Getting started tutorial (3 min movie)

This tutorial discusses the community "desktop" IDE. In addition, DMelt includes IDE with plotting canvases and Jython shell for small-screen devices. This video shows how to use it. Here is another example showing an interactive fit program .


New features included in the jHepWork release 2.2 and above are described in the book Scientific Data Analysis using Jython Scripting and Java. At present, this is the most complete, up-to-date textbook describing Jython scripting and SCaVis.
