JFreeChart 0.9.4 Released

A new version of JFreeChart is available now. The latest changes include (copied from the README file):

0.9.4 : (18-Oct-2002) Added a new stacked area chart (contributed by Dan
Rivett) and a compass plot (contributed by Bryan Scott). Updated
the ThermometerPlot class. Added a new XYDotRenderer for scatter
plots. Modified combined and overlaid plots to use the series colors
specified in the sub plot rather than the parent plot (this makes it
easier to align the colors in the legend). Added Regression class
for linear and power regressions. BasicTimeSeries can now
automatically drop "old" data. Some clean-up work in the code for
tooltips and the event listener mechanism. Richard Atkinson has
incorporated some useful extensions for servlets/JSP developers.

Ran Checkstyle and corrected issues reported for most classes.
Checkstyle is a free utility that you can download from:


Fixed bugs and updated documentation.

API changes include:
- added tickMarkPaint to Axis constructor (also affects subclasses);
- added getLegendItems() to Plot, and deprecated getLegendItemLabels();
- added getLegendItem(int) to XYItemRenderer and CategoryItemRenderer.
- most 'protected' member variables have been changed to 'private'.
