DESCRIPTION

Pl_space or pl_3space must be used before any of the graphic primitives to declare the amount of space necessary. See plot3(5).

Pl_box or pl_3box draws a box between the two given opposite points. The ''pen'' will be left at the second point.

Pl_circle draws a circle of radius r with center at the point (x, y). Note that circle and arc cannot be transformed in three space if one is using a filter to do that.

Pl_arc draws an arc of a circle with center at the point (x, y) between the points (x0, y0) and (x1, y1).

String arguments to pl_label and pl_linmod are terminated by nulls and do not contain new-lines.

There are also 2-D and 3_D double-precision versions, with arguments identical to their counterparts above. The naming conventions are to change the prefix to "pd"; examples are thus pd_point and pd_3point. Vector versions for 3_D (also double-precision) are prefixed "pdv", as in pdv_3point.

See plot3(5) and plot(5) for a description of the effect of the remaining functions.

WARNINGS

Color specification and three-dimensional primitives are BRL extensions to the "unix plot" language that are not generally found on other systems.
