The Py4dat/PyDVT Home Page 

Introduction
	PyDVT is a set of  powerful data visualisation widgets, and data abstraction frameworks written by Alexandre Gobbo during a short stay at ESRF. The original PyDVT home pages are accessible on the ESRF web pages. There you will find a lot of good documentation for using PyDVT in your applications. You will also find the original packages, availables for many platforms. Py4dat is an application built on PyDVT that allows data manipulation. It has also a window, called MLab, where you have a sort of python shell by which you can interact with py4dat from the command line.  You can, by this mean, import whatever python module you want, manipulate data, write formulas, functions, execute them to operate on datas, and display graphically data in many formats. You can download this package from the pydvt project pages at sf.net.
Installation of Py4dat
	If you are not interested with the MLab fonctionalities fo Py4dat you can grab the PyDVT packages from its original location  on the ESRF web page  Otherwise for Linux (python2.2, pyqt, pyqwt, qt3.xx, Numeric, PIL) : just grab the latest version of the py4dat package archive at sourceforge.net . It contains  both PyDVT widgets and the Py4dat project. Untar the archive. The launching script is  Py4dat/WRAPPERS/py4dat. You have to edit such script and change the variable PACKAGE_HOME to reflect the actual location of the package.
Demo scripts for MLab
	The MLab plugins offer many fonctionalities, the documentation is not rich, however a good way to familiarize with MLab is to try these demos : demo_serialisation.py  showing some graphic features and serialisation demo_filters.pyand the imported module DemoPolygonViewSelectQt.py (which is imported when you execute the demo-filters.py lines). Showing how to cascade several data and View filters. These demo are runned copying and pasting their contents in the MLab window. You can run the demo line by line by pressing simultaneaously <Shift>+<Enter> when the cursor is on the line, or a whole set of selected lines always by pressing <Shift>+<Enter>.
