Hi,
I would like to show more than just one time frame per Y-Axis series of my gantt chart.
For example, on the Y-Axis are hotel rooms and on the X-Axis are the time frames that indicate that the room is blocked.
Sadly BIRT has this bug when it comes to showing multiple time frames in one series with grouping on the Y-axis ( bugs.eclipse.org/bugs/show_bug.cgi?id=376935 ).
So it thought that adding a dynamic number of Y-series depending on the number of time frames could be a workaround.
Now there are two problems for me:
First, my data set looks like this:
Room | start | end
room1 | 12412341| 12541234
room2 | 12342432| 13341234
room1 | 22345234| 23341234
...
So I think I have to refactor the data set that I looks like this, right?
Room | start1 | end1 | start2 | end2
room1 | 12412341| 12541234 | 22345234| 23341234
room2 | 12342432| 13341234 | 0 | 0
This structure would not be possible with SQL as I do not know how many columns I need, but I would have to refactor the data set using Javascript if I am not mistaken.
After that, I would need to add a dynamic number of Y-series to my gantt chart.
Is there some example how to do that for the newer BIRT versions? I only found jasonweathersby.sys-con.com/node/1200405/mobile and could not really get it to work in BIRT 4.2.1
I would be thankful for some input whether my thoughts are correct and maybe an example how I could add a series to a gantt chart?
Thanks in advance, regards,
Hauke
