In addition, as a special exception, Gerard Vermeulen gives permission to link PyQwt dynamically with non-free versions of Qt and PyQt, and to distribute PyQwt in this form, provided that equally powerful versions of Qt and PyQt have been released under the terms of the GNU General Public License.

If PyQwt is dynamically linked with non-free versions of Qt and PyQt, PyQwt becomes a free plug-in for a non-free program.

Abstract:

PyQwt is a set of Python bindings for the Qwt C++ class library which extends the Qt framework with widgets for scientific, engineering and financial applications. It provides a widget to plot 2-dimensional data and various widgets to display and control bounded or unbounded floating point values.

The main features of PyQwt are:

it really shines with the Numerical Python extension, NumPy, numarray, and Numeric. These extension modules add new data types to Python which turn Python into an ideal system for numerical computing and experimentation, better than MatLab and IDL.
it requires and extends PyQt, a set of Python bindings for Qt.
it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions (either NumPy, or numarray, or Numeric or any combination) and optionally SciPy in a GUI Python application or in an interactive Python session.
it runs on POSIX, MacOS/X and Windows (any operating system supported by Qt and Python).
