I’m trying to extract TimeSeriesAttributes in order to set the line color in a time-series by using setStrokeColor(). I followed the suggestions in: MASON-INTEREST-L Digest - 24 Aug 2009 to 26 Aug 2009 (#2009-25) I am using the following sample code segments: TimeSeriesChartGenerator chartgen; TimeSeriesAttributes attrib; XYSeries series[]; series[1] = new XYSeries("Fish abundance", false); series[2] = new XYSeries("Seal abundance", false); chartgen.addSeries(series[1], null); chartgen.addSeries(series[2], null); TimeSeriesAttributes attrib = (TimeSeriesAttributes) chartgen.getSeriesAttributes(1); attrib.setStrokeColor(Color.blue); However, when I try to extract the TimeSeriesAttributes in the line before last, I get the following error: The method getSeriesAttributes() in the type ChartGenerator is not applicable for the arguments (int) Is this the correct way to change the line color?
