Create axis at arbitrary positions.
AXES('position', RECT) opens up an axis at the specified location
and returns a handle to it.
RECT = [left, bottom, width, height] specifies the location and
size of the side of the axis box, relative to the lower-left
corner of the Figure window, and in in normalized units where (0,0)
is the lower-left corner and (1.0,1.0) is the upper-right.
AXES, by itself, creates the default full-window axis and returns
a handle to it.
AXES(H) makes the axis with handle H current.
Execute GET (H) to see a list of axes object properties and
their current values. Execute SET (H) to see a list of axes
object properties and legal property values.
