\keyword{hplot}{zoomChromosome}
\begin{Description}\relax
Plot splitting the screen into two.  The top windows displays the
entire chromosome, whilst the bottom plots a selected region.  The plot
is interactive allowing the user to click twice on a chromosome in the upper
plot and have it the region between the two clicks displayed below.
\end{Description}
\begin{Usage}
\begin{verbatim}
zoomChromosome(..., array = 1, chrom.to.plot, colors = NULL, chrominfo =
chrominfo.Mb, ylim = c(-2, 2))
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{...}] Objects of type \code{\LinkA{MAList}{MAList}} or
\code{\LinkA{SegList}{SegList}}
\item[\code{array}] Specify which array should be plotted.
\item[\code{chrom.to.plot}] Which chromosome should be plotted
\item[\code{colors}] Vector specify the colors for each of the SegLists
\item[\code{chrominfo}] chromosomal information associated with the
mapping of the data.
\item[\code{ylim}] Specify the limits of the y-axis
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
If colors is unspecified then all SegLists passed to this function will
be plotted in blue.  Since this makes it quite hard to tell which is
which it is highly recommened to specify the colors vector if more
than one object is being passe to this function.
