Used trinidad chart tag <tr:chart> in XHTML, but no output is coming
Below is the code where i am facing the issue, i am not getting the output of the graphs. Kindly help me.
My XHTML code
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:tr="http://myfaces.apache.org/trinidad">
<h:body>
<h1>Director Screen</h1>
<tr:document>
<tr:form>
<tr:chart value="#{chartBean}" type="pie" />
<tr:chart value="#{chartBean}" type="bar" />
<tr:chart value="#{chartBean}" type="circularGauge">
</tr:form>
</tr:document>
</h:body>
</html>
Java Code
package com;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import org.apache.myfaces.trinidad.model.ChartModel;
@ManagedBean(name = "chartBean")
@SessionScoped
public class ChartBean extends ChartModel {
@Override
public List<String> getGroupLabels() {
List&开发者_运维知识库lt;String> groupLabels = new ArrayList<String>();
groupLabels.add("Java");
groupLabels.add("Linux");
groupLabels.add(".NET");
return groupLabels;
}
@Override
public List<String> getSeriesLabels() {
List<String> seriesLabels = new ArrayList<String>();
seriesLabels.add("Love it");
seriesLabels.add("Hate it");
return seriesLabels;
}
@Override
public List<List<Double>> getYValues() {
List<List<Double>> chartValues = new ArrayList<List<Double>>();
// Fill the groups
for (int i = 0; i < getGroupLabels().size(); i++) {
List<Double> numbers = new ArrayList<Double>();
// fill the series per group
for (int j = 0; j < getSeriesLabels().size(); j++) {
numbers.add(100* Math.random());
}
chartValues.add(numbers);
}
return chartValues;
}
}
It's mandatory to have a <h:head> in the template right before <h:body>. That's where all the JSF 2.x scripts and stylesheets end in. I won't be surprised if the <tr:chart> has some JS/CSS dependencies.
I was unable to get the graph in xhtml file, so i copied the same in jsp and got the graph.
I had a similar problem and solved it by adding the following lines to web.xml:
<mime-mapping>
<extension>svg</extension>
<mime-type>image/svg+xml</mime-type>
</mime-mapping>
