PyTecplot
=========
The pytecplot library is a high level API that connects your Python script
to the power of the |Tecplot 360| visualization engine. It offers line
plotting, 2D and 3D surface plots in a variety of formats, and 3D volumetric
visualization. Familiarity with |Tecplot 360| and the |Tecplot 360|
macro language is helpful, but not required.
Documentation
-------------
The full documentation is here: https://www.tecplot.com/docs/pytecplot
.. note::
|PyTecplot| is supported on the three latest releases of Python, 64-bit
only. |PyTecplot| does not support 32 bit Python. Please refer to
INSTALL.rst for installation instructions and environment setup. For the
best experience, developers are encouraged to use the **latest version of
Python**.
Quick Start
-----------
Please refer to the documentation for detailed installation instructions and
environment setup. The short of it is something like this::
pip install pytecplot
Linux and OSX users may have to set ``LD_LIBRARY_PATH`` or
``DYLD_LIBRARY_PATH`` to the directories containing the |Tecplot 360|
dynamic libraries. Please refer to the documentation at
https://www.tecplot.com/docs/pytecplot for detailed information regarding setup
and use. In addition, the web page
https://www.tecplot.com/support/faqs/pytecplot contains a list of answered
questions you may have about |PyTecplot| in general.

PyTecplot 1.4.2
^^^^^^^^^^^^^^^
Released with Tecplot 360 2021 R2
* New API: `Cartesian3DFieldPlot.transient_zone_visibility` and
`Cartesian2DFieldPlot.transient_zone_visibility` defines the visibility
policy of transient data at the current solution time.

and renamed to ``Fieldmap.show_isosurface``.
* Deprecated from 2D plot types: properties ``show_slices``,
``show_streamtraces`` and ``show_iso_surfaces`` are now only accessible from
the 3D plot type.
* Several improvements to documentation and installation notes.
These methods and improvements will require either the April 2020 Beta or the
upcoming release of Tecplot 360 2020 R1:
* macOS: PyTecplot in batch mode can now export images with Python as installed
by Brew or MacPorts.

IJK range parameters.
* Bug fix: ``IndexRange`` max value of zero is now interpreted as the first
index in the range instead of the last index.
* Many documentation and example script updates and fixes.
PyTecplot 1.0.0
^^^^^^^^^^^^^^^
Released with Tecplot 360 2019 R1
* This is the first release of a guaranteed-stable interface of PyTecplot.
Following this, the API will adhere closely to the guidelines enumerated
by `Semantic Versioning 2.0.0 <https://semver.org>`_.
* Deprecation warnings from previous versions have been elevated to errors.

removing the need for the user to do this in client code.

* Interface change: getting a single page, frame, linemap, zone or variable
by name no longer raises and exception if no match is found. Instead the
methods emit a warning and return None.
* Setting array data from Python into PyTecplot now orders of magnitude faster
if Numpy is installed for batch-mode.
* New property: ``Variable.lock_mode`` to get lock status of the variable.
* New multiprocessing examples.
* Several documentation corrections and minor fixes.
* Removed: slice and isosurface properties are 3D only and have now been
removed from the Cartesian2DFieldPlot class.
PyTecplot 0.12.0
^^^^^^^^^^^^^^^^
Released with Tecplot 360 2018 R2.1

* Bug fix: Dataset.copy_zones() now copies all zones by default.
* Better PyTecplot Connections exception handling.
* Updated installation documentation addressing differences between batch and connected modes.
* Removed from API: ``PolarView.reset_to_entire_circle()``. Scripts should use
``PolarLineAxis.reset_to_entire_circle()`` instead.
* Fixed recording of PyTecplot copy/paste frame.
* Added ability for PyTecplot to subsequently acquire a license if the first attempt
failed due to contention.
PyTecplot 0.11.0

* Performance: tp.session.suspend() context now delays GUI updates during complex operations. This
is now fully supported with Tecplot 360 2018 R2 and later.
* Performance: The underlying protocol for connect mode has changed to "Protocol Buffers" by
Google. PyTecplot is still backwards compatible with the previous versions of the TecUtil Server,
but newer versions of Tecplot 360 will now require PyTecplot 0.11 or later.
* Import of the ``tecplot`` Python module is now "on-demand" and should be faster for most users.
PyTecplot 0.10.4
^^^^^^^^^^^^^^^^
* Bug fix: state changes now successfully emitted on exit from suspend context
PyTecplot 0.10.3
