S2PLOT Standard Primitives

The S2PLOT standard primitives are based on the PGPLOT primitives, having a very similiar functional interface, but with additional parameters for (x,y,z) data. Standard primitives include:

• Points
• Lines
• Circles
• Disks
• Rectangles
• Text
• Arrows

The appearance of the primitives is controlled through attributes:

• Colour
• Linewidth
• Character height
• Arrowhead styles

In addition, for creating scientific graphs, there are functions to control:

• Axes
• Axis labels

More advanced plotting features include:

• Data with error bars
• Parametric curves of the form fx(t), fy(t) and fz(t)
• Surfaces defined by functions of the form f(x, y)
• Surfaces defined by a 2-d array of nx * ny values
• Vector plots

The S2PLOT standard primitives are complemented by the native primatives.
