Anyone been successful in adding a gantt to a report in Jaspersoft Studio? I can't find any instructions except on the Fusion Website and their instructions are around how to add the code. I can't seem to get this to work. I always receive errors "Error compiling report design".
You need to create a graph of Gantt type. The data source should be a query which can be used to link to the head report.
Then you need to map the id of the investment (from the main report), to the id in the Gantt query.
Did you succeed in getting a Gantt working properly ? I've the same problem and I'm looking for some advice.
IMO, the Gantt is not usable as it is based on Flash, a technology you normally cannot use in professional environments.
If you do want to use the Gantt chart, you have to fiddle around yourself as there is no documentation on how the wizard in the JS Studio can be used to get the data to FusionCharts so the Gantt is painted as required.
Sorry to say, but this would really be a great feature if it worked...
