\title{
  Plot a Linear Differential Operator Object
}
\description{
  Plot the coefficents of the terms of order 0 through \code{m-1} of an
  object of class \code{Lfd} and length \code{m}.
}
\usage{
\method{plot}{Lfd}(x, axes=NULL, ...)
}
\arguments{
  \item{x}{
    a linear differential operator object to be plotted.
  }
  \item{axes}{
    Either a logical or a list or \code{NULL} passed to \code{plot.fd}.

    \itemize{
      \item{logical}{
	whether axes should be drawn on the plot
      }
      \item{list}{
	a list used to create custom \code{axes} used to create axes via
	\code{do.call(x$axes[[1]], x$axes[-1])}.  The primary example of
	this uses \code{list("axesIntervals", ...)}, e.g., with
	\code{Fourier} bases to create \code{CanadianWeather} plots
      }
    }
  }
  \item{\dots }{
    additional plotting arguments that can be used with function
    \code{plot}
  }
