Problem with timeline

[noriandir]

I'm having some problems with the timeline usage.
When I use it, the window that should have the chart is blank. If I don't use it, it works fine but all weekends and holidays appear.

I'm using a SegmentedTimeline and for the holidays I'm adding them to the exception list.

here's the code:

Code: Select all

/**

 */
@SuppressWarnings("serial")
public class YardChart extends JFrame {
	private int _height = 800;
	private int _width = 400;
	private JFreeChart _chart;
	private YardCalendar _calendar;
	private static SegmentedTimeline _timeline;

	public JFreeChart getChart() {
		return _chart;
	}

	public YardChart(String market, String stockSymbol, String alarm) {
		super("Yard");
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		//Creates and imports the data into the calendar
		_calendar = new YardCalendar(market);
		_calendar.importASCII("/home/ciccio/CALENDAR/"+market.toUpperCase()+"/Calendar.txt");

		_timeline = SegmentedTimeline.newMondayThroughFridayTimeline();
		
		DateAxis    domainAxis       = new DateAxis("Date");
		NumberAxis  rangeAxis        = new NumberAxis("Price");
		CandlestickRenderer renderer = new CandlestickRenderer();
		DefaultOHLCDataset dataset   = getDataSet(stockSymbol, alarm);

		//Do some setting up, see the API Doc
		renderer.setSeriesPaint(0, Color.BLACK);
		renderer.setDrawVolume(true);
		rangeAxis.setAutoRangeIncludesZero(false);
		domainAxis.setTimeline(_timeline);

		XYPlot mainPlot = new XYPlot(dataset, domainAxis, rangeAxis, renderer);

		//Now create the chart and chart panel
		_chart = new JFreeChart(mainPlot);
		ChartPanel chartPanel = new ChartPanel(_chart);
		chartPanel.setPreferredSize(new Dimension(_height, _width));
		setContentPane(chartPanel);

		this.setTitle(alarm);
	}
	protected DefaultOHLCDataset getDataSet(String stockSymbol, String alarm) {
		//This is the dataset we are going to create
		DefaultOHLCDataset result = null;
		//This is the data needed for the dataset
		OHLCDataItem[] data = getData(stockSymbol,alarm);

		//Create a dataset, an Open, High, Low, Close dataset
		result = new DefaultOHLCDataset(stockSymbol, data);

		return result;
	}

	protected OHLCDataItem[] getData(String stockSymbol, String alarm) {
		List<OHLCDataItem> dataItems = new ArrayList<OHLCDataItem>();
		try {
			String path = "/home/ciccio/SIMULAZIONI/"+stockSymbol+"/CARTELLE/DBINFO/"+alarm+"/";
			FileInputStream candleValues = new FileInputStream(path+"GuiValue.txt");
			FileInputStream dateValues = new FileInputStream(path+"Date.txt");

			DataInputStream in = new DataInputStream(dateValues);
			BufferedReader br = new BufferedReader(new InputStreamReader(in));

			String startDate = br.readLine().substring(0, 6);
			in.close();

			//NOTE: the file year format is yy instead of yyyy, so 2000 is needed to be added
			int startYear = 2000+Integer.parseInt(startDate.substring(0, 2));
			int startMonth = Integer.parseInt(startDate.substring(2, 4));
			int startDay = Integer.parseInt(startDate.substring(4, 6));

			ListIterator<YardDay> itr = _calendar.findPosition(startYear, startMonth, startDay);


			in = new DataInputStream(candleValues);
			br = new BufferedReader(new InputStreamReader(in));

			String inputLine;
			br.readLine();
			YardDay calendarDay = itr.next();
			while ((inputLine = br.readLine()) != null) {
				System.out.println("input:\t\t\t\t"+inputLine);

				SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd");
				Date date = formatter.parse(calendarDay.getYear()+"/"+calendarDay.getMonth()+"/"+calendarDay.getDay());

				//skips Weekends
				while(calendarDay.isWeekend()){
					calendarDay = itr.next();
					date = formatter.parse(calendarDay.getYear()+"/"+calendarDay.getMonth()+"/"+calendarDay.getDay());
				}
				
				//add holidays to the candle exception list
				while(calendarDay.isHoliday()){
					_timeline.addException(date);
					calendarDay = itr.next();
					date = formatter.parse(calendarDay.getYear()+"/"+calendarDay.getMonth()+"/"+calendarDay.getDay());
				}

				if(calendarDay.isWorkDay()){
					System.out.println(date.toString()+":\t"+inputLine+"\n");

					StringTokenizer st = new StringTokenizer(inputLine, " ");
					NumberFormat nf = NumberFormat.getInstance(Locale.ITALIAN);
					double open     = nf.parse(st.nextToken()).doubleValue();
					double high     = nf.parse(st.nextToken()).doubleValue();
					double low      = nf.parse(st.nextToken()).doubleValue();
					double close    = nf.parse(st.nextToken()).doubleValue();
					double volume   = nf.parse(st.nextToken()).doubleValue();

					OHLCDataItem item = new OHLCDataItem(date, open, high, low, close, volume);
					dataItems.add(item);
					calendarDay = itr.next();
				}
			}
			in.close();
		}
		catch (Exception e) {
			e.printStackTrace();
		}

		//Convert the list into an array
		OHLCDataItem[] data = dataItems.toArray(new OHLCDataItem[dataItems.size()]);

		return data;
	}
}

I've not put the includes so the code is a bit more readable here.

Can anyone help me to solve this?

Thanks


PS: using JFreeChart 1.0.14 and JCommon 1.0.17.

I really didn't understood what you meant by that... =/
