auto_xy_Spline
==============

.. us.tag  auto_xy_Spline NOTREADYENGLISH auto_xy

The function is obsolete. New scripts should use the :ref:`XYSetFilterFunctions` 
function.

:ref:`auto_xy_Spline` creates a new dataset where the points are connected by a
spline.

.. function::  hDataNew = auto_xy_Spline(hData_Layer)
    hDataNew = auto_xy_Spline(hData_Layer, rsSmoothFactor)
    hDataNew = auto_xy_Spline(hData_Layer, rsSmoothFactor, nPoints)

.. us.return

**Return Value**

*hDataNew* is the handle of the new 2D dataset.

.. us.params

**Parameters**

.. uparam:: hData_Layer

   *hData_Layer* is a vector with one or two elements:

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

      * - Value
        - Meaning
      * - hData_Layer[1]
        - Handle of a dataset. The new dataset is added to the diagram to which the dataset hData_Layer[1] belongs.
      * - hData_Layer[1, 2]
        - The first element is the handle of a dataset and the second element is the handle of diagram (layer). The new dataset is added to the diagram with the handle hData_Layer[2].

.. uparam:: rsSmoothFactor

   *rsSmoothFactor* is a number  between 0 and 50. If the number greater than 0
   smoothing  is performed. The default value is 0.

.. uparam:: nPoints

   *nPoints* is the number of points of the new dataset. The minimum number of
   points is 2. The default value is 100 points.
