[Jchart2d-release] JChart2D 2.0.0 released

[Achim W. <Ach...@gm...>]

Dear jchart2d user,

this is the first mail to the list as it is the first time a release of 
jchart2d has been made and the subscriber list is not empty.

A new major version of jchart2d has been released. As this version 
includes major changes in the code that require refactoring the version 
number as advanced in the first position: from 1.1.1 to 2.0.0.

Features:
The new version adds new UI controls such as coordinate tooltips for the 
chart, selectable logarithmic scaling (base e, base 10) for each axis, 
menu bar controls, experimental zooming in the X dimension, and an 
improved popup menu. A bug related to ringbuffered traces and some UI 
bugs (update view upon model change) were fixed.

Refactoring:
The whole package structure has changed to prefix - match a name of a 
registered domain: info.monitorenter. Furthermore subpackages for 
implementations have been introduced. This allows to overview the API 
that remains in info.monitorenter.gui.chart.
Developers who already integrated JChart2D in products will have to 
perform various refactoring tasks because of new package naming. Tip: 
Within eclipse hold down Shift, Ctrl and 'o' to change the package imports.

Changelog:

Almost all new features are results of contributions or feature 
requests. Thanks for those, please continue to improve jchart2d.

kind regards,

Achim Westermann
