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

.. _PythonQwt: https://pypi.python.org/pypi/PythonQwt


Building, installation, ...
---------------------------

The following packages are **required**: `PyQt5`_,
`PythonQwt`_, `guidata`_, `NumPy`_, `SciPy`_ and `Pillow`_.

.. _PyQt5: https://pypi.python.org/pypi/PyQt5
