May be you can create OHLCDataset as CandleStick Dataset.

Example:

OHLCDataset ohlcDataset=createDataCandle();
JFreeChart jfreechart1 = ChartFactory.createCandlestickCha("Candlestick Demo", "Time", "Value", ohlcDataset, true);

public OHLCDataset createDataCandle()
{
Date adate[] = new Date[a.getVolumeArray().length];
double ad[] = new double[a.getVolumeArray().length];
double ad1[] = new double[a.getVolumeArray().length];
double ad2[] = new double[a.getVolumeArray().length];
double ad3[] = new double[a.getVolumeArray().length];
double ad4[] = new double[a.getVolumeArray().length];
int i = 1;
byte byte0 = 2;
for(int is=0;is<a.getVolumeArray().length;is++)
{
adate[is] = new Date(a.getDateArray()[is]);
ad[is] = a.getHighPriceArray()[is];
ad1[is] = a.getLowPriceArray()[is];
ad2[is] = a.getOpenPriceArray()[is];
ad3[is] = a.getClosePriceArray()[is];
ad4[is] = a.getVolumeArray()[is];
}
return new DefaultHighLowDataset("Series 1", adate, ad, ad1, ad2, ad3, ad4);
}

Hope this can help you. Good Luck.
