\section{COLORBAR Add Colorbar to Current Plot}

\subsection{Usage}

There are a number of syntaxes for the \verb|colorbar| command.  The first
takes no arguments, and adds a vertical colorbar to the right of the current
axes.
\begin{verbatim}
  colorbar
\end{verbatim}
You can also pass properties to the newly created axes object using
the second syntax for colorbar
\begin{verbatim}
  colorbar(properties...)
\end{verbatim}
