AutoScaleLin
============

.. us.tag  AutoScaleLin ENGLISH

:ref:`AutoScaleLin` calculates the parameters for the diagram's axes scaling.

.. function::  rvScale = AutoScaleLin(rsMin, rsMax)
    rvScale = AutoScaleLin(rsMin, rsMax, nLabel)

.. 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.

.. uparam:: nLabel

   *nLabel* is the number of axis labels.
