Dave,

Could we get some more time to finish testing before you release 1.0.0-FINAL? One week between the RC and the FINAL is not very long. I think there is a bug in the StackedXYAreaRenderer that is producing some strange results, but I have not been able to track it down yet.

Can you use SVG instead? The vector nature of the format would make it a lot easier.

I do not have a particular problem with the change. But do you have a particular reason why you could not just change the java.io.tmpdir using System.setProperty(...)? Do you particularly need your charts stored in a different temporary directory to other temporary files? If you do not need the Disp...

I think this encoder works very slow. You really need to justify statements like that. How slow? What size of chart? etc. I've done some benchmarking with a 500x300 stacked area chart with 3 series and 15 points per series producing a PNG file of around 15KB. On a 1.6GHz P4 the time to encode the P...

Everything is in CVS, so you can get hold of it from there. You can either use anonymous checkout using a CVS client or pick up the files using ViewCVS - http://cvs.sourceforge.net/viewcvs.py/jfreechart/.

Just implement another class which implements XYToolTipGenerator and use that instead. You can use the TimeSeriesToolTipGenerator as a template.

Do you mean the ToolTips or the Labels? If it is the labels you are trying to get rid of try
Regards,

Passing the ChartRenderingInfo object basically tells the Renderer to collect information relating to ToolTips and URLs. Collecting the tooltip and URL information is pretty memory / processor intensive, so if you do not need them using the shorter method signatures speeds up the rendering quite sig...

Try right clicking on the WAR file link and clicking "Save target as" or whatever looks a likely option in your browser. In a default Tomcat installation you can drop it in the webapps directory and then start Tomcat and it will deploy automatically to /jfreechart-sample. Check you servlet engine lo...

Do you have a servlet definition and mapping setup in your web.xml file? <servlet> <servlet-name>DisplayChart</servlet-name> <servlet-class>org.jfree.chart.servlet.DisplayChart</servlet-class> </servlet> <servlet-mapping> <servlet-name>DisplayChart</servlet-name> <url-pattern>/servlet/DisplayChart</...

Sounds like you have a mismatch between a web based application and a normal X-Windows style application. Better to stick on one or the other. Either have the servlet generate the chart and return it over the HTTP connection or have the other clients launch Swing applications and generate their own ...

The Log4J messages can be ignored, they just mean you haven't enabled anywhere to log the messages. The latest version of JFreeChart (0.9.20) doesn't use it so if you upgrade (API changes are minor) the message will go away. Try adding some of your own logging to find out which part of the chart gen...

There are methods in the ChartUtilities class for writing directly to an OutputStream - like response.getOutputStream(). However I would consider add some logging messages to benchmark your code to confirm where the bottleneck is before doing too much work. You may find the cost of writing the chart...

Here is a critical section from ImageMapDemo3 that you may have missed. final ChartRenderingInfo info = new ChartRenderingInfo(new StandardEntityCollection()); final File file1 = new File("xychart100.png"); ChartUtilities.saveChartAsPNG(file1, chart, 600, 400, info); Unless you pass ChartRenderingIn...

Take a look at BarChartDemo3. It may help you in solving your problem.
