Re: [udig-devel] BIRT Charts and Integration ideas
|
Hi, excuse my late reply.
As Adrian states, we from JGrass made a first approach some time ago
using the birth charting mechanism for the plotting of data. It is
different from what you did for the report.
We were not so happy with it, since te perfomance is very low in the
case of charts with loads of data, which are very common in scientific
environments, so I think we will discard that one.
JFreechart has now a native SWT support and the demos look perfect as
they were in the swing environment, so I'm pretty sure, we will step
back to that one. I will just need to test some cases for stability.
Obviously, as any other on this list, I'm looking forward to see the
birt integrated reporting plugin, that will be a great enhancement!
Good Eurobios guys, my compliments!

Nice; how is your experience with BIRT charts going? I have been
thinking of making an abstract ReportOp that has the task of
creating an html report and opening up in the web browser editor.
Are you thinking of using the BIRT chart controls live in a view?
Or even more cool would be live on the Map using a MapGraphic... I
should also point out that with Jesse's new ApplicationGIS utility
method you should actually be able to integrate map and selection
output into a normal BIRT report.
FYI: We've written a customer BIRT report element which provides a
"Map" in the BIRT report designer. This can be dragged onto a
report, sized appropriately, etc. When the report is rendered (pdf,
html, etc) a Map is drawn. Extension point mechanisms are then used
to allow other code to filter/bound what is drawn in the reported map.
This all works fairly well. Eurobios would be more than happy to
make this code available as a community plugin.
[This is nothing to do with BIRT charts, though, just BIRT reporting
in general]
cheers,
Vince.
Note: BIRT's report element extension mechanisms/Java API are
unfortunately very poorly documented and fairly poorly designed, at
least in terms of the vast amount of boilerplate code one must
provide to enable such basic things as having the user able to
resize the map in the report.
