## Defining Plot Scales and Axes

The function `plenv` is used to define the scales and axes for simple graphs. `plenv` starts a new picture on the next subpage (or a new page if necessary), and defines the ranges of the variables required. The routine will also draw a box, axes, and numeric labels if requested.

For greater control over the size of the plots, axis labelling and tick intervals, more complex graphs should make use of the functions `plvpor`, `plvasp`, `plvpas`, `plwind`, `plbox`, and routines for manipulating axis labelling `plgxax` through `plszax`.
