Graphics, Figures & Tables ⇒ pgfplots | Error Runaway argument \else \expandafter

[Aarran89]

Hi everyone, first post here so please be gentle!

I seem to be having a problem with the creation of a graph using pgfplots in LaTeX. Here is my code:

Code: Select all

\documentclass[traditabstract]{aa}
\usepackage{helvetica}
\usepackage[tbtags]{amsmath}
\usepackage{pgfplots}
\usepackage{graphicx}
\usepackage{ulem}
\usepackage{mathtools}
\usepackage{tikz}
\usepackage{pgfplots}
\newcommand{\tab}{\hspace*{2em}}

\begin{tikzpicture}
    \begin{axis}[ xmin=-16000, xmax=0, ymin=0, ymax=770,
        xlabel=$t_{off}$,
        ylabel=$\chi^2$
    ]
      \addplot plot coordinates {
(-1.4965E+04, 6.90020E+02)
(-1.5965E+04, 6.93870E+02)
(-1.5914E+04, 6.93110E+02)
(-1.5862E+04, 6.92440E+02)
(-1.5811E+04, 6.91870E+02)
(-1.5760E+04, 6.91400E+02)
(-1.5709E+04, 6.91020E+02)
(-1.5657E+04, 6.90730E+02)
(-1.5606E+04, 6.90520E+02)
(-1.5555E+04, 6.91280E+02)
(-1.5503E+04, 6.90870E+02)
(-1.5452E+04, 2.49120E+05
(-1.5401E+04, 7.68160E+02)
(-1.5350E+04, 7.10330E+02)
(-1.5298E+04, 6.98870E+02)
(-1.5247E+04, 6.94550E+02)
(-1.5196E+04, 6.92410E+02)
(-1.5144E+04, 6.91210E+02)
(-1.5093E+04, 6.90520E+02)
(-1.5042E+04, 6.90150E+02)
    };
     \end{axis}
\end{tikzpicture}
\end{document}

I'm using all the correct packages in my preamble and such I think, but when I compile I seem to get this error:

Code: Select all

Runaway argument?
4]\else \expandafter \expandafter \csname pgfflt@2Y1.5401e4]\endcsname 
\ETC.
./Final_Report-draft.tex:173: Paragraph ended before
\pgfflt@readlowlevelfloat
was complete.
<to be read again>
                   \par
l.173

? 

The error is pointing to line 173, which isn't part of my graph, however if I remove all that code then the document compiles as normal.
Has anyone any ideas? I tried supplying definite minimum and maximum xaxis and yaxis values.


Thank you in advance,
Aarran

Hi Aarran,

welcome to the board!

The problem is caused by a missing right parenthesis here:

Code: Select all

(-1.5503E+04, 6.90870E+02)
(-1.5452E+04, 2.49120E+05
(-1.5401E+04, 7.68160E+02)

Just add it.

Some additional advice: for a better chance to get a solution, make it possible for the reader to test and reproduce the problem. You did it nearly good, though

• You used a custom class which is not available for a reader - or what document class is aa in \documentclass[traditabstract]{article}?
• I don't know a package helvetica, perhaps you mean helvet.
• \begin{document} is missing.

So a reader has to "repair" this code to make it compilable. Instead of copying some relevant code, better would be hacking down a real copy, reducing it, or posting code which does produce this error. This code gave just other errors.

Thank you for the reply, I knew it'd be a stupid error! Haha.
Thanks for the hints also, helvetica is a custom .sty, whereas aa.cls is a template from Astronomy and Astrophysics, which is the style I'm trying to emulate with this report. \begin{document} was something I forgot to copy in when I posted this message, sorry about that
Thanks again for your swift reply, I've fixed it all now, and I'll be sure to keep everything in mind for the inevitable next time I post!
