Check the TimeSeries API. You can either set maximum item age with setMaximumItemAge (older will be automatically removed) or maximum item count with setMaximumItemCount . That might help you. Hi, series1.setMaximumItemCount(400); works but series1.setMaximumItemAge((long)xAxis.getLowerBound()); ha...

So I tested the application over night by adding a lot of records (time, value).
With 248340 records I got a Java heap space OutOfMemory,

So has anyone an idea what can I do?

Thanks,

Thanks a lot for your help, All the...

I don't know. TracePanelTimeSeries is not a JFreeChart class, so I don't know what it does. Morning, thats my TracePanelTimeSeries, but I don't think that class is the problem, public final class TracePanelTimeSeries extends TimeSeries { private String name; private int lineCnt; private XYItemRende...

My guess is that you've called setTickUnit() for the DateAxis somewhere in your code, using a tick size that is very small (bearing in mind that the DateAxis measures in milliseconds). That would cause the DateAxis (if the range is longish - say months or years) to create a very large number of tic...

DateTick

Hello, I have a problem with the java heap memory and the class DateTick, respectively. First all TracePanelTimeSeries series are cleared (first code) and than new data is set into the series (second code). My problem now is that if I do this for example the 3. or 4. time, the profiler show me, that...

My question now is, how is the easiest way to recognize the end of the line (data), is there a listener or mus...

chartChanged invokes twice

Hello, I use the class XYSeriesDemo1 and I added a linstener to the JFreeChart- panel (see at the bottom). I recognized that if I zoom into the JFreechart- panel, the method chartChanged is invoked twice instead of once. My problem is that if somebody zooms into the JFreechart- panel, I load data fr...
