# sidewaysfigure in two column document span whole page

Hello I would like a sideways figure to span a whole page in a two column artikel. The problem is that the solutions I have found either fit a none rotated figure to a two column page or only rotates the image in a onecloumn document.

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{natbib}
\usepackage{rotating}
\usepackage{tikz}

%Awesome twocolumn text....

\onecolumn
\begin{sidewaysfigure*}[h]
\centering
\begin{tikzpicture}[scale=4]
\includegraphics[width=\textwidth]  {/home/sebastiano/Documents/Data/plots/3binNoCorrected.png}
\end{tikzpicture}
\caption{All light curves from all available datasets}
\label{allLightCurves}
\end{sidewaysfigure*}


But this still remembers the twocolumn even if they are turned off.

• Welcome to TeX.SX! Why do you use tikzpicture for \includegraphics? – TeXnician Feb 8 '17 at 10:53
• Thanks for having me ;) I just found this as working way to produce a side ways image? – Sebastiano1991 Feb 8 '17 at 10:55
• Why don't you just use \includegraphics? – TeXnician Feb 8 '17 at 10:57
• How stupid ! Yes commenting out the \tikzpicture did the trick! I thought it was needed for the sidewaysfigure... must have missunderstood that other stack... thanks! – Sebastiano1991 Feb 8 '17 at 10:59
• The tikzpicture is unnecessary in your example, but is not the main problem. There are cases where a tikzpicture is quite usefull, e.g to add some decoration to the picture. But then you should put the graphic in a node: \node{\includegraphics[width=\textwidth] {example-image-a}}; so that the tikzpicture has the correct size. – Ulrike Fischer Feb 8 '17 at 11:32

A solution for your problem is to just remove the unnecessary tikzpicture.
