Re: [FINS] is this still alive? JFreeChart option?
Robin
I am also interested in applying it... but my issues are not so
much compatibility but more the points that Jorg raised i.e.
does it expose all of the functionality of JFreeChart - I get
the impression from looking at the docs and the schema that
it only offers a limited subset of the full power of JFreeChart.
So, then, the issues are:
* will Fins (soon? ever?) be upgraded to cover all JFreeChart?
* is it not better to try and find some way to work with
JFreeChart directly (and how easy would this be?
Anyone else with experience in charting that can address this?
Thanks
Derek
PS For what its worth, I have a stylesheet that can build
relatively simple bar, line and pie charts from a "standard"
XML source file (somewhat similar to FINS)... if anyone is
interested.

Jorg,
I used Fins extensively on a project last year (Cocoon 2.1.5), and it
worked great for me.
I've just updated this project to use Cocoon 2.1.7-dev and it works
fine. Minor changes were needed to the Fins build.xml to get it to
build with cocoon - I don't have the details here, but if you need any
more info let me know.

Thanks for confirming my main concern.
@Luca: can you comment on this? Is there an easy way to expose all of
JFreeChart in Fins or does Fins need adjusting for every feature
JFreeChart provides? (i have not looked at the sources yet sorry)

Hi Antonio
Are you aware of xReporter http://cocoondev.org/xreporter/index.html?
Out of the box this is likely to handle your report linking requirements and
will output reports in HTML, PDF, Excel, or CSV formats.
>From memory there has been some discussion of FINS integration on the xReporter
mailing list, you might want to take a look at the archives.
Cheers

Hello Antonio!
Some time ago, I looked at expanding the Fins wrapper. This is not that
difficult, as you only need to add some logic in the main renderer selector
method within Fins, along with defining your own markup for the data sets.
Merely using new chart types, using the same base-data markup, would be
quite easy.
Other than that, I'm using Fins for a data warehouse application and it's
working great, apart from the Fins serializer being quite CPU-intensive. I
don't how to optimize the serialization, any ideas here?
Best regards,
Ulf Sahlin

Hi,
What about a set of commons-digester rules?
I am in vaporware stage on a project which will need a reporting
system, but not the typical simple reporting like "here's a table,
format it nicely", but some powerful reporting with several data
detail levels, linked back and forth, with graphs of many different
types (including some not yet supported by jfreechart).
So I am thinking of:
- Extending jfreechart to support one or more additional graph types
(e.g. gauge)
- Using it directly (or extending a reporting product that integrates
it, if possible) so that I can create reports (at least HTML and PDF
output formats needed)
Any hints on that?

Yes, your impression is correct.

We're currently discussing it on the list. It will require substantial
effort, but the fine guys at Outerthought may give us a hand, in view of
Fins integration into xReporter.

Well, JFreeChart is still in pre-release, and, while powerful, is
complex and has a penchant for refactoring for refactoring's sake:
changed package names, changed class names, etc.
Needless to say, this attitude has slowed us quite a bit... hopefully
JFreeChart will settle down after 1.0 release.
To sum it up: I don't think going directly to JFreeChart would save you
a great deal of time.

I also thought about a charting software built using XSL and SVG... but
the sheer complexity of doing something more complex than pie and bars
scared me away :(
Yes Jorg, Fins needs manual adjusting to every new feature of
JFreeChart, there is no "automagic" way to wrap an XML layer around it,
AFAIK.
