Hello Olaf! Thank you for your answer! 2010/2/22 Dr. Olaf Hoffmann <Dr.O.Hoffmann@gmx.de> > Hello, > > I'm already working on a proposal for a related and more > general approach to present numerical data with SVG, > including some transformation mechanisms to apply > mathematical operations to data sets. > This is a very good news. I'm definitely going to go over your proposal and I think I will send you my ideas If I had any (but not to this mailing list). > For the 'science and technical community' we can assume, > that such a module would be very helpful and could result > in a dramatical increase of use of SVG in such areas > with some requirements to exchange data, present > and archive them in a simple enough and accessible > format. > Yes, I agree with you. I think it would be useful mainly for educational purposes.

Maybe the work mechanism of some common open source plotters should be studied. There is for example gnuplot and Inkscape, I guess both of them is able to save SVG output. > Proposal for a data presentation modul: > http://purl.oclc.org/net/hoffmann/rdml/ > > Proposal for path data in polar coordinates: > http://hoffmann.bplaced.net/svgueb/ppolar.xhtml > Thank you for your work, I truly believe that your polarPath element will get into the SVG specification in the near future.Received on Friday, 26 February 2010 15:06:21 UTC
