SCaVis is a takeover of jHepWork (1995-2013). SCaVis is fully compatible with the jHepWork v3.9.
This tutorial discusses the community "desktop" IDE. In addition, SCaVis includes IDE with plotting canvaces 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 "The art of scientific computation: Introduction to data analysis using Jython scripting and Java". At present, this is the most complete, up-to-date textbook describing Jython scripting and SCaVis.
There is also a growing SCaVis online manual. Also look at the tutorial: Data Analysis and Data Mining Using Java, Jython and SCaVis (Java.net, 2011). You may also look at Help API which organizes the topics in form of tree.
