Running pyqtgraph with python -OO gives the following crash
colin@desktop:~$ python3 -OO -c 'import pyqtgraph'

fn.__doc__ = fn.__doc__ + str(Gradients.keys()).strip('[').strip(']')
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'
The cause is the @addGradientListToDocstring() annotation in
GradientEditorItem.py that cannot handle functions without docstrings as
produced when using the python -OO option.
Fix this by only adding the gradient list to the docstring if the docstring is
not None.

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
Documentation
There are many examples; run python -m pyqtgraph.examples for a menu.
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.
