AutoScaleLog
============

.. us.tag  AutoScaleLog ENGLISH

:ref:`AutoScaleLog` calculates parameters for
logarithmic scaled diagram axes.

.. function::  rvScale = AutoScaleLog(rsMin, rsMax)

.. us.return

**Return Value**

*rvScale* = [rsMin, rsMax, rsDelta, rsFormat] *rvScale* is
a real vector with 4 elements: *rvScale* = [rsMin, rsMax, rsDelta,
rsFormat]. *rsMin* is a recommended minimum value for the diagram
axis and *rsMax* a recommended maximum value. *rsDelta* is the
recommended distance between 2 labels and *rsFormat* is the
recommended number of decimal places for the labels. If *rsFormat*
is negative, an exponential format is recommended.

.. us.params

**Parameters**

.. uparam:: rsMin

   *rsMin* is the approximate minimum value of the axis.

.. uparam:: rsMin

   *rsMin* is the approximate maximum value of the axis.
