-<dl>
-<dt> Plot Label
- <dd> Allows you to place text at a given (x,y) coordinate on the plot.
-<dt> Plot Title
- <dd> The title of the plot
-<dt> Plot Xlabel
- <dd> The label on the horizontal axis of the plot
-<dt> Plot Ylabel
- <dd> The label on the vertical axis of the plot
-<dt> Plot Axes
- <dd> allows specification of the x and y ranges displayed in the plot
-<dt> Plot Key
- <dd> Lists the functions displayed in the plot.
-<dt> Plot Curve
- <dd> Sets the data used in the plot.
-<dt> Plot Tics
- <dd> 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.

-The <b>curve</b> tag is where you set the data to be plotted by gnuplot.
-There are two ways of entering the information:
-<dl>
- <dt> Curve Data
- <dd> Using a <b>data</b> tag you can specify the numbers used to produce
-the plot.
-<p>
-By default, two <b>data</b> 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 <b>data</b> tag is
-required. Unfortunately, you must make sure the <b>data</b> tags appear
-in the order gnuplot expects the data.
-</p><p>
-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 <b>data</b> tags is important. The
-first tag will be the X data and the second will be the Y data.
-</p>
- <dt> Curve Function
- <dd> The <b>function</b> tag allows you to specify the curve to be
-plotted as a formula that gnuplot can understand. <b>Be careful using this
-tag.</b> 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 <b>function</b> tag.
