# guiqwt: Python tools for curve and image plotting
[](./LICENSE)

## Important note
<img src="https://raw.githubusercontent.com/PlotPyStack/plotpy/master/doc/images/plotpy-banner.png">
guiqwt will soon be replaced by [plotpy](https://github.com/PlotPyStack/plotpy) which is a complete rewrite of the library, under more permissive license terms (BSD) with a lot of improvements (automatic test suite with ~70% test coverage, unified curve/image ready-to-use widgets, new documentation, ...).

See [documentation](https://guiqwt.readthedocs.io/en/latest/) for more details on
the library and [changelog](CHANGELOG.md) for recent history of changes.

## Overview
Based on ``PythonQwt`` (a pure Python/PyQt reimplementation of the curve
plotting Qwt C++ library, included in guiqwt base source code) and on the
scientific modules NumPy and SciPy, ``guiqwt`` is a Python library providing
efficient 2D data-plotting features (curve/image visualization and related
tools) for interactive computing and signal/image processing application
development. It is based on Qt graphical user interfaces library, and
currently supports both ``PyQt5`` and ``PySide2``.
Extension to ``PythonQwt``:
* set of tools for curve and image plotting
* GUI-based application development helpers
## Dependencies
### Requirements
* Python 3.7+
* [PyQt5](https://pypi.python.org/pypi/PyQt5)
* [QtPy](https://pypi.org/project/QtPy/)
* [PythonQwt](https://pypi.python.org/pypi/PythonQwt) (pure Python reimplementation of Qwt6 C++ library)
* [guidata](https://pypi.python.org/pypi/guidata)
* [NumPy](https://pypi.python.org/pypi/NumPy)
* [SciPy](https://pypi.python.org/pypi/SciPy)
* [Pillow](https://pypi.python.org/pypi/Pillow)
### Optional modules
* [pydicom](https://pypi.python.org/pypi/pydicom) for DICOM I/O support
## Building/Installation
### All platforms
The setup.py script supports the following extra options for
optimizing the image scaler engine with SSE2/SSE3 processors:
``--sse2`` or ``--sse3``.
### On GNU/Linux and MacOS platforms
```bash
python setup.py build install
```
### On Windows platforms with Microsoft Visual Studio
```cmd
python setup.py build -c msvc install
```
