# float row figure box - two lines in caption

I am trying to get the caption on two lines with this command but using \\ does not work. If anyone know how to do this it would be helpful

\begin{figure}
\begin{floatrow}
\ffigbox{%
\caption{Incentive Tune: $\theta_{1} = 0.0167$, $\theta_{2} = 0.008$ }
\includegraphics[scale= .35]{chapters/Chapter09/ch9_3.eps}%
}{%
}
\ffigbox{%
\caption{Incentive Tune: $\theta_{1} = 0.019$, $\theta_{2} = 0.01$ }
\includegraphics[scale=.35]{chapters/Chapter09/ch9_4.eps}%
}{%
}
\end{floatrow}
\end{figure}

• Welcome to TeX.SX! Please, make your code into a minimal example, from \documentclass to \end{document}, showing the necessary packages for getting the output (we can deal with EPS files quite easily, so they're not important). – egreg Mar 15 '14 at 17:42

Load the caption package:

\documentclass{article}
\usepackage{floatrow}
\usepackage{graphicx}
\usepackage{caption}

\begin{document}

\begin{figure}
\begin{floatrow}
\ffigbox
{\includegraphics[scale= .35]{example-image-a}}
{\caption{Incentive Tune: \\ $\theta_{1} = 0.0167$, \\ $\theta_{2} = 0.008$}%
}
\ffigbox
{\includegraphics[scale=.35]{example-image-b}}
{\caption{Incentive Tune: \\ $\theta_{1} = 0.019$, \\ $\theta_{2} = 0.01$}%
}
\end{floatrow}
\end{figure}

\end{document}
