    2: 
    3: The \textbf{gnuplot} tag allows an author to design a plot which is created
    4: when it is viewed.  This is intended for use in homework problems
    5: where each student needs to see a distinct plot.  It can be used in
    6: conjunction with a \textbf{script} tag to generate random plots.
    7: 
    8: The following parameters may be set:
    9: 
   10: \begin{itemize}
   11: \item \texttt{brief description of the plot} 
   12: This text is used as the \texttt{alt} parameter of the \texttt{img} tag 
   13: used to embed the plot.
   14: 
   15: \item \texttt{background color of image (xffffff)}
   16: See the section on color selection \ref{Authoring_Dynamic_Plot_Color_Selection}
   17: for help on specifying colors.
   18: 
   19: \item \texttt{foreground color of image (x000000)} 
   20: 
   21: See the section on color selection \ref{Authoring_Dynamic_Plot_Color_Selection}
   22: for help on specifying colors.
   23: 
   24: \item \texttt{height of image (pixels)}
   25: 
   26: \item \texttt{width of image (pixels)}
   27: 
   28: \item \texttt{Size of font to use} ``small'', ``medium'', or ``large''.  
   29: The font used for any text on the plot is set with this tag.
   30: 
   31: \item \texttt{Transparent image} ``Yes'' or ``No''.  
   32: If the image is transparent the background color will be ignored.
   33: 
   34: \item \texttt{Display grid} ``Yes'' or ``No''.  
   35: 
   36: \item \texttt{Number of samples for non-data plots}  If a \textbf{function} 
   37: \ref{Authoring_Dynamic_Plot_Curve_Function} tag is used to specify the
   38: \textbf{curve} \ref{Authoring_Dynamic_Plot_Curve}, this indicates the number
   39: of sample points to use.
   40: 
   41: \item \texttt{Draw border around plot} ``Yes'' or ``No''
   42: 
   43: \item \texttt{alignment for image in html} ``Left'', ``Center'', or ``Right''.
   44: This is the value used for the \texttt{align} parameter in the \texttt{img} 
   45: tag which embeds the plot in the problem.
   46: 
   47: \item \texttt{Width of plot when printed (mm)} The width in mm of the plot when
   48: it is printed.  The default is approximately one half of a U.S. letter size 
   49: page, 93 mm.
   50: 
   51: \item \texttt{Font size to use in TeX output (pts)} The size in points of text
   52: on the graph when it is printed out.
   53: 
   54: \item \texttt{Plot type} ``Cartesian'' or ``Polar''.  
   55: 
   56: \item \texttt{margin width (pts)} The left, right, top, or bottom margin width
   57: measured in points.
   58: 
   59: \item \texttt{Size of major tic marks} The size of the larger tic marks on the
   60: plot border or axes, measured in graph units.
   61: 
   62: \item \texttt{Size of minor tic marks} The size of the smaller tic marks on the
   63: plot border or axes, measured in graph units.
   64: 
   65: \end{itemize}
   66: 
   67: The \textbf{gnuplot} tag allows the use of the the following tags:
   68: 
   69: \begin{itemize}
   70: \item \textbf{curve} \ref{Authoring_Dynamic_Plot_Curve}
   71: \item \textbf{key}   \ref{Authoring_Dynamic_Plot_Key}
   72: \item \textbf{label} \ref{Authoring_Dynamic_Plot_Label}
   73: \item \textbf{axes}  \ref{Authoring_Dynamic_Plot_Axes}
   74: \item \textbf{tics}  \ref{Authoring_Dynamic_Plot_Tics}
   75: \item \textbf{title}, \textbf{xlabel}, and \textbf{ylabel} 
   76:       \ref{Authoring_Dynamic_Plot_Title_X_Y_Label}
