TYSetMinAndDelta
================

.. us.tag  TYSetMinAndDelta ENGLISH TYSet Changed400

:ref:`TYSetMinAndDelta` sets the minimum value x-min and the distance delta
between 2 x-coordinates.

.. function::  bool = TYSetMinAndDelta(hData, rvMinDelta)
    bool = TYSetMinAndDelta(hData, rvMinDelta, bExt)

.. 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

   The handle of a dataset created with :ref:`TYCreate`.

.. uparam:: rvMinDelta

   *rvMinDelta* is a vector with 2 elements: *rvMinDelta[1]* is the minimum 
   value xmin; *rvMinDelta[2]* is the distance delta between 2 x-coordinates. 
   *rvMinDelta[2]* must be greater than 0.

.. uparam:: bExt

   This parameter specifies if the function will access the original data
   or the filtered data.

.. list-table::
   :header-rows: 1

   * - Value
     - Description
   * - -1
