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.... read more
