Alain Raynaud commented on JBSEAM-3750:
---------------------------------------
I looked at the example in itext, however the timeseries tag is using an empty dataset:
dataset="#{chartseries.dataset}" (in chart.xhtml).
All my attempts at populating the dataset from Java have failed. I keep bumping into this
error:
Caused by: java.lang.IllegalArgumentException: Cannot convert
org.jfree.data.category.DefaultCategoryDataset@28dd6067 of type class
org.jfree.data.category.DefaultCategoryDataset to interface
org.jfree.data.general.Dataset
I can even manage to have the two class names be exactly the same (Dataset), so the error
message baffles a beginner like me.
I have tried stuff like (taken from an example):
<p:chart chart="#{myEntity.chart}">
</p:chart>
public JFreeChart getChart() {
return createChart(getDataset());
}
private JFreeChart createChart(Dataset dataset) {
JFreeChart chart = ChartFactory.createStackedBarChart(
"Public Opinion : Torture of Prisoners",
"Country", // domain axis label
"%", // range axis label
(CategoryDataset) dataset, // data
PlotOrientation.HORIZONTAL, // orientation
false, // include legend
true, // tooltips?
false // URLs?
);
return chart;
}
@BypassInterceptors
public Dataset getDataset() {
DefaultCategoryDataset dataset = new DefaultCategoryDataset();
dataset.addValue(81.0, "Against all torture", "Italy");
return dataset;
}
add time series charts

Project: Seam
Issue Type: Feature Request
Components: PDF
Reporter: Yan Langlois
Assignee: Norman Richards
Fix For: 2.1.2.CR1
It would be great to have the possibility to diplay only a couple of label on a chart
(x-axis). for example : display months instead of days (like in this chart :
