I am proud to announce PyQwt-4.1. What is PyQwt? - it 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. - it requires and extends PyQt, a set of Python bindings for Qt. - it really shines with either Numeric, numarray or both. Numeric and/or numarray extend the Python language with new data types which turn Python into an ideal system for numerical computing and experimentation, better than MatLab and IDL. - it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions (either Numeric, or numarray or both) 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). The home page of PyQwt is http://pyqwt.sourceforge.net. Main changes in PyQwt-4.1: 1. supports PyQt-3.13, -3.12, PyQt-3.11, and PyQt-3.10. 2. supports sip-4.1.1, -4.1, -4.0, sip-3.11, and sip-3.10. 3. supports Qt-3.3.3 downto -2.3.0. 4. based on Qwt-4.2.0. 5. either links with a shared (dll) Qwt-4.2.0 library or links statically with a slightly patched internal version of Qwt-4.2.0.
