- #1211: Add support for running pyside2-uic binary to dynamically compile ui files
|
||||
|
||||
API / behavior changes:
|
||||
- Deprecated graphicsWindow classes; these have been unnecessary for many years because
|
||||
widgets can be placed into a new window just by calling show().
|
||||
- #158: Make DockArea compatible with Qt Designer
|
||||
- #406: Applying alpha mask on numpy.nan data values
|
||||
- #566: ArrowItem's `angle` option now rotates the arrow without affecting its coordinate system.
|
||||
The result is visually the same, but children of ArrowItem are no longer rotated
|
||||
(this allows screen-aligned text to be attached more easily).
|
||||
To mimic the old behavior, use ArrowItem.rotate() instead of the `angle` argument.
|
||||
- #673: Integer values in ParameterTree are now formatted as integer (%d) by default, rather than
|
||||
scientific notation (%g). This can be overridden by providing `format={value:g}` when
|
||||
creating the parameter.
|
||||
- #374: ConsoleWidget uses the console's namespace as both global and local scope, which
|
||||
- #410: SpinBox siPrefix without suffix is not longer allowed, select only numerical portion of text on focus-in
|
||||
allows functions defined in the console to access the global namespace.
|
||||
- #479,521: ParameterTree simple parameters check types before setting value
|
||||
- #555: multiprocess using callSync='sync' no longer returns a future in case of timeout
|
||||
- #583: eq() no longer compares array values if they have different shape
|
||||
- #589: Remove SpiralROI (this was unintentionally added in the first case)
|
||||
- #593: Override qAbort on slot exceptions for PyQt>=5.5
|
||||
- #657: When a floating Dock window is closed, the dock is now returned home

# Contributing to PyQtGraph
|
||||
|
||||
Contributions to pyqtgraph are welcome!
|
||||
|
||||
Please use the following guidelines when preparing changes:
|
||||
|
||||
## Submitting Code Changes
|
||||
|
||||
* The preferred method for submitting changes is by github pull request against the "develop" branch.
|
||||
* Pull requests should include only a focused and related set of changes. Mixed features and unrelated changes may be rejected.
|
||||
* For major changes, it is recommended to discuss your plans on the mailing list or in a github issue before putting in too much effort.
|
||||
* The following deprecations are being considered by the maintainers
|
||||
* `pyqtgraph.opengl` may be deprecated and replaced with `VisPy` functionality
|
||||
* After v0.11, pyqtgraph will adopt [NEP-29](https://numpy.org/neps/nep-0029-deprecation_policy.html) which will effectively mean that python2 support will be deprecated
|
||||
* Qt4 will be deprecated shortly, as well as Qt5<5.9 (and potentially <5.12)
|
||||
|
||||
## Documentation
|
||||
|
||||
* Writing proper documentation and unit tests is highly encouraged. PyQtGraph uses pytest style testing, so tests should usually be included in a tests/ directory adjacent to the relevant code.
|
||||
* Documentation is generated with sphinx; please check that docstring changes compile correctly
|
||||
|
||||
## Style guidelines
|
||||
|
||||
### Rules
|
||||
|
||||
* PyQtGraph prefers PEP8 for most style issues, but this is not enforced rigorously as long as the code is clean and readable.
|
||||
* Use `python setup.py style` to see whether your code follows the mandatory style guidelines checked by flake8.
|
||||
* Exception 1: All variable names should use camelCase rather than underscore_separation. This is done for consistency with Qt
|
||||
* Exception 2: Function docstrings use ReStructuredText tables for describing arguments:
|
||||
|
||||
```text
|
||||
============== ========================================================
|
||||
**Arguments:**
|
||||
argName1 (type) Description of argument
|
||||
argName2 (type) Description of argument. Longer descriptions must
|
||||
be wrapped within the column guidelines defined by the
|
||||
"====" header and footer.
|
||||
============== ========================================================
|
||||
```
|
||||
|
||||
QObject subclasses that implement new signals should also describe
|
||||
these in a similar table.
|
||||
|
||||
### Pre-Commit
|
||||
|
||||
PyQtGraph developers are highly encouraged to (but not required) to use [`pre-commit`](https://pre-commit.com/). `pre-commit` does a number of checks when attempting to commit the code to ensure it conforms to various standards, such as `flake8`, utf-8 encoding pragma, line-ending fixers, and so on. If any of the checks fail, the commit will be rejected, and you will have the opportunity to make the necessary fixes before adding and committing a file again. This ensures that every commit made conforms to (most) of the styling standards that the library enforces; and you will most likely pass the code style checks by the CI.
|
||||
|
||||
To make use of `pre-commit`, have it available in your `$PATH` and run `pre-commit install` from the root directory of PyQtGraph.
|
||||
|
||||
## Testing Setting up a test environment
|
||||
|
||||
### Dependencies
|
||||
|
||||
* tox
|
||||
* tox-conda
|
||||
* pytest
|
||||
* pytest-cov
|
||||
* pytest-xdist
|
||||
* Optional: pytest-xvfb
|
||||
|
||||
If you have `pytest<5` (used in python2), you may also want to install `pytest-faulthandler==1.6` plugin to output extra debugging information in case of test failures. This isn't necessary with `pytest>=5`
|
||||
|
||||
### Tox
|
||||
|
||||
As PyQtGraph supports a wide array of Qt-bindings, and python versions, we make use of `tox` to test against most of the configurations in our test matrix. As some of the qt-bindings are only installable via `conda`, `conda` needs to be in your `PATH`, and we utilize the `tox-conda` plugin.
|
||||
|
||||
* Tests for a module should ideally cover all code in that module, i.e., statement coverage should be at 100%.
|
||||
* To measure the test coverage, un `pytest --cov -n 4` to run the test suite with coverage on 4 cores.
|
||||
|
||||
### Continous Integration
|
||||
|
||||
For our Continuous Integration, we utilize Azure Pipelines. Tested configurations are visible on [README](README.md). More information on coverage and test failures can be found on the respective tabs of the [build results page](https://dev.azure.com/pyqtgraph/pyqtgraph/_build?definitionId=1)

PyQtGraph is intended for use in mathematics / scientific / engineering applications.
|
||||
Despite being written entirely in python, the library is fast due to its
|
||||
heavy leverage of numpy for number crunching, Qt's GraphicsView framework for
|
||||
2D display, and OpenGL for 3D display.
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
* PyQt 4.7+, PySide, or PyQt5
|
||||
* python 2.6, 2.7, or 3.x
|
||||
* NumPy
|
||||
* For 3D graphics: pyopengl and qt-opengl
|
||||
* Known to run on Windows, Linux, and Mac.
|
||||
* Python 2.7, or 3.x
|
||||
* Required
|
||||
* PyQt 4.8+, PySide, PyQt5, or PySide2
|
||||
* `numpy`
|
||||
* Optional
|
||||
* `scipy` for image processing
|
||||
* `pyopengl` for 3D graphics
|
||||
* `hdf5` for large hdf5 binary format support

Qt Bindings Test Matrix
|
||||
-----------------------
|
||||
|
||||
The following table represents the python environments we test in our CI system. Our CI system uses Ubuntu 18.04, Windows Server 2019, and macOS 10.15 base images.
|
||||
|
||||
| Qt-Bindings | Python 2.7 | Python 3.6 | Python 3.7 | Python 3.8 |
|
||||
| :------------- | :----------------: | :----------------: | :----------------: | :----------------: |
|
||||
| PyQt-4 | :white_check_mark: | :x: | :x: | :x: |
|
||||
| PySide1 | :white_check_mark: | :x: | :x: | :x: |
|
||||
| PyQt5-5.9 | :x: | :white_check_mark: | :x: | :x: |
|
||||
| PySide2-5.13 | :x: | :x: | :white_check_mark: | :x: |
|

| PyQt5-Latest | :x: | :x: | :x: | :white_check_mark: |
|
||||
| PySide2-Latest | :x: | :x: | :x: | :white_check_mark: |
|
||||
|
||||
* pyqtgraph has had some incompatibilities with PySide2 versions 5.6-5.11, and we recommend you avoid those versions if possible
|
||||
* on macOS with Python 2.7 and Qt4 bindings (PyQt4 or PySide) the openGL related visualizations do not work reliably

Installation Methods
|
||||
--------------------
|
||||
|
||||
* To use with a specific project, simply copy the pyqtgraph subdirectory
|
||||
anywhere that is importable from your project. PyQtGraph may also be
|
||||
used as a git subtree by cloning the git-core repository from github.
|
||||
* To install system-wide from source distribution:
|
||||
`$ python setup.py install`
|
||||
* For installation packages, see the website (pyqtgraph.org)
|
||||
* On debian-like systems, pyqtgraph requires the following packages:
|
||||
python-numpy, python-qt4 | python-pyside
|
||||
For 3D support: python-opengl, python-qt4-gl | python-pyside.qtopengl
|
||||
* From PyPI:
|
||||
* Last released version: `pip install pyqtgraph`
|
||||
* Latest development version: `pip install git+https://github.com/pyqtgraph/pyqtgraph@master`
|
||||
* From conda
|
||||
* Last released version: `conda install -c conda-forge pyqtgraph`
|
||||
* To install system-wide from source distribution: `python setup.py install`
|
||||
* Many linux package repositories have release versions.
|
||||
* To use with a specific project, simply copy the pyqtgraph subdirectory
|
||||
anywhere that is importable from your project.
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
There are many examples; run `python -m pyqtgraph.examples` for a menu.
|
||||
The official documentation lives at https://pyqtgraph.readthedocs.io
|
||||
|
||||
Some (incomplete) documentation exists at this time.
|
||||
* Easiest place to get documentation is at <http://www.pyqtgraph.org/documentation>
|
||||
* If you acquired this code as a .tar.gz file from the website, then you can also look in
|
||||
doc/html.
|
||||
* If you acquired this code via GitHub, then you can build the documentation using sphinx.
|
||||
From the documentation directory, run:
|
||||
`$ make html`
|
||||
|
||||
Please feel free to pester Luke or post to the forum if you need a specific
|
||||
section of documentation to be expanded.
|
||||
The easiest way to learn pyqtgraph is to browse through the examples; run `python -m pyqtgraph.examples` to launch the examples application.

Installation
|
||||
============
|
||||
|
||||
PyQtGraph does not really require any installation scripts. All that is needed is for the pyqtgraph folder to be placed someplace importable. Most people will prefer to simply place this folder within a larger project folder. If you want to make pyqtgraph available system-wide, use one of the methods listed below:
|
||||
PyQtGraph depends on:
|
||||
|
||||
* **Debian, Ubuntu, and similar Linux:** Download the .deb file linked at the top of the pyqtgraph web page or install using apt by putting "deb http://luke.campagnola.me/debian dev/" in your /etc/apt/sources.list file and install the python-pyqtgraph package.
|
||||
* **Arch Linux:** Looks like someone has posted unofficial packages for Arch (thanks windel). (https://aur.archlinux.org/packages.php?ID=62577)
|
||||
* **Windows:** Download and run the .exe installer file linked at the top of the pyqtgraph web page.
|
||||
* **Everybody (including OSX):** Download the .tar.gz source package linked at the top of the pyqtgraph web page, extract its contents, and run "python setup.py install" from within the extracted directory.
|
||||
* Python 2.7 or Python 3.x
|
||||
* A Qt library such as PyQt4, PyQt5, PySide, or PySide2
|
||||
* numpy
|
||||
|
||||
The easiest way to meet these dependencies is with ``pip`` or with a scientific
|
||||
python distribution like Anaconda.
|
||||
|
||||
There are many different ways to install pyqtgraph, depending on your needs:
|
||||
|
||||
pip
|
||||
---
|
||||
|
||||
The most common way to install pyqtgraph is with pip::
|
||||
|
||||
$ pip install pyqtgraph
|
||||
|
||||
Some users may need to call ``pip3`` instead. This method should work on all
|
||||
platforms.
|
||||
|
||||
conda
|
||||
-----
|
||||
|
||||
pyqtgraph is on the default Anaconda channel::
|
||||
|
||||
$ conda install pyqtgraph
|
||||
|
||||
It is also available in the conda-forge channel::
|
||||
|
||||
$ conda install -c conda-forge pyqtgraph
|
||||
|
||||
From Source
|
||||
-----------
|
||||
|
||||
To get access to the very latest features and bugfixes you have three choices:
|
||||
|
||||
1. Clone pyqtgraph from github::
|
||||
|
||||
$ git clone https://github.com/pyqtgraph/pyqtgraph
|
||||
$ cd pyqtgraph
|
||||
|
||||
Now you can install pyqtgraph from the source::
|
||||
|
||||
$ pip install .
|
||||
|
||||
2. Directly install from GitHub repo::
|
||||
|
||||
$ pip install git+git://github.com/pyqtgraph/pyqtgraph.git@develop
|
||||
|
||||
You can change ``develop`` of the above command to the branch name or the
|
||||
commit you prefer.
|
||||
|
||||
3. You can simply place the pyqtgraph folder someplace importable, such as
|
||||
inside the root of another project. PyQtGraph does not need to be "built" or
|
||||
compiled in any way.
|
||||
|
||||
Other Packages
|
||||
--------------
|
||||
|
||||
Packages for pyqtgraph are also available in a few other forms:
|
||||
|
||||
* **Debian, Ubuntu, and similar Linux:** Use ``apt install python-pyqtgraph`` or
|
||||
download the .deb file linked at the top of the pyqtgraph web page.
|
||||
* **Arch Linux:** https://www.archlinux.org/packages/community/any/python-pyqtgraph/
|
||||
* **Windows:** Download and run the .exe installer file linked at the top of the

* Right button drag: Scales the scene. Dragging left/right scales horizontally; dragging up/down scales vertically (although some scenes will have their x/y scales locked together). If there are x/y axes fisible in the scene, then right-dragging over the axis will _only_ affect that axis.
|
||||
* Right button click: Clicking the right button in most cases will show a context menu with a variety of options depending on the object(s) under the mouse cursor.
|
||||
* Middle button (or wheel) drag: Dragging the mouse with the wheel pressed down will always pan the scene (this is useful in instances where panning with the left button is prevented by other objects in the scene).

For machines where dragging with the right or middle buttons is difficult (usually Mac), another mouse interaction mode exists. In this mode, dragging with the left mouse button draws a box over a region of the scene. After the button is released, the scene is scaled and panned to fit the box. This mode can be accessed in the context menu or by calling::
