plbox(xopt, xtick, nxsub, yopt, ytick, nysub)

  plbox

[] Draws a box around the currently defined viewport, and labels it with world coordinate values appropriate to the window. Thus plbox should only be called after defining both viewport and window. The character strings xopt and yopt specify how the box should be drawn as described below. If ticks and/or subticks are to be drawn for a particular axis, the tick intervals and number of subintervals may be specified explicitly, or they may be defaulted by setting the appropriate arguments to zero.

[] xopt (char *, input):[]Pointer to character string specifying options for horizontal axis. The string can include any combination of the following letters (upper or lower case) in any order:

[] xtick (PLFLT, input):[]World coordinate interval between major ticks on the x axis. If it is set to zero, PLplot automatically generates a suitable tick interval.

[] nxsub (PLINT, input):[]Number of subintervals between major x axis ticks for minor ticks. If it is set to zero, PLplot automatically generates a suitable minor tick interval.

[] yopt (char *, input):[]Pointer to character string specifying options for vertical axis. The string can include any combination of the letters defined above for xopt, and in addition may contain:

[] ytick (real, input):[]World coordinate interval between major ticks on the y axis. If it is set to zero, PLplot automatically generates a suitable tick interval.

[] nysub (PLINT, input):[]Number of subintervals between major y axis ticks for minor ticks. If it is set to zero, PLplot automatically generates a suitable minor tick interval.
