Options (for parameters XOPT and YOPT):
A : draw Axis (X axis is horizontal line Y=0, Y axis is vertical
line X=0).
B : draw bottom (X) or left (Y) edge of frame.
C : draw top (X) or right (Y) edge of frame.
G : draw Grid of vertical (X) or horizontal (Y) lines.
I : Invert the tick marks; ie draw them outside the viewport
instead of inside.
L : label axis Logarithmically (see below).
N : write Numeric labels in the conventional location below the
viewport (X) or to the left of the viewport (Y).
P : extend ("Project") major tick marks outside the box (ignored if
option I is specified).
M : write numeric labels in the unconventional location above the
viewport (X) or to the right of the viewport (Y).
T : draw major Tick marks at the major coordinate interval.
S : draw minor tick marks (Subticks).
V : orient numeric labels Vertically. This is only applicable to Y.
The default is to write Y-labels parallel to the axis.
1 : force decimal labelling, instead of automatic choice (see PGNUMB).
2 : force exponential labelling, instead of automatic.
When PGENV calls PGBOX, it sets both XOPT and YOPT according to the value of its parameter
