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 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 platforms (practically any platform supported by Qt and Python). The home page of PyQwt is http://pyqwt.sourceforge.net. PyQwt-4.2 is a maintenance release to keep up with the recent releases of PyQt-3.14 and its code generator SIP-4.2. PyQwt-4.2 supports: 1. Python-2.4 downto -2.1. 2. PyQt-3.14 downto -3.10. 3. SIP-4.2 downto -4.0, and SIP-3.11 downto -3.10. 4. Qt-3.3.4 downto -2.3.0. 5. Qwt-4.2.0. Have fun -- Gerard Vermeulen
