XYZSetIsoValuesScaleType
========================

.. index:: XYZSetIsoValuesScaleType

.. us.tag  XYZSetIsoValuesScaleType NOTREADYENGLISH New412 XYZSet_iso

:ref:`XYZSetIsoValuesScaleType` specifies how the isoline values are calculated 
(atuomatically or manually).

.. function::  bool = XYZSetIsoValuesScaleType(hData, rvScaleInfo)

.. us.return

**Return Value**

If the function succeeds, the return value bool is TRUE (1); otherwise it is FALSE (0). 

.. us.params

**Parameters**

.. uparam:: hData

   A handle for a dataset created with :ref:`XYZCreate` or :ref:`XYZCreateFromMatrix`.

.. uparam:: rvScaleInfo

   *rvScaleInfo* is a vector with three elements 
   (rvScaleInfo = [bAutoscale, nScaleType, nAutoValuesMax]):

.. list-table::
   :header-rows: 0

   * - bAutoscale
     - 0: No autoscaling (nScaleType and nAutoValues will be ignored). The isoline values will be specified by the user. 1: Automatic calculation of isoline values.
   * - nScaleType
     - 0: Standard, 1: Steps 1,2,5 (nAutoValues will be ignored), 2: Linear scaling.
   * - nAutoValuesMax
     - If nScaleType is 0 or 2, this value will specify the number of isoline values created. The value 0 does not change the number of isolines.
