Hi
i want to use jfreechart for plotting graph
i have timestamp on x axis and values on yaxis.
is there support for timestamp?
i thought of using timeperiod
as the above timestamps are generated at given interval like
for every 5 minutes or 5 seconds or 1 hour.
i got errors any one help me please
TimeSeries.add(...) inconsistent time period class .
code ..from changing ..JFreeChartDemo2
BasicTimeSeries series = new BasicTimeSeries("Random Data");
Day current = new Day(1, 1, 1995);
double value = 100.0;
//java.util.Date time=new Date();
Minute mn=new Minute(10, current);
// Millisecond ms=new Millisecond(time);
for (int i=0; i<10; i++) {
try {
value = value+Math.random()-0.5;
series.add( mn,new Double(value));
mn = (Minute)mn.next();
}
catch (SeriesException e) {
System.err.println("Error adding to series"+e);
}
}
XYDataset data = new TimeSeriesCollection(series);
JFreeChart chart = ChartFactory.createTimeSeriesChart ("Test", "Day", "Value", data, false);
JFreeChartFrame frame = new JFreeChartFrame("Test", chart);
frame.pack();
frame.setVisible(true);
}
Thanks in advance..
