After more than 4 years, there's finally a new
Cewolf release! It's based on the various "cewolf-1.1-ulf" releases that have been available from my web site at
http://www.ulfdittmer.com/code/cewolf.html, and incorporates lots of bug fixes and enhancements over 1.0, both from myself and numerous other contributors. The release notes has all the details, but the big issues are:
- All Cewolf objects are Serializable - there'll be no more exceptions when they're put into sessions.
- A lot of new postprocessors have been added, so if certain charts don't quite look the way you'd like them, check out the de.laures.cewolf.cpp package - it contains numerous classes that tinker with charts. There's even one that puts annotations (labels and arrows pointing to specific data points) on the chart.
- Several new chart types are available: spline, spiderweb, dial, compass, thermometer, stackedhorizontalbar3d
- The
JSP expression language (EL) can now be used for parameter values - scriptlets are no longer necessary.
- Lots of bug fixes, performance and HTML improvements, and additional attributes for setting chart options.
Be sure to download the example web app as well - it shows all chart types as well as many of the options and postprocessors in action. It includes everything you need to get started with using cewolf in your web app.
