I saw that the changes have already been copied over to the branch in the svn repository, therefore I checked out the source code, compiled jfreechart and reran the unit test. Generating a CategoryChart with 5500 data points now takes about 15 seconds on my laptop. Creating a similar chart on my mor...

DefaultKeyedValues does not scale well

Among other methods in this class the getIndex(Comparable key) method iterates over the data list to find the matching row. This does not scale well with category charts that contain several thousands data points. I wrote a unit test that uses the LineAndShapeRenderer to create scatter plot and prof...

Just for your info: I tried the Orson libraries with latest daily builds of NetBeans 6.0, but without success: first an NPE when I drop a JLineChart on a JFrame and then next one when I try to save the form (and I finally cannot save it).

You have to add the JFreeChart libraries to your project's dependencies.

I have tested adding a JLineChart to a JFrame using NB 6.0 successfully.

Richard,

thanks for taking this up so quickly!
I am looking forward to the next release :-)

(By the way, the javascript library I am using to display tooltips is domTT, http://www.mojavelinux.com/forum/viewtopic.php?t=127).

Jeremy, the options I posted work for me on a Tomcat/Solaris 2.8 box. They worked with Tomcat 3.2.1 and now they work with 1.4.0. Sorry, I cannot give you more info on this (no Weblogic available). Most probably, moving to 1.4.1 would be the best solution, but I guess, that road is blocked in your c...

The API changes are inconvenient (I have gone through the same process, 0.9.8 -> 0.9.9 -> 0.9.10), but they have simplified the API itself a lot.

As long as the library is improving significantly with each release, I don't mind.

My opinion.

You have to add the libraries to the boot classpath, not the normal classpath, and then pass additional options to the JVM, like: -Xbootclasspath/a:${PJALIB}/pja.jar -Dawt.toolkit=com.eteks.awt.PJAToolkit -Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment -Djava2d.font.usePlatormFont=fal...

Image Map generation not flexible enough

JFreeChart needs a small framework, that allows developers to plug in custom image map generators, like that in jCharts. Looking first through the developer guide, that I bought, and then through the source code, I detected, that, in order to use a tooltip library different from overlib, I actually ...
