SCALES

COMMENSURATE

 If the \COMMENSURATE qualifier is used, the axes will be drawn with
 commensurate scaling, that is, the lengths of both axes will be
 adjusted to give a commensurate graph.  The lengths of the axes are
 adjusted at the time the SCALES\COMMENSURATE command is given, which
 means that if you change windows after the SCALES\COMMENSURATE command,
 the axis lengths will be incorrect. Choose the window you want and then
 set the axis scales.

nlxinc

 initial value:  nlxinc = 5
 default value if not entered:  nlyinc = 0

 nlxinc < 0 - the number of large tic marks on the x-axis will
              be nlxinc + 1. If XLOG > 1, logarithmic x-axis,
              nlxinc may be changed to avoid fractional powers.
              If XLOG < 1, linear x-axis, the x-axis minimum and
              maximum will not be labeled with numbers.
 nlxinc = 0 - the number of large tic marks on the x-axis will
              be automatically determined for the user
              The virtual x-axis minimum and maximum will be
              determined, so the x-axis may not begin or end
              at a large tic mark
 nlxinc > 0 - the number of large tic marks on the x-axis will
              be nlxinc + 1. If XLOG > 1, logarithmic x-axis,
              nlxinc may be changed to avoid fractional powers.
              If XLOG < 1, linear x-axis, nlxinc will not be changed.

nlyinc

 initial value:  nlyinc = 5
 default value if not entered:  nlyinc = 0

 nlyinc < 0 - the number of large tic marks on the y-axis will
              be nlyinc + 1. If YLOG > 1, logarithmic y-axis,
              nlyinc may be changed to avoid fractional powers.
              If YLOG < 1, linear y-axis, the y-axis minimum and
              maximum will not be labeled with numbers.
 nlyinc = 0 - the number of large tic marks on the y-axis will
              be automatically determined for the user
              The virtual y-axis minimum and maximum will be
              determined, so the y-axis may not begin or end
              at a large tic mark
 nlyinc > 0 - the number of large tic marks on the y-axis will
              be nlyinc + 1. If YLOG > 1, logarithmic y-axis,
              nlyinc may be changed to avoid fractional powers.
              If YLOG < 1, linear y-axis, nlyinc will not be changed.
