Requirements
------------
* Python 2.7, or 3.x
pyqtgraph has adopted [NEP 29](https://numpy.org/neps/nep-0029-deprecation_policy.html).
This project supports:
* All minor versions of Python released 42 months prior to the project, and at minimum the two latest minor versions.
* All minor versions of numpy released in the 24 months prior to the project, and at minimum the last three minor versions.
* All minor versions of Qt 5 and Qt 6 currently supported by upstream Qt
Currently this means:
* Python 3.7+
* Qt 5.12-6.0
* Required
* PyQt 4.8+, PySide, PyQt5, or PySide2
* `numpy`
* PyQt5, PyQt6, PySide2 or PySide6
* `numpy` 1.17+
* Optional
* `scipy` for image processing
* `pyopengl` for 3D graphics
* `pyopengl` on macOS Big Sur only works with python 3.9.1+
* `hdf5` for large hdf5 binary format support
* `colorcet` for supplemental colormaps
* [`cupy`](https://docs.cupy.dev/en/stable/install.html) for CUDA-enhanced image processing
* On Windows, CUDA toolkit must be >= 11.1

HiDPI Displays
--------------
PyQtGraph has a method :func:`mkQApp <pyqtgraph.Qt.mkQApp>` that by default sets what we have tested to be the best combination of options to support hidpi displays, when in combination with non-hidpi secondary displays. For your application, you may have instantiated ``QApplication`` yourself, in which case we advise setting these options *before* runing ``QApplication.exec_()``.
For Qt6 bindings, this functionally "just works" without having to set any attributes.
On Versions of Qt >= 5.14 and < 6; you can get ideal behavior with the following lines::
os.environ["QT_ENABLE_HIDPI_SCALING"] = "1"
QApplication.setHighDpiScaleFactorRoundingPolicy(QtCore.Qt.HighDpiScaleFactorRoundingPolicy.PassThrough)
If you are on Qt >= 5.6 and < 5.14; you can get near ideal behavior with the following lines::
QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps)
With the later, ideal behavior was not achieved.

PyQt and PySide
@ -61,15 +83,16 @@ PyQtGraph supports two popular python wrappers for the Qt library: PyQt and PySi
APIs and functionality, but for various reasons (discussed elsewhere) you may prefer to use one package or the other. When
pyqtgraph is first imported, it automatically determines which library to use by making the fillowing checks:
#. If PyQt4 is already imported, use that
#. Else, if PySide is already imported, use that
#. Else, attempt to import PyQt4
#. If that import fails, attempt to import PySide.
#. If PyQt5 is already imported, use that

If you have both libraries installed on your system and you wish to force pyqtgraph to use one or the other, simply
make sure it is imported before pyqtgraph::

Parameter Trees
===============
.. currentmodule:: pyqtgraph.parametertree
Parameter trees are a system for handling hierarchies of parameters while automatically generating one or more GUIs to display and interact with the parameters.
This feature is commonly seen, for example, in user interface design applications which display a list of editable properties for each widget.
Parameters generally have a name, a data type (int, float, string, color, etc), and a value matching the data type. Parameters may be grouped and nested
to form hierarchies and may be subclassed to provide custom behavior and display widgets.
Parameters generally have a name, a data type (int, float, string, color, etc), and a value matching the data type. Parameters may be grouped and nested to form hierarchies and may be subclassed to provide custom behavior and display widgets.
PyQtGraph's parameter tree system works similarly to the model-view architecture used by some components of Qt: Parameters are purely data-handling classes
that exist independent of any graphical interface. A ParameterTree is a widget that automatically generates a graphical interface which represents
the state of a haierarchy of Parameter objects and allows the user to edit the values within that hierarchy. This separation of data (model) and graphical
interface (view) allows the same data to be represented multiple times and in a variety of different ways.

For more information, see the 'parametertree' example included with pyqtgraph and the API reference
- A :class:`Parameter` is a purely data-handling class that exists independent of any graphical interface.
- A :class:`ParameterItem` is an interactive graphical representation of a :class:`Parameter`.
- A :class:`ParameterTree` is a widget that automatically generates a graphical interface which represents the state of a hierarchy of Parameter objects and allows the user to edit the values within that hierarchy.
This separation of data (model) and graphical interface (view) allows the same data to be represented multiple times and in a variety of different ways.
For example, a floating point number parameter could be represented by a slider or a spinbox, or both.

"""
This example demonstrates the use of ImageView, which is a high-level widget for
displaying and analyzing 2D and 3D data. ImageView provides:
1. A zoomable region (ViewBox) for displaying the image
2. A combination histogram and gradient editor (HistogramLUTItem) for
controlling the visual appearance of the image
3. A timeline for selecting the currently displayed frame (for 3D data only).
4. Tools for very basic analysis of image data (see ROI and Norm buttons)
