I have an application which updates a variable about between 5 to 50 times a second and I am looking for some way of drawing a continuous XY plot of this change in real-time. Though JFreeChart is not recommended for such a high update rate, many users still say that it works for them. I've tried using this demo and modified it to displa...
Hello, I'm trying to display data on a XYBarChart using JFreechart. The chart should display points in time along with a count. Thus, if the user chooses Jan 25 and March 25th as the range, the chart should display data between those dates in certain intervals: if the user chooses HOUR, then I create a collection of every hour from Jan ...

Hi, I'm working with JFreeChart to plot several TimeSeries charts. It seemed to be working fine, but as of today, all the graphs seem to flicker and are randomly glitching making them impossible to see. If I minimize and maximize, the issue gets fixed for a few seconds until the next update or mouse click. Does anyone have an idea about...
I'm adding Internationalization into a Tapestry web-app which uses Jasper Reports to generate normal tabular reports and also charts and graphs via JFreeChart. Using the Jasper REPORT_LOCALE parameter, I can set the Locale for Jasper reports and this works beautifully for the tabular reports but it doesn't work for the JFreeChart report...
I am creating a pie chart using a JRBeanCollectionDataSource. I create that with an ArrayList whose contents are ordered specifically. When JasperReports uses JFreeChart to generate the Pie, the content order is remixed in no apparent ordering. JasperReports 3.5.3 JFreeChart 1.0.11 Java 1.6 ...
I'm using a XYPlot to show a line graph with 1 or more lines in it. I have it combined with a listener pattern so it can receive updates: if so, it removes the lines using a dataset.removeAllSeries() (dataset is of type XYSeriesCollection) call, and then adds the new lines using dataset.addSeries(...) However, a new graph with new lines ...
In this demo application, XYPlot is drawn with dynamic data. With every new data the graphic slides to left dynamically. But the problem is if you zoom in or zoom out on XYPlot the graphic stops sliding and new data can not be seen on XYPlot. Is this a bug for JFreeChart or is it default behaviour for XYPlot ? ...

We are using JFreeChart to make XY plots and we have a feature request to do a crosshair that moves along with the mouse and highlights the data point that most closely maps to the x-value of the mouse. You can see a similar example at Google Finance - http://www.google.com/finance?q=INDEXDJX:.DJI,INDEXSP:.INX,INDEXNASDAQ:.IXIC. Those ...
