The add() method in the XYSeries class sorts by x position, so you might want to subclass it to override that behaviour. "XYChartEntity"s give you the dataset, series and item which was selected. So you could store any metadata in your dataset (or in a separate list). Or you could subclass the rende...

I don't know about the legend (I've never needed to use a legend in my charts), but everything else you've mentioned is possible. You can set the Shape and Paint for individual data points, which covers your "circle or square" requirement. There's a "ChartEntity" concept, which maps shapes that have...

I've implemented this, it's one of the many patches I'll be submitting soon.

Unfortunately there are so many modifications I've made to JFreeChart that my application depends on, it would take a lot of work to run it against the original source for comparison. It might be an order of magnitude faster than it was... but that's just a guess. I'm submitting the patches one at a...

I don't really understand what you want with the tooltips, but I hope this helps with the JScrollPane-like behaviour:

If you search the forums, there's at least one other example of axis-scrolling code available.

Following up my own message, in case someone's interested in this... I haven't submitted my patches yet, but I have had quite a bit of success: Rendering 10 years of day data for MSFT on NASDAQ (around 2800 data items) simultaneously as candlesticks, bars, and two lines (in a combination of overlaid...

Would you mind posting your latest code? I'll try to see what's going wrong.

I think that XYBarRenderer requires an IntervalXYDataset, so you'll need to implement that interface in your dataset.

And another:

I think you want to use an XYBarRenderer.

The solution I would use would be to define my own renderer, and use the data items as inputs to the function I want to plot.

Yes. Use a DateTickUnit, and specify a DateFormat. For example: TickUnits units = new TickUnits(); units.add(new DateTickUnit(DateTickUnit.MONTH, 1, new SimpleDateFormat("MMM-yyyy"))); units.add(new DateTickUnit(DateTickUnit.MONTH, 2, new SimpleDateFormat("MMM-yyyy"))); units.add(new DateTickUnit(Da...

It's not perfect, it's not generic, and it may not work for you, but here's what I'm using for scrolling: import java.awt.*; import java.awt.event.*; import javax.swing.*; import org.jfree.chart.*; import org.jfree.chart.axis.*; import org.jfree.chart.event.*; import org.jfree.chart.plot.*; import o...

Can you please post some more code, which shows the data that you're using (and can preferably be compiled and run to see the problem)? The construction code doesn't have any problems that are obvious to me, though I don't know what the "com.analysis.util.CustomIndicators" class does.
