SVG Canvas

Steven Quinones-Colon

12/13/2006 5:34:00 PM

I've been looking for a couple of days now and I can't find a library
for svg graphics with a canvas object so I can make a financial
charting application(stand alone, not web based), is there such a
thing? maybe I'm missing something obvious.
Best regards,
Steven

Most of the available GUI libraries support graphics. I have been using the
Qt library for this sort of thing, and the graphics are quite acceptable:

http://localhost/ruby/graphinity/index.html

http://localhost/ruby/gravity/index.html

I have only used the Qt library, there are several others, most of them
offer this sort of graphic library. It's not necessary to create a GUI in
order to use the graphic libraries they offer.

If you were planning to create a GUI to go along with your graphic images,
then this approach makes even more sense.

Thank you -- I managed to overlook the URL content as I collected the data
locally.

I haven't tried it at all, but there are Ruby bindings for the Cairo
library (http://cairographics....) which should produce really
nice output.
