初めて質問させていただきます。

JFreeChartでローソク足の株価と折れ線の移動平均線を
表示するグラフを作りたいのですが
ローソク足のグラフと折れ線グラフを
一緒にすることができません。
setDatasetのところで
java.lang.ClassCastException: org.jfree.data.time.TimeSeriesCollection
というエラーが生じてしまいます。

どなたか分かる方がいらっしゃいましたら
教えていただけないでしょうか。

========================================================

//データ設定
Date[] date = new Date[5];
double[] high = new double[5];
double[] low = new double[5];
double[] open = new double[5];
double[] close = new double[5];
double[] volume = new double[5];


date[0] = DateUtilities.createDate(2005, 10, 4);
high[0] = 5700.0;
low[0] = 4250.0;
open[0] = 4500.0;
close[0] = 4300.0;
volume[0] = 14000.0;

date[1] = DateUtilities.createDate(2005, 10, 5);
high[1] = 5700.0;
low[1] = 4230.0;
open[1] = 5100.0;
close[1] = 4730.0;
volume[1] = 13000.0;

date[2] = DateUtilities.createDate(2005, 10, 6);;
high[2] = 5900.0;
low[2] = 5300.0;
open[2] = 5500.0;
close[2] = 5800.0;
volume[2] = 8000.0;

date[3] = DateUtilities.createDate(2005, 10, 7);
high[3] = 6100.0;
low[3] = 4900.0;
open[3] = 5100.0;
close[3] = 5400.0;
volume[3] = 23000.0;

date[4] = DateUtilities.createDate(2005, 10, 8);
high[4] = 7000.0;
low[4] = 5000.0;
open[4] = 5600.0;
close[4] = 6300.0;
volume[4] = 15000.0;


OHLCDataset dataset = new DefaultHighLowDataset("Series 1", date, high, low, open, close, volume);
JFreeChart chart = ChartFactory.createCandlestickChart("Sample Candlestick Chart",
"Time", "Value", dataset, true);


TimeSeries s1 = new TimeSeries("移動平均", Day.class);

s1.add(new Day(4,10,2005), 6500);
s1.add(new Day(5,10,2005), 6800);
s1.add(new Day(6,10,2005), 7000);
s1.add(new Day(7,10,2005), 6500);
s1.add(new Day(8,10,2005), 7800);

TimeSeriesCollection dataset2 = new TimeSeriesCollection();
dataset2.addSeries(s1);
dataset2.setDomainIsPointsInTime(true);

XYPlot plot=chart.getXYPlot();
plot.setDataset(1,dataset2);
