# 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.
|
||||
* Along these lines, please note that `pyqtgraph.opengl` will be deprecated soon and replaced with VisPy.
|
||||
|
||||
## Documentation
|
||||
|
||||
* Writing proper documentation and unit tests is highly encouraged. PyQtGraph uses nose / 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
|
||||
|
||||
* 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.
|
||||
|
||||
## Testing Setting up a test environment
|
||||
|
||||
### Dependencies
|
||||
|
||||
* tox
|
||||
* tox-conda
|
||||
* pytest
|
||||
* pytest-cov
|
||||
* pytest-xdist
|
||||
* pytest-faulthandler
|
||||
* Optional: pytest-xvfb
|
||||
|
||||
### 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. On each OS, we test the following 6 configurations
|
||||
|
||||
* Python2.7 with PyQt4
|
||||
* Python2.7 with PySide
|
||||
* Python3.6 with PyQt5-5.9
|
||||
* Python3.6 with PySide2-5.9
|
||||
* Python3.7 with PyQt5-5.12
|
||||
* Python3.7 with PySide2-5.12
|
||||
|
||||
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)

heavy leverage of numpy for number crunching, Qt's GraphicsView framework for

2D display, and OpenGL for 3D display.

Qt Bindings Test Matrix

Below is a table of the configurations we test and have confidence pyqtgraph will work with. All current operating major operating systems (Windows, macOS, Linux) are tested against this configuration. We recommend using the Qt 5.12 or 5.9 (either PyQt5 or PySide2) bindings.

Some users may need to call ``pip3`` instead. This method should work on

**Notes:**
|

|

For backward compatibility, image data is assumed to be in column-major order (column, row).
|
||||
However, most image data is stored in row-major order (row, column) and will need to be
|
||||
transposed before calling setImage()::
|
||||
|
||||
|
||||
imageitem.setImage(imagedata.T)
|
||||
|
||||
|
||||
This requirement can be changed by calling ``image.setOpts(axisOrder='row-major')`` or
|
||||
by changing the ``imageAxisOrder`` :ref:`global configuration option <apiref_config>`.
