All,
I am using the following combined Segmented Timeline to plot historical commodity prices. The requirement is to show data from Monday to Friday between 8 PM to 4 PM. The implementation involved a combination of Segmented Timelines.
SegmentedTimeline timeline = new SegmentedTimeline(SegmentedTimeline.FIFTEEN_MINUTE_SEGMENT_SIZE, 80, 16); // 15 min timeline from 8 PM to 4 PM that excludes 16 segments
timeline.setStartTime(SegmentedTimeline.firstMondayAfter1900() + 80 * timeline.getSegmentSize() - TimeZone.getDefault().getDSTSavings()); // 8 PM is the start time
timeline.setBaseTimeline(SegmentedTimeline.newMondayThroughFridayTimeline()); // Mon - Fri Segmented Time line is the base time line
dateAxis.setTimeline(timeline); // Sets the time line on the axis.
Working: I am not seeing the gaps between 4 PM - 8 PM on the charts as expected.
Not Working: Seeing the gap from 4PM on Fri to 6 PM on Sunday. I was hoping that Sat-Sun will not be shown on the chart.
As a side note, we currently have data from 6PM to Mid night for Sunday. Does it have anything to do with not hiding Sat-Sun from the charts?
Please advice.
Thanks,
Amar

The problem is still not solved. New release 1.0.15 doesn't include the correction. Can you provide some solution for the problem?
Thanks.
Thanks.

There's nobody working on this code at present. I intend to remove it from version 2 of JFreeChart because it causes too many issues and has no-one maintaining it.

Re: Segmented timeline plots unexpected Saturday-Sunday
Does it mean that SegmentedTimeline implementation will not be part of jfreechart 2.x?

Re: Segmented timeline plots unexpected Saturday-Sunday
Yes. Either we'll find a better approach to plotting time series data while excluding non-business days, or do without this feature. I've tried in the past to resolve some of the issues with the SegmentedTimeline code, but I wasn't very successful. It's made more complicated by the fact that I didn't write the original code, and I can only work on this stuff part-time. No-one else has come up with a good fix/solution either.
