Jasperreports - Task Grouping in a Gantt chart

[Tiago Abreu]

I'm trying to create a widged-pro gantt chart that lists project durations by month. So far this is working fine, but now i have to add tasks to the "parent" project, that lists its phases durations (CER, SPP).

My Data table (SQL) is as follows:

Basically i want to create some kind of grouping so each phase is right bellow the main project duration bar, all in one project row.

My process is ID=$F{RANK} and Label = $F{NAME}

So far I'm not understanding the logic of the grouping, and I'm not finding any example of this being used. At the moment all records/projects show separate (repeated process), even the ones that belong to the same parent project.

And when i put the grouping expression like: $F{ID}.equals($F{Parent_prj), no change occurs.

This is what i'm trying to make (see image), as featured in the ireport designer manual:

Does anyone accomplished a similar design? or can point me in the right direction, or some kind of example, would be greatly appreciated.

Thank you for your time!

we don't use  "widged-pro gantt chart" since you cannot export report to PDF format or others.

We usually create "manual gantt" charts (using tables, cells, coloring cells,...)

 

I'd suggest to build something manually. You can easily group in your query and make gantt char manual as you need.

Hello Aurora,

 

You can't export the report containing widget pro charts from PPM in the Advanced reporting section? Is this not supported or its a bug?

 

Thank you.

Hello,

 

I'm not having problems running a report that features a widget pro gantt chart. It all works as expected, But you need to have flash installed and connfigure the properties file of you jaspersoft and uncomment the line that indicates the rendering for flash.

Thnak you.

Hi

 

Thanks for the tip. However, it will not be possible for OnDemand environments.
