    1: \label{Authoring_Dynamic_Plot_Curve}
    2: 
    3: The \textbf{curve} tag is where you set the data to be plotted by gnuplot.
    4: 
    5: The following parameters may be present in the \textbf{curve} tag and allow
    6: access to most of the formatting parameters for a curve in gnuplot.
    7: 
    8: 
    9: \begin{itemize}
   10: 
   11: \item color
   12: 
   13: The color of the curve on the plot. See ``Selecting Colors'' section  
   14: \ref{Authoring_Dynamic_Plot_Color_Selection}.
   15: 
   16: 
   17: \item name
   18: 
   19: If a key is present, the name of the curve will appear with a sample of its
   20: line type.
   21: 
   22: \item linestyle
   23: 
   24: See ``Line Styles'' section \ref{Authoring_Dynamic_Plot_Linestyle} for
   25: more information about the available line styles and their data requirements.
   26: 
   27: \item linetype
   28: 
   29: The type of line.  Current options include `solid' and `dashed'.  At this time, all dashed lines draw with line width of `1' in web output.  This parameter may not apply to all linestyles.
   30: 
   31: \item linewidth
   32: 
   33: The thickness of the line drawn by plotting engine.  This parameter may not apply to all linestyles.
   34: 
   35: \item pointtype
   36: 
   37: This parameter may not apply to all linestyles.
   38:  
   39: \item pointsize
   40: 
   41: This parameter may not apply to all linestyles.  The size of the points, in
   42: pixels, present on the line.  Some point types are not affected by this
   43: parameter.
   44: 
   45: \item  limit 
   46: 
   47: This parameter controls the pont to fill for fillled curves.
   48: 
   49: \item arrowhead
   50: 
   51: For vector plots, controls where in the vector the arrow head(s) appear
   52: 
   53: \item arrowstyle
   54: 
   55: For vector plots controls the fill style of the arrow.
   56: 
   57: \item arrowlength
   58: 
   59: For vector plots determines the distance between the vector line end and the tip
   60: of the arrow.
   61: 
   62: \item arrowangle
   63: 
   64: For vector plots, determines the angle the arrow branches make with the 
   65: vector line.
   66: 
   67: \item arrowbackangle
   68: 
   69: For vector plots, determines the angle the arrow lines that return to the
   70: main line from the branches make with the arrow branches.
   71: 
   72: \end{itemize}
   73: 
   74: There are two ways of entering the information to be plotted, which are 
   75: accessed using the subtags of \textbf{curve}, \textbf{data} 
   76: (see ``Plotting Data Points'' section \ref{Authoring_Dynamic_Plot_Curve_Data}) 
   77: and \textbf{function}
   78: (see ``Plotting Functions'' section \ref{Authoring_Dynamic_Plot_Curve_Function}).
