You might experiment with some combination of pan and zoom using setDomainPannable() and setMouseWheelEnabled(), seen here and here. Right-click to see the context menu and control-click to pan (option-click on Mac OS X).
It’s not clear how you are formatting the dates now, but setDateFormatOverride in DateAxis allows you to specify a suitable SimpleDateFormat. If not already available, you should be able to override getShortMonths() in DateFormatSymbols for the Roman numerals. Addendum: For correct localization, it may be easier to do something like this: DateAxis axis = (DateAxis) … Read more
You can get a List of subplots using getSubplots(). To learn which subplot was clicked, examine the ChartMouseEvent that was sent from the ChartPanel, as suggested here. Addendum: Here’s a simple implementation of ChartMouseListener that will show each ChartEntity as it is clicked. ChartPanel panel = … panel.addChartMouseListener(new ChartMouseListener() { @Override public void chartMouseClicked(ChartMouseEvent e) … Read more
This complete example creates a suitable database table in memory, queries it into a JDBCXYDataset and displays the dataset in a scatter plot. Note how the first column becomes the domain, while successive columns become individual series. import java.awt.EventQueue; import java.sql.Connection; import java.sql.Date; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; import java.sql.Statement; import java.util.Calendar; import java.util.Random; … Read more
Most ChartFactory methods include a boolean tooltips parameter. Just look in the source for your factory of choice to see how to instantiate a default tooltip generator suitable for the designated renderer. You shouldn’t need to handle the events yourself. Addendum: As you are using createXYLineChart, an instance of StandardXYToolTipGenerator is supplied by default. The … Read more

Several problems are evident: You never add anything to lines; at a minimum, you’ll need something like this: lines.add(line); Instead of ChartFactory.createXYLineChart(), consider creating a time series: ChartFactory.createTimeSeriesChart(…) The XYDataset returned by createDataset() should be a TimeSeriesCollection to which you add a TimeSeries. In createDataset(), iterate though lines, parse the data fields, and add the … Read more
Use setDateFormatOverride() on the axis with a suitable DateFormat: axis.setDateFormatOverride(new SimpleDateFormat(“HH:mm”));
