-The gnuplot tag allows an author to design a plot which can
-be created on the fly. This is intended for use in homework problems
-where each student needs to see a distinct plot. It can be used in
-conjunction with a script tag to generate random plots.
-
-A gnuplot tag can contain the following sub-tags:
-
-
-
Plot Label
-
Allows you to place text at a given (x,y) coordinate on the plot.
-
Plot Title
-
The title of the plot
-
Plot Xlabel
-
The label on the horizontal axis of the plot
-
Plot Ylabel
-
The label on the vertical axis of the plot
-
Plot Axes
-
allows specification of the x and y ranges displayed in the plot
-
Plot Key
-
Lists the functions displayed in the plot.
-
Plot Curve
-
Sets the data used in the plot.
-
Plot Tics
-
Allows specification of the x and y coordinate 'tics' on the axes.
-This is mostly used to adjust the grid lines when a grid is displayed.

-my $curve_help_text = <<"ENDCURVEHELP";
-The curve tag is where you set the data to be plotted by gnuplot.
-There are two ways of entering the information:
-
-
Curve Data
-
Using a data tag you can specify the numbers used to produce
-the plot.
-
-By default, two data tags will be available in a plot. The
-first will specify X coordinates of the data and the second will
-give the Y coordinates of the data. When working with a linestyle that
-requires more than two data sets, inserting another data tag is
-required. Unfortunately, you must make sure the data tags appear
-in the order gnuplot expects the data.
-
-Specifying the data should usually be done with a perl variable or array,
-such as \@Xdata and \@Ydata. You may also specify numerical data seperated
-by commas. Again, the order of the data tags is important. The
-first tag will be the X data and the second will be the Y data.
-
-
Curve Function
-
The function tag allows you to specify the curve to be
-plotted as a formula that gnuplot can understand. Be careful using this
-tag - it is surprisingly easy to give gnuplot a function it cannot deal
-with properly. Be explicit: 2*sin(2*3.141592*x/4) will work but
-2sin(2*3.141592x/4) will not. If you do not receive any errors in the
-gnuplot data but still do not have an image produced, it is likely there
-is an error in your function tag.
