The curve tag is where you set the data to be plotted by gnuplot.
The following parameters may be present in the curve tag and allow access to most of the formatting parameters for a curve in gnuplot.
If a key is present, the name of the curve will appear with a sample of its line type.
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.
The thickness of the line drawn by plotting engine. This parameter may not apply to all linestyles.
This parameter may not apply to all linestyles.
This parameter may not apply to all linestyles. The size of the points, in pixels, present on the line. Some point types are not affected by this parameter.
This parameter controls the pont to fill for fillled curves.
For vector plots, controls where in the vector the arrow head(s) appear
For vector plots controls the fill style of the arrow.
For vector plots determines the distance between the vector line end and the tip of the arrow.
For vector plots, determines the angle the arrow branches make with the vector line.
For vector plots, determines the angle the arrow lines that return to the main line from the branches make with the arrow branches.
There are two ways of entering the information to be plotted, which are accessed using the subtags of curve, data (see "Plotting Data Points" section ) and function (see "Plotting Functions" section ).
