PyQwt is a set of Python bindings for the Qwt C++ class library which extends the Qt framework with widgets for scientific and engineering applications. It provides a widget to plot 2-dimensional data and various widgets to display and control bounded or unbounded floating point values. PyQwt addresses the problem of integrating PyQt, Qt, Qwt, NumPy and optionally SciPy. Look at the Command Line Interface (CLI) examples and the Graphical User Interface (GUI) examples to get an idea of what you can do with PyQwt. WWW: http://pyqwt.sourceforge.net/
