Generate time seriies graph from multiple lists

[dheeraj.madhu]

Hi. I am trying to generate the time series graph using List data source.

My JRXML for graph is 

<group name="timeSeries">                                                                                                                <groupExpression><![CDATA[null]]></groupExpression>                                                                                       <groupHeader>                                                                                                                             <band height="250">    <!-- Time series chart -->                                                                                         <timeSeriesChart>                                                                                                                         <chart evaluationTime="Report">                                                                                                           <reportElement positionType="Float" x="0" y="25" width="550" height="175"/>                                                           <chartTitle/>                                                                                                                         <chartSubtitle/>                                                                                                                      <chartLegend/>                                                                                                                    </chart>                                                                                                                              <timeSeriesDataset timePeriod="Minute">                                                                                                   <dataset incrementType="None"/>                                                                                                       <timeSeries>                                                                                                                              <seriesExpression><![CDATA["Count"]]></seriesExpression>                                                                              <timePeriodExpression><![CDATA[new Date(Long.valueOf($F{timeStamp})*1000)]]></timePeriodExpression>                                   <valueExpression><![CDATA[integer.valueOf($F{count})]]></valueExpression>                                                         </timeSeries>                                                                                                                         </timeSeriesDataset>                                                                                                                  <timeSeriesPlot isShowLines="true" isShowShapes="false">                                                                                  <plot/>                                                                                                                               <timeAxisFormat>                                                                                                                          <axisFormat>                                                                                                                              <labelFont/>                                                                                                                          <tickLabelFont/>                                                                                                                  </axisFormat>                                                                                                                     </timeAxisFormat>                                                                                                                     <valueAxisFormat>                                                                                                                         <axisFormat>                                                                                                                              <labelFont/>                                                                                                                          <tickLabelFont/>                                                                                                                  </axisFormat>                                                                                                                     </valueAxisFormat>                                                                                                               </timeSeriesPlot>                                                                                                                </timeSeriesChart>     <!-- Time series chart -->                                                                                 </band>  <!-- <band/> -->                                                                                                         </groupHeader>                                                                                                                    </group>[/code]

 

And My List is 

 

 

public class EventBean {    private String name;    private List<TimeSeriesBean> timeStamps;}public class TimeSeriesBean {    private String count;    private String timeStamp;}[/code]

Data passes to Jasper is List<EventBean>. Each EventBean is having time stamp and count at that time stamp.

If i have only one Element in List<EventBean> I get one time line graph. If 2 or more elements it then i can't print the graph.

I want to append all data to same tiem series chart. How to achieve this?

PS:Sorry Can't format this XML. While editing the post it shows it is already formated.
