Thanks. I wasn't aware that the method no longer existed. I revised my code as indicated in the following segments: TimeSeriesChartGenerator chartgen; SeriesAttributes attrib = new TimeSeriesAttributes; XYSeries series = new XYSeries; series = new XYSeries("Fish", false); series = new XYSeries("Seal", false); chartgen.addSeries(series, null); chartgen.addSeries(series, null); attrib = chartgen.getSeriesAttributes(); However, I'm still not sure how to modify a particular series' attributes in order to change the line color in the plot. Does each entry in the SeriesAttributes array correspond to exactly one time series? If this is so, then I assume that to change the color corresponding to series, the code would read: attrib.reviseColor(Color.blue, 1.0); But this did not work. Maybe SetStrokeColor(Color.blue) should somehow be used instead. I don't know. Any suggestions? Thanks again.
