Re: hi guy,i have a question,please help me!
I would take a look at SimpleHistogramDataset, it is a different dataset implementation that allows for updates.

Re: XYDataSeries does not update
At some point (I think version 1.0.14) I changed the getDataItem() method to return a clone of the object to make it harder for the XYSeries to have its data values changed without triggering a SeriesChangeEvent.

Re: J free Chart
What is the exact error, because that message doesn't make a lot of sense. In any case, I would recommend updating to JFreeChart 1.0.19 or 1.5.0.

Re: hi guy,i have a question,please help me!
Better is to make the jump to JFreeChart 1.5.0, then you don't need JCommon at all. But if you must use JFreeChart 1.0.x, then you'll see the JCommon dependency in the pom.xml <dependency> <groupId>org.jfree</groupId> <artifactId>jcommon</artifactId> <version>1.0.24</version> </dependency>

Re: I am a new member and I need help from everyone.
It's possible there was a bug somewhere along the way. The latest version is working, you should try to upgrade to the latest version of JFreeChart or compare the XYSeries and DatasetUtilities classes between the two versions to see what has changed.

Re: hi guy,i have a question,please help me!
The item labels feature doesn't include any automatic way to avoid labels overlapping - sometimes there just isn't enough space. I would suggest that if you need to display data values for every single point in your chart, then perhaps you should just present the data in a table, maybe with a chart ...

Re: JFreeChart for JavaFX - Moving Average takes VERY long time
How is the source series defined? I think there might be a mismatch between the RegularTimePeriod instance used internally by the TimeSeries and the periodCount argument you are using in the call to the method creating the moving average, but it is hard to tell.

Re: Custom colors for scatter plots
This renderer uses a single color in order to maximise performance - once you start changing the color for each data item, you'll have to bear the cost of that state change.

Re: Save as SVG by right click on chartpanel
You need to ensure that the jfreesvg.jar file is on the class path. As long as that is the case, JFreeChart should automatically detect it and provide the option to export charts to SVG format.

Re: Customizing Popup menu for PolarChartPanel
For the PDF and SVG export options, there is some code in ChartPanel that is auto-detecting if OrsonPDF and JFreeSVG are on the class path, and adding the menu items only if they are there. It looks like the PolarChartPanel class skips this code entirely, so there is some work to do to add these. I'...

Re: Line Annotation does not draw
The coordinates that you pass to the XYLineAnnotation constructor need to be specified in data space (that is, values relative to the chart's axes) not in screen space.

Re: Chart Appears as red colour in android mobile acrobat Re
I would guess that this is a bug in the PDF viewer application, not something related to JFreeChart.

Re: Please help: tooltip stop working on rotated plot
Can you post a demo that is self contained? That is, one that I can copy and paste, compile and run. Then I will have a better chance to debug the issue. Also, which version of JFreeChart do you see this issue with?
