Rivett) and a compass plot (contributed by Bryan Scott). Updated
the ThermometerPlot class. Added a new XYDotRenderer for scatter

easier to align the colors in the legend). Added Regression class

tooltips and the event listener mechanism. Richard Atkinson has
incorporated some useful extensions for servlets/JSP developers.... read more
