//@Module LINEPROPERTIES Line Series Object Properties
//@@Section HANDLE
//@@Usage
//Below is a summary of the properties for a line series.
//\begin{itemize}
// \item @|color| - @|colorspec| - The color that is used to
// draw the line.
// \item @|children| - Not used.
// \item @|displayname| - The name of this line series as it
// appears in a legend.
// \item @|linestyle| - @|{'-','--',':','-.','none'}| - The style of the line.
// \item @|linewidth| - @|scalar| - The width of the line.
// \item @|marker| - @|{'+','o','*','.','x','square','s','diamond','d','^','v','>','<'}| -
// The marker for data points on the line. Some of these are redundant, as @|'square'|
// @|'s'| are synonyms, and @|'diamond'| and @|'d'| are also synonyms.
// \item @|markeredgecolor| - @|colorspec| - The color used to draw the marker. For some
// of the markers (circle, square, etc.) there are two colors used to draw the marker.
// This property controls the edge color (which for unfilled markers) is the primary
// color of the marker.
// \item @|markerfacecolor| - @|colorspec| - The color used to fill the marker. For some
// of the markers (circle, square, etc.) there are two colors used to fill the marker.
// \item @|markersize| - @|scalar| - Control the size of the marker. Defaults to 6, which
// is effectively the radius (in pixels) of the markers.
// \item @|parent| - @|handle| - The axis that contains this object.
// \item @|tag| - @|string| - A string that can be used to tag the object.
// \item @|type| - @|string| - Returns the string @|'line'|.
// \item @|visible| - @|{'on','off'}| - Controls visibility of the the line.
// \item @|xdata| - @|vector| - Vector of x coordinates of points on the line. Must be
// the same size as the @|ydata| and @|zdata| vectors.
// \item @|ydata| - @|vector| - Vector of y coordinates of points on the line. Must be
// the same size as the @|xdata| and @|zdata| vectors.
// \item @|zdata| - @|vector| - Vector of z coordinates of points on the line. Must be
// the same size as the @|xdata| and @|ydata| vectors.
// \item @|xdatamode| - @|{'auto','manual'}| - When set to @|'auto'| FreeMat will autogenerate
// the x coordinates for the points on the line. These values will be @|1,..,N| where
// @|N| is the number of points in the line.
// \item @|userdata| - @|array| - Available to store any variable you
// want in the handle object.
//\end{itemize}
