auto_xyz_CreateIsolines
=======================

.. index:: auto_xyz_CreateIsolines

.. us.tag  auto_xyz_CreateIsolines NOTREADYENGLISH auto_xyz

:ref:`auto_xyz_CreateIsolines` creates
isolines for a 3D dataset.

.. function::  bool = auto_xyz_CreateIsolines(hData, z1Delta)
    bool = auto_xyz_CreateIsolines(hData, z1Delta, z1Max)
    bool = auto_xyz_CreateIsolines(hData, z1Delta, z1Max, z2Delta)
    bool = auto_xyz_CreateIsolines(hData, z1Delta, z1Max, z2Delta, z2Max)
    bool = auto_xyz_CreateIsolines(hData, z1Delta, z1Max, z2Delta, z2Max, z3Delta)
    bool = auto_xyz_CreateIsolines(hData, z1Delta, z1Max, z2Delta, z2Max, z3Delta, z3Max)

.. us.return

**Return Value**

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

.. us.params

**Parameters**

.. uparam:: hData

   The handle of a 3D dataset created with :ref:`XYZCreate`.

.. uparam:: z1Delta

   *z1Delta* if the function is called with two
   parmeters, isolines  from the minimum value to the maximul value in
   steps of *z1Delta* will be created.

.. us.example

**Example**

The following example will create the isolines 210 (minimum of a
fuel consumtion map is 207), 220, 230, 240, 250, 300, 350 and so on up to
500.

::

   ...
   hData = auto_LoadDataset("Diagram 1", "rpm", "torque", "fuel");
   auto_xyz_CreateIsolines(hData, 10, 250, 50, 500);
