YLOGBASE

Syntax: | `SET YLOGBASE n GET 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.
