关于jfreechart动态 时间轴的疑问.

Question

在动态的折线图里面的时间轴显示是系统的时间.
现在我想把他改成从00:00:00开始的时间，应该怎么做？使用setMinimumDate？好像设置完之后动态图就不走了．哪位朋友指明一下，先谢了.

很简单的动态图TimeSeriesCollection timeseriescollection = new TimeSeriesCollection();
timeseriescollection.addSeries(total);
BasicStroke basicstroke = new BasicStroke(2.0F, 0, 2); XYLineAndShapeRenderer xylineandshaperenderer = new XYLineAndShapeRenderer(true, false);
xylineandshaperenderer.setSeriesPaint(0, line1Color);
xylineandshaperenderer.setStroke(new BasicStroke(3F, 0, 2)); chart = ChartFactory.createTimeSeriesChart("", "", "Value", timeseriescollection, false, false, false);
XYPlot xyplot = chart.getXYPlot();
xyplot.setBackgroundPaint(Color.BLACK);
xyplot.setDomainGridlinePaint(Color.GREEN);
xyplot.setRangeGridlinePaint(Color.GREEN);
ValueAxis valueaxis = xyplot.getDomainAxis();
valueaxis.setAutoRange(true);
valueaxis.setFixedAutoRange(60000D);
valueaxis.setVisible(true);
valueaxis.setAxisLinePaint(Color.yellow);
valueaxis.setLabelPaint(Color.yellow);
valueaxis.setAutoTickUnitSelection(false); calendar = Calendar.getInstance();
// calendar.set(Calendar.HOUR_OF_DAY, 0);
//calendar.set(Calendar.MINUTE, 0);
//calendar.set(Calendar.SECOND, 0);
// ((DateAxis) valueaxis).setMinimumDate(calendar.getTime());
((DateAxis) valueaxis).setTickUnit((new DateTickUnit(DateTickUnit.SECOND, 10, new SimpleDateFormat("HH:mm:ss"))));
valueaxis = xyplot.getRangeAxis();
valueaxis.setRange(-200.0D, 200);
valueaxis.setVisible(false); ChartPanel chartpanel = new ChartPanel(chart);
chartpanel.setPopupMenu(null);
chartpanel.setMouseZoomable(false);
add(chartpanel, BorderLayout.CENTER);然后再：total.addOrUpdate(new Second(), d);如何让时间是从00:00:00,而不是系统时间显示在时间轴上?
