Bugs item #2794683, was opened at 2009-05-21 00:52 Message generated for change (Tracker Item Submitted) made by jocaf You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=115494&aid=2794683&group_id=15494 Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: General Group: 1.0.x Status: Open Resolution: None Priority: 5 Private: No Submitted By: Jocafi Brazil (jocaf) Assigned to: Nobody/Anonymous (nobody) Summary: SegmentedTimeline (1.0.13) freezes application Initial Comment: JFreechart version 1.0.13 has problems using the class org.jfree.chart.axis.SegmentedTimeline when a chart uses a period over one year (more than 250 records, for example). The application freezes in this version, while using jfreechart-1.0.11 or earlier it does not freeze. Using few records it does not freeze at all. I changed the example class "CandlestickChartDemo1" to reproduce the error. See the ZIP file in attachment. Change the lines of the method createDemoPanel() to force or not the bug. Thanks in advance !

Just had a quick look at your demo. I can reproduce the bug, when using the line with createDataSetIBM() for dataset creation. It seems the bug is triggering with 63 or more records in the dataset. 62 records works fine for me. The freezing seems to occur in DateAxis.refreshTicksHorizontal(). There is a loop with the following code: while (tickDate.before(upperDate)) { // could add a flag to make the following correction optional... tickDate = correctTickDateForPosition(tickDate, unit, this.tickMarkPosition); [...] At some point, each iteration in the loop leads to the same tickDate, which results in an endless loop. I don't know what correctTickDateForPosition() does or what the intention of the comment just above is. Probably David should have a look at it. I'm not going to do any more debugging at this point, sorry. hth anyway, - martin ---------------------------------------------------------------------- Comment By: Jocafi Brazil (jocaf) Date: 2010-04-28 07:26 Message: More than one year has passed and nothing has been done to fix this bug.

Best regards, Jocafi Brazil ---------------------------------------------------------------------- Comment By: walker (walkeros) Date: 2010-06-10 22:53 Message: The number of data does not have direct impact on this error. The problem occures evactly when the charts decides to display the data on x axis in months instead of days. Witout patching the source code there are few things that you might do to avoid the instant loop: 1) allow only days on x axis: DateAxis dateaxis = (DateAxis)xyplot.getDomainAxis(); dateaxis.setTickUnit(new DateTickUnit(DateTickUnitType.DAY, 1)); However for big number of data this is not good solution, but you may try it so that you see that this is really a problem. 2) enforce date caluculation basing on end of the period: DateAxis dateaxis = (DateAxis)xyplot.getDomainAxis(); dateaxis.setTickMarkPosition(DateTickMarkPosition.END); This should work and seems fine solution unless you need to display the Date including hours (since this will probably try do display the last milisecond of the period) Warning: For me this solution works fine, however this does not really fix the problem (as the solution number 1 does) It just minimises a lot the possibility that DateAxis.correctTickDateForPosition() will constantly roll the date to the same time. BTW: I seems to understand the problem and the correct solution for this. So maybe please contact me in case you feel you really need the solution and if I recive few request , I'll try to patch the code and commit it (unless of course other folks want to commit their solutions first ;)) ---------------------------------------------------------------------- Comment By: Juan Vallejos (juanvallejos) Date: 2010-05-26 05:20 Message: I modify "correctTickDateForPosition".
