Two tikZ pictures side by side

[joshmccraney]

Hi PF!

I have been trying to put two tikZ pictures next to each other but I can't figure out how to do it. I've used the \begin{minipage} command, which worked well, but was unable to generate a caption. Any ideas?

Yea, I clicked on the first several google suggestions, but notice the one that you reference has the minipage, and for some reason I can't seem to add a single caption for both pictures underneath. Any suggestions?

Can you post some code?

Sure, and I actually just found a way to do it using the subfigure package. Below is a working example:

\documentclass{article}
\usepackage{tikz}
\usepackage{subcaption} 

\begin{document}
\begin{figure}
    \begin{subfigure}[b]{0.32\textwidth}
        \centering
        \resizebox{\linewidth}{!}{
            \begin{tikzpicture}
                \draw (2,2) circle (3cm);
            \end{tikzpicture}
        }
        \caption{Subfigure A}
        \label{fig:subfig8}
    \end{subfigure}
    \begin{subfigure}[b]{0.32\textwidth}
    \centering
        \resizebox{\linewidth}{!}{
            \begin{tikzpicture}
                \draw (2,2) circle (3cm);
            \end{tikzpicture}
        }
        \caption{Subfigure B}  
        \label{fig:subfig9}
    \end{subfigure}
    \begin{subfigure}[b]{0.32\textwidth}
        \centering
        \resizebox{\linewidth}{!}{
            \begin{tikzpicture}
                \draw (2,2) circle (3cm);
            \end{tikzpicture}
        }
        \caption{Subfigure C}
        \label{fig:subfig10}
    \end{subfigure}
\caption{big caption} 
\label{fig:subfig1.a.4}
\end{figure}

\end{document}

Actually, while this is not the same question, perhaps you could help? For this line of code

\draw[domain=0.1:1,samples=100,color=blue,variable=\x] plot (\x,{(\x)^(1/2)});

tikZ is plotting $y=x^{-1/2}$ and when I change the code to

\draw[domain=0.1:1,samples=100,color=blue,variable=\x] plot (\x,{1/(\x)^(1/2)});

tikZ is plotting $y=x^{1/2}$. Any idea as to why this is?
