\title{Plotting of dynamic time warp results}
\description{
Plot a DTW results for visual inspection.
}
\usage{
dtwPlotThreeWay(d,xts=NULL,yts=NULL,type.align="p",type.ts="l",
margin=4, inner.margin=0.2, title.margin=1.5,
xlab="Query index",ylab="Template index",main="Timeseries alignment",
... )
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{d}{ an alignment result, object of class \code{dtw}}
\item{xts}{ query vector }
\item{yts}{ template vector }
\item{xlab}{ label for the query axis}
\item{ylab}{label for the template axis}
\item{main}{main title}
\item{type.align}{line style for alignment path plot}
\item{type.ts}{line style for timeseries plot}
\item{margin}{outer figure margin }
\item{inner.margin}{inner figure margin }
\item{title.margin}{space on the top of figure}
\item{...}{additional arguments, passed to plotting functions}
}
\details{
Display the query and template time series and their
alignment, arranged so that alignment can be
visually inspected.
Only single-variate time series are supported, and
they must be passed to the \code{x} and \code{y}
arguments (query and template are not stored
in the \code{dtw} object).

\note{
The value axis for the template time series grows rightwards.
This may be counter-intuitive.
}
\examples{
## A noisy sine wave as query
## A cosine is for template; sin and cos are offset by 25 samples
idx<-seq(0,6.28,len=100);
query<-sin(idx)+runif(100)/10;
template<-cos(idx)
dtw(query,template,keep=TRUE)->alignment;
## Beware of the template's y axis, may be confusing
## Equivalent to plot(alignment,xts=query,yts=template,type="three");
dtwPlotThreeWay(alignment,xts=query,yts=template);
