JSF Chart Creator

[cagatay_civici]

Dear JFreeChart Community,

I'm pleased to announce that JSF ChartCreator's new version 1.2.0-M1 is ready, This release contains many new features and several bug fixes.

* Provided an optional configuration to switch between a servlet and a phaselistener as the generator of the charts. This is done so because, a phaselistener can be used in a portlet environment and a servlet can be used when some other lib's phaselistener(like Ajax4JSF) prevents chart's phaselistener from getting called.

* Added a new child component called chartAxis that can be used to customize a single axis.

* Created a renderer for the chart component so users can override it if they want.

* Clickable chart sections; Previous version was supporting custom image maps but this new feature generates automatic image maps for each chart section and users can attach events to be processed when for example a bar is clicked for a bar chart.

* Several bug fixes.

Much more information can be found at ChartCreator's home page at;

Thanks for the new version of the ChartCreator!

Unfortunately I get an UnsupportedClassVersionError with JBoss 4.0.5.GA and Java 1.5.0_06. Did you compile the release for Java 1.6 only?

Ooops:( I guess I haven't configured the ant taks's compiler after upgrading my jdk to 6. I'm going to fix this asap, thanks for the catch.

I've fixed the jvm dependency issue and made a M2 Release that's compatible with 1.4+.

Hi Cagatay.
I sent you the additions that I made to your component to allow for alternative legends (the legendContainer attributes) for pie charts.

Did you get it and have you had a chance to implement them into your source?

[cagatay_civici]

Hi Chris,

No, I haven't add your patches yet but probably they'll be in the next release.

Thanks,

Cagatay

Hi,

There's an example configuration in sample web application and it's also documented in the chartcreator documentation homepage.

I've fixed the jvm dependency issue and made a M2 Release that's compatible with 1.4+.

I still get the same error when I try to deploy the example webapp on Bea Weblogic Express 9.2.

Seems the issue is still there, ok I'll take care of this once and for all. The next release will be 1.2.0, no more rc's.

[cagatay_civici]

I've deployed the example webapp of chartcreator online,

Version 1.2.0 is released, it contains several minor fixes and hopefully the jdk version issue is gone now:) As a reminder online demo is at

Hi. I just downloaded the new release for ChartCreator... Thanks!

I'm trying to get a simple chart work into an IBM portlet. Is it possible? I just copied your example, for the jsf-comp/Chart creator page. But it doesn't work in my portlet. I followed the instructions...but chart doesn't appear. I copied and pasted your <c:chart> code into my portletview jsp.

my bean has your code for getPieDataSet. Also, I tried changing the context-param to true and false...still doesn't appear...

Thanks for your help!!

Hi,

Can I customize how a chart looks like ? for example, for a 2D line chart can I set the weight of the line and the points to be visible and a tooltip on the points ?

thanks,
Mihaela.
