To mimic the old behavior, use ArrowItem.rotate() instead of the `angle` argument.
|
||||
- Deprecated graphicsWindow classes; these have been unnecessary for many years because
|
||||
widgets can be placed into a new window just by calling show().
|
||||
- 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.

|

----------
|
||||
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.

Support
|
||||
-------
|
||||
|
||||
Post at the [mailing list / forum](https://groups.google.com/forum/?fromgroups#!forum/pyqtgraph)
|
||||
|
||||
* Report issues on the [GitHub issue tracker](https://github.com/pyqtgraph/pyqtgraph/issues)
|
||||
* Post questions to the [mailing list / forum](https://groups.google.com/forum/?fromgroups#!forum/pyqtgraph) or [StackOverflow](https://stackoverflow.com/questions/tagged/pyqtgraph)
|
||||
|
||||
Installation Methods
|
||||
--------------------
|
||||
|
||||
* From pypi:
|
||||
`pip install pyqtgraph`
|
||||
* 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.
|
||||
anywhere that is importable from your project.
|
||||
* 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.
|
||||
The easiest way to learn pyqtgraph is to browse through the examples; run `python -m pyqtgraph.examples` for a menu.
|
||||
|
||||
The official documentation lives at http://pyqtgraph.org/documentation
|
||||
|
||||
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.
