Hello, Could you explain how to make a gantt chart using iReport ? Let's say that on java site I have list of Task objects which I pass to jasper-report mechanism (I want to generate a html report). Each Task contains fields like: -Date startDate -Date endDate -String name -String description -Long realizedPercent -List<Task> subTasks Now I have to create a proper .jrxml file describing the report structure using iReport. Firstly I create fields that reflect fields in the Task class. Then I select gantt chart from palette, right-click on the chart and select "chart data" and here comes the problem. What should I select on "dataset" tab (attached screen) ? How should I fill "Time period series" (attached screen)? Please, help me.
