JSF Chart Creator Component Based on JFreeChart

[honza]

I figered it out: The dataset must be of type XYDataSet (interface), e.g.: DefaultXYDataset.

[honza]

I would like to ask how to pass a parameter to the JFreeChart?
I have this code:

Code: Select all

<c:chart datasource="#{Page2.dataset}" id="chart" type="xyline"/>

This component is in <h:dataTable> component. I would need to pass a parameter to the chart on every dataTable row.

I tried this, but it does not work:

Code: Select all

<c:chart datasource="#{Page2.dataset}" id="chart" type="xyline">
             <f:attribute name="longInput" value="300" />
         </c:chart>

I followed steps as described in the web site "installation and configuration" but something wrrong.
"http ://sourceforge.net/projects/jsf-comp" causes error when I start my web project with tomcat server.

Hi!

i've implemented Chart Creator in my JSF-Site.
It works good.
I'm using Gantt as chart type.

But I have a big problem.

I want to create individual tooltips.
By now they're looking like: 01.01.2001 - 04.02.2001
But I want to use my own style and information.

Is it possible to create them?
Normally i can do this with:

Code: Select all

public String generateToolTip(CategoryDataset dataset, int series, int index) {
   return seriesNames[series];
}

It's very important.
Thank you for helping!
