
      xticklabel style={/pgf/number format/.cd,fixed,precision=3},
      ymin=-0.5,
      ymax=0.4,
      ylabel={Voltage / V},
%      ytick={-0.5,-0.4,...,0.5},
      yticklabel style={/pgf/number format/.cd,fixed,precision=1},
    ]
      \addplot[red] table {TEK0.csv};
    \end{axis}
  \end{tikzpicture}
\end{document}

The output is attached. For details see the (quite comprehensive) package manual.

I have tried doing the same thing as you. Putting the following in my document:

Code: Select all

\begin{tikzpicture}[font=\scriptsize]
    \begin{axis}[
      scaled ticks=false,
     xmin=-0.015,
      xmax=0.015,
      xlabel={Time / s},
     xticklabel style={/pgf/number format/.cd,fixed,precision=3},
     ymin=-0.5,
      ymax=0.4,
     ylabel={Voltage / V},
%      ytick={-0.5,-0.4,...,0.5},
      yticklabel style={/pgf/number format/.cd,fixed,precision=1},
    ]
      \addplot[red] table {Kapitler/Forsog/Data/Rectify/data_fra_11_12/TEK0.csv};
  \end{axis}
 \end{tikzpicture}
 \end{document}

And the following to my preamble:

Code: Select all

\usepackage[T1]{fontenc}
\usepackage{pgfplots}%Ting til grafer (sat ind december 2012)
\pgfplotsset{
  compat=newest,
  xlabel near ticks,
  ylabel near ticks
} %Ting til grafer (sat ind december 2012)

The document class is
\documentclass[a4paper,11pt,fleqn,twoside,openright] I don't know if this makes a difference.

The CSV file is attached. When i save the CSv file i choose the punktuation: Westeurope (Windows-1252/WinLatin1).

The following errors comes up:

Is the package manual what comes up when I follow this link http://ctan.org/tex-archive/graphics/pg ... b/pgfplots (which I find when I follow your link). I admit that I haven't really read it through, I find all this pretty confusing. Do I have to download something to use the packages?

[localghost]

You have done some mistakes when exporting your XLS spreadsheet to CSV. See the attached CSV file in my last reply for comparison.

• Cell content should not be enclosed by quotes.
• You need to tell the package which column separator you use.
• The decimal separator has be a period instead of a comma.
• The additional text has to be erased.

The formats for data files accepted by pgfplots are given in the package manual. The code you copied should be working also in your actual document.

As the only problem with your EPS figure I recognize that it does not show any color. And when I include it into a document I see all axes scales and labels. Nevertheless there seems to be something wrong with it. But a remote diagnosis is not possible because we don't know what you actually did to produce it. In the file (viewed with a text editor) I spotted that it uses the CMYK color space. Perhaps that's the culprit here.

The package is correctly installed on your system. Otherwise you wouldn't receive the error message. So you don't have to worry in this regard.
