Gantt Charts

[rkm258]

Hi,

   I tried generating gantt charts using iReport 3.1.2. I'am able to display the activities and their time range.

   The problem is "identifying task & subtask". How should the result set records be arranged to obtain these values.

  For ex: below columns are

task , subtask, task_startdate, task_enddate,subtask_startdate,subtask_enddate

  step 1,activity 1";"2009-03-13";"2009-04-01";"2009-03-13";"2009-03-16"
step 1,activity 2";"2009-03-13";"2009-04-01";"2009-03-17";"2009-03-19"
step 1,act under act 1 of step 1";"2009-03-13";"2009-04-01";"2009-03-13";"2009-03-14"
step 1,act desc";"2009-03-13";"2009-04-01";"2009-03-18";"2009-03-20"
step 1,ew";"2009-03-13";"2009-04-01";"2009-03-22";"2009-03-28"
step 2,act of step 2";"2009-03-31";"2009-04-09";"2009-03-31";"2009-04-02"
