Brooklyn says hi. :) Let me say that even this simple demonstration of charts looks amazing - this really brings up a lot of possibilities. However, I think it's a bad idea to include this code directly in SMW. The Google Charts service is free, but it's not open source, which means that (a) they could start charging for it at any time, and (b) the whole project now becomes reliant on this URL staying up. Even if neither of those ever become a real issue, there may be companies and organizations that have a strict open-source policy for the applications they use, and SMW would now violate those. I think this code is much better off getting packaged as a "Semantic Google Charts" extension, using the same hooking-into-the-ask-query approach that Semantic Google Maps now takes. I don't know if I should be the one to do that (I guess we can talk about that). But if that happens, it still would be nice to have an open-source graphing library directly within SMW - that JpGraph library looks like a good one, although the graphs it creates look ugly as sin compared to Google's - maybe that can be changed. -Yaron On Tue, Jul 8, 2008 at 10:15 AM, Krabina Bernhard <kr...@kd...> wrote: > > > Now this may be the fastest granted wished feature ever :) > > wow!

Karlsruhe says Hi. :) Good point, Yaron. SMW sure should not be dependant on an external service -- that is why the Google Charts API visualization is switched off by default. But you are right -- it should actually be an extension of itself, and removed from the SMW code entirely again. As soon as I have the time -- or if someone takes it up -- it should be done. Regarding 3rd party libraries to replace Google's service: * JpGraph, unfortunately, is not Open Source * MovGP0 suggested to take a look at gnuplot, which is extremely powerful, stable, well maintained, etc. It is just a pity their demo plots also don't look too nice (maybe there are options for nicer fonts and anti-aliasing?). And it would be a binary extension -- gnuplot is written in C (which makes installations in some settings more complicated), but otherwise it seems workable. * ploticus seems to be an alternative as well. But it seems to be pretty similar to gnuplot, so I could not decide between the two (they both look similarly pretty...) Oh, and there was a mistake in the installation description. It should not be include_once('extensions/SemanticMediaWiki/includes/SMW_QP_GoogleChart.php'); but include_once('extensions/SemanticMediaWiki/includes/SMW_QueryProcessor.php'); It is updated on the wiki <http://semantic-mediawiki.org/wiki/Help:Googlebar_format> Yaron Koren wrote: > Brooklyn says hi. :) Let me say that even this simple demonstration of > charts looks amazing - this really brings up a lot of possibilities. > However, I think it's a bad idea to include this code directly in SMW. > The Google Charts service is free, but it's not open source, which means > that (a) they could start charging for it at any time, and (b) the whole > project now becomes reliant on this URL staying up.

Oh, I didn't realize JpGraph wasn't open-source - that's too bad, I guess. :) One other possibility is Javascript-based graphing, which I'm guessing is how Google Charts works anyway. I found this library, PlotKit, which is open-source and actually looks quite nice: http://www.liquidx.net/plotkit/ On Tue, Jul 8, 2008 at 11:22 AM, Denny Vrandečić <dv...@ai...> wrote: > Karlsruhe says Hi. :) > > Good point, Yaron.

Just joining in the "brainstorming" on graph packages. We use LimeSurvey (http://www.limesurvey.org <http://www.limesurvey.org/> ) for doing online surveys and it provides nice charts based on the jpGraph library. Denny mentioned it already and stated that it is not open source, but I think there is an OS version (see http://www.aditus.nu/jpgraph/jpdownload.php, it says "JpGraph is released under a dual license. QPL 1.0 (Qt Free Licensee) for non-commercial, open-source or educational use and JpGraph Professional License for commercial use.") Furthermore, to complete the list :-) : - GraPHPite: http://graphpite.sourceforge.net/ (which I think should come with the PHP PEAR package) - Open Flash Chart: http://teethgrinder.co.uk/open-flash-chart/ which is also PHP based and seems really nice, but does (as far as I know) rely on flash and on chart data which is actually _saved_ on a file somewhere.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, gnuplot supports anti-alias under certain circumstances. The better solution is to use the SVG-Export.
