SET YLOGBASE n
|
Default: |
YLOGBASE = 0
|
YLOGBASE
determines whether the y-axis is to be linear or logarithmic.
YLOGBASE
should always be > 0
.
YLOGBASE |
meaning |
> 1.0 |
the y-axis will have a logarithmic scale.
The base will be the integer part of YLOGBASE , except for the special case:
1.05*e > YLOGBASE > 0.95*e , where e is the
base of the natural logarithms, e ≈ 2.718281828 , in which case the base
will be e . |
≤ 1.0 |
the y-axis will have a linear scale |
If YLOGBASE > 1.0
, then YMIN
and
YMAX
are assumed to be the exponents for the minimum and
maximum values on the y-axis. The maximum value displayed on the y-axis is
YLOGBASEYMAX
and the minimum value displayed on the y-axis is
YLOGBASEYMIN
. Integer exponents are always used for the axis numbering, so
the y-axis may not begin and/or end on a large tic mark.
If YLOGBASE = 10.0
, the small tic marks on the y-axis can be specified exactly with
YNSINCS
. If small tic marks are desired at the locations
j*10n
, where 2 ≤ j ≤ 9
, then set
YNSINCS = -j
. For example, if you want small tic marks at 2*10n
,
4*10n
, 5*10n
, and
8*10n
, then set
SET YNSINCS -2458
.
If YLOGBASE ≤ 1.0
, YMIN
and YMAX
are the actual minimum and
maximum values for the y-axis; and the y-axis always begins and
ends on large tic marks.
