Abstract:

Warning: The documentation is for the future PyQwt-4.2.3 which is only available from CVS. The download page has links for the latest releases.

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).
