标签: Minor feature enhancements
This release contains various bugfixes and minor
enhancements to JFreeChart. PiePlot labelling has
been enhanced with new curve options and more
robust bounds checking. The BoxAndWhiskerRenderer
now has a maximumBarWidth attribute, and the
XYStepRenderer has a new stepPoint attribute. The
RelativeDateFormat class has new options. There
are new dataset classes (SlidingCategoryDataset
and SlidingGanttDataset) that permit a subset of
categories to be plotted and allow charts based on
these datasets to simulate scrolling. There is a
new ShortTextTitle class.
