Currently working on the Geocat branch of the GN project, we integrate some administration part to log search queries made through the GUI.
Among the functionnalities, we have to display charts (pie, bar) to present some stats (eg: number of searches by year, month, etc).
Some of these functions could be integrated into the trunk.
We already looked at JFreeChart (http://www.jfree.org/jfreechart/) for an other project and it seems to produce nice graphics.
It is opensource though the Dev manual is not free.
What do you think about using this for the graphics. Do you have any experience, maybe with another package ?
Thanks

Hi,
we decided to use JFreeChart to generate graphics.
Hi Nicolas,
I had a look but didn't feel I had much to contribute to the discussion since I don't know other packages, hence my silence However, it looks like a very good solution, so I fully support your choice. Looking forward to the result!
Ciao,
Jeroen

Couldn't contribute anything on JFreeChart but can I ask a slightly more oblique question? Which query are you using to the do the logging/stats generation? Is it the generated lucene query (ie. after going through the query xslt etc)? Reason is that we're planning some changes that expose the lucene query string to the user and which will (not yet but soon) allow users to build and save these query strings from/to a client side store (with most of the query parsing and validation in the client as well). A prototype is in the BlueNet sandbox (see the 'Lucene Search' tab). Really would like to use your query logger/stats analyzer so I'm interested in what you're using to generate the stats. Maybe others are working on/have done something similar to this too?
Cheers,
Simon

We're using JFreeChart as well, it's easy to use and generates high quality
images. It would be nice to see some stats gathering functionality added to
GN. Right now, we're interested in basic usage counts, and are logging the
URL and query string of all requests to /geonetwork/srv/.

Hi Simon,
I realized this afternoon that I forgot to answer your message and
would like to apologize about that.
Yes, indeed, we are logging after the Lucene work, juste before
returning from the search result. When the Lucene expression is buit,
the Logger class inserts into the database (in Requests and Params
tables) information about the current search query (user ip, searched
terms, number of hits, simple vs advanced search, etc.)
Then, when playing with statistics page, queries are made to the
database to extract logged information and to present it: tagcloud for
most searched queries, tabular information, charts.
If at all possible, I would suggest staying away from an in-browser Java
requirement. Are there any suitable JavaScript (or even server side)
alternatives?

Hi Tom
There is no in-browser Java for the statistics part. Java is used on
the server side to generate the image, and its url is sent to the
client for dislplay.
However, it looks like a very good solution, so I fully support your choice. Looking forward to the result!
