Hi all, I am announcing PyQwt-0.29.x: fast and easy data plotting with Python and NumPy see http://gerard.vermeulen.free.fr This is a set of Python bindings for the Qt-2.x and Qwt-0.3 (Qt Widgets for Technical Applications) C++ libraries. It allows you to create interactively 2D-plots of lists, tuples or NumPy arrays of Python floats (=C/C++ doubles). Gerard Vermeulen
