I want to create time series chart usinf xml data source ...Following is the xml file /measCollecFile/measData/measInfo -- main data source xpath subDataSet :- /measInfo/measValue/r takes parameter(p) as user input Filter for subDataset:- value of p attribute in (<r p="">22</r> ) == user input Currently i am using subDataset for the time series chart shown in detail band. As aresult, i get 3 charts for each record. And if a put it in summary band i get only one chart with value plotted only for the last record.... How can i use this value of r element (22 in above example) in time series chart as value??? or Otherwise tell me the other way of creating the chart or time series chart with value of r element being plotted on the y-axis and endTime in (<granPeriod duration="PT5S" endTime="2013-06-14T02:15:04.160+05:30"/>) being plotted on x-axis.. <measCollecFile> <fileHeader fileFormatVersion="32"> <measCollec beginTime="2013-06-14T02:15:00.000+05:30"/> </fileHeader> <measData> <managedElement/> <measInfo> <job jobId="Server1"/> <granPeriod duration="PT5S" endTime="2013-06-14T02:15:04.160+05:30"/> <repPeriod duration="PT5S"/> <measType p="1">CPU_UTIL_SYSTEM</measType> <measType p="2">CPU_UTIL_USER</measType> <measType p="3">IDLE_PROCESSOR_THREADS</measType> <measValue measObjLdn=""> <r p="1">10.18</r> <r p="2">3.19</r> <r p="3">0.0</r> </measValue> </measInfo> <measInfo> <job jobId="Server1"/> <granPeriod duration="PT5S" endTime="2014-06-14T02:15:09.162+05:30"/> <repPeriod duration="PT5S"/> <measType p="1">CPU_UTIL_SYSTEM</measType> <measType p="2">CPU_UTIL_USER</measType> <measType p="3">IDLE_PROCESSOR_THREADS</measType> <measValue measObjLdn=""> <r p="1">6.49</r> <r p="2">5.49</r> <r p="3">0.0</r> </measValue> </measInfo> <measInfo> <job jobId="Server1"/> <granPeriod duration="PT5S" endTime="2013-06-14T02:18:14.162+05:30"/> <repPeriod duration="PT5S"/> <measType p="1">CPU_UTIL_SYSTEM</measType> <measType p="2">CPU_UTIL_USER</measType> <measType p="3">IDLE_PROCESSOR_THREADS</measType> <measValue measObjLdn=""> <r p="1">2.79</r> <r p="2">2.39</r> <r p="3">0.0</r> </measValue> </measInfo> </measData> <fileFooter> <measCollec endTime="2013-06-14T02:20:00.000+05:30"/> </fileFooter> </measCollecFile>
