Set the viewport to be as large as possible and still leave room for tick marks and their labels.

Description:

The vp command sets the 2D viewport. The reset vp command can be used to reset the viewport to its default values (0.25, 0.95, 0.15, 0.90). full might be used when creating output for presentations or publications.

vp differs from wp , though the two are similar. vp sets the portion of the window into which to put the plot. Thus its coordinates are in window coordinates. wp determines which part of the problem (mesh) to plot, and so its coordinates are in problem ("physical" or "world") coordinates.

Examples:

vp .25, .75, .15, .65
