\label{Authoring_Dynamic_Plot_Curve_Data}

The \textbf{data} tag is used to specify the values plotted in the 
\textbf{gnuplot} \ref{Authoring_Dynamic_Plot_Gnuplot} tag.
The \textbf{data} tag is only used in the \textbf{Curve} 
\ref{Authoring_Dynamic_Plot_Curve} tag.

The data must be either a perl array, \textt{@X}, or a comma seperated list,
such as ``0.5,0.9,1.5, 2.4'' (without quotes).  'NaN' is a valid value.  

The function and number \textbf{data} tags required varies based on the 
line style \ref{Authoring_Dynamic_Plot_Linestyle} chosen for the
curve.  In all cases the first \textbf{data} tag will hold the ``X'' values
and the second will hold the ``Y'' values.

All of the data sets in the \textbf{data} tag must have the same number of
elements.
