I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I''ve used GDChart in the distant past but I can''t find info about it and ruby. The specific feature that I need is the ability to control the color of each datapoint pip. I''m making statistical process control charts (XBAR/R) and out of control points should be highlighted in another color or shape. Thanks! Gary
Have you had a look at Geoffrey Grosenbach''s Gruff Graphs? http://nubyonrails.com/pages/gruff -- Posted via http://www.ruby-forum.com/.
Not sure about GD2, but if you can use ImageMagick/RMagick then the gruff gem is really cool.

For some discussion of possible Gruff installation pitfalls, see: http://tomcopeland.blogs.com/juniordeveloper/2006/02/charts_and_grap.html Yours, tom
I hate Gruff. For very very simple stuff it''s ok, but for anything remotely complex i.e. Most statisitcs graphs, its crap Maybe its because i''m fustrated with the lack of decent graphing tools for Ruby. Yeah, i know there are others, but they are a nightmare to use. What i''d do for JFreeChart for ruby..... -- Posted via http://www.ruby-forum.com/.
