# Tikzpicture in a two column way using a one column .cls template

I'm using a .cls IEEEtran from IEEE available here http://www.ieee.org/conferences_events/conferences/publishing/templates.html; and all document is in two columns.

I'm ploting using pgfplots a graphic but it is using just one column and i want that it occupies all the two columns.

An example code of the plot is:

\documentclass[conference]{IEEEtran}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{booktabs}
\usepackage{amssymb}
\usepackage{array}
\usepackage{subfigure}
\usepackage[english]{babel}
\usepackage{float}
\usepackage{multirow}
\usepackage{graphicx}
\usepackage{icomma}
\usepackage{tikz}
\usepackage{pgfplots}

\newcounter{groupcount}
\pgfplotsset{
draw group line/.style n args={5}{
after end axis/.append code={
\setcounter{groupcount}{0}
\pgfplotstableforeachcolumnelement{#1}\of\datatable\as\cell{%
\def\temp{#2}
\ifx\temp\cell
\ifnum\thegroupcount=0
\stepcounter{groupcount}
\pgfplotstablegetelem{\pgfplotstablerow}{[index]0}\of\datatable
\coordinate [yshift=#4] (startgroup) at (axis cs:\pgfplotsretval,0);
\else
\pgfplotstablegetelem{\pgfplotstablerow}{[index]0}\of\datatable
\coordinate [yshift=#4] (endgroup) at (axis cs:\pgfplotsretval,0);
\fi
\else
\ifnum\thegroupcount=1
\setcounter{groupcount}{0}
\draw [

\fi
\fi
}
\ifnum\thegroupcount=1
\setcounter{groupcount}{0}
\draw [
shorten >=-#5,
shorten <=-#5
] (startgroup) -- node [anchor=north] {#3} (endgroup);
\fi
}
}

I tried to use:

But it didn't work. Anyone may help me with that?

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). –  texenthusiast Mar 1 '13 at 23:34
Could you turn your code snippet into a complete compilable minimal example document (starting from \documentclass)? –  Jake Mar 2 '13 at 5:16
No one can answer this question unless you tell us which document class it is. Publishers do weird things in their .cls files, but some have commands or environments for full-width content, e.g. widetext in APS revtex. –  Alex Mar 2 '13 at 10:42
Jake, Alex thanks about the comments, i've edited my question with an example, i hope taht you undertand now. –  João Mar 3 '13 at 22:29

You are using [b!] specifier and you don't have any text so weird things are bound to happen. Also please truncate the example next time to isolate the issue, you don't use many of the packages here.

You need to use the starred version of the figure environment otherwise it forces the figure to be on one of columns for which location specifiers make sense. Otherwise I recommend leaving it alone. You can read an excellent summary in How to influence the position of float environments like figure and table in LaTeX? to get more info about the starred version.
