# Can \draw .. controls .. be found in pgfplots?

I just want to use something like .. controls .. in an addplot command. Unfortunately, the option "smooth" does not produce the image I desire. I haven't found it in the manual so far. The reason I'm not uusing tikz directly, is because i want to use the legend of pgfplots.

Any other ideas? If necessary I will post a MWE.

Edit: It is not really a MWE but i hope it helps. I couldn't use draw with controls in axis (even though I expressed the coordinates in the axis cs). The red "graph" is only shows how i want the blue line to be bend

\documentclass{minimal}
\usepackage{tikz,pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}
{(0,0)(0.2,0)(0.8,1)(1,1)};
\end{axis}
\end{tikzpicture}

\begin{tikzpicture}[scale=5]
\draw[red] (0,0) .. controls (0.2,0) and (0.8,1)
.. (1,1);
\end{tikzpicture}
\end{document}

• A MWE is a very good idea. – Thorsten Donig Feb 9 '14 at 9:55
• Maybe worth a look: Why should the minimal class be avoided?. – Tobi Feb 9 '14 at 11:09
• Thanks, the minimal class seems to cause lots of problems here, without it, I find the correct graph, though still obtaining some errors, which are probably due to a wrong coordinate system. (axis cs:0,0) seems to cause problems. – Quickbeam2k1 Feb 9 '14 at 11:23

You can access the coordinate system, which is used to plot functions by axis cs as in

\draw (axis cs:0,0) -- (axis cs:1,1);


For more on accessing axis coordinates in graphical elements, see section 4.17.1 on page 290 of the pgfplots manual.
