Hello all .
I'm still kind of new to Ruby and trying to graph data in real-time but I
can't seem to find a suitable graphing engine. I've sniffed around using my
friend Google, but I didn't find anything concrete. Has anyone out there
done a GUI graph that updates in real-time (something simple like a line
chart)? Here's some pseudocode to help get my point across:
graph = SomeGraphEngine.new
graph.type = "line"
xvalues = Array.new
yvalyes = Array.new
for num in ( 0 .. 36 )
xvalues << Float( num * 10.0 + 50 )
yvalues << Float( Math.sin( num * Math.pi / 15.0 ) * 16.0 )
graph.coords( xvalues, yvalues )
graph.draw
end

what os? gnuplot can easily do this...

Hello all .
Hi,
I think GraphViz is what you're looking for 
the tool: http://www.graphviz.org/
the ruby module: http://raa.ruby-lang.org/project/ruby-graphviz/
<disclaimer>
never used the ruby module yet, as I am pretty new to Ruby (< 30 days).
</disclaimer>
I have used GraphViz however, and is a really cool piece of software 
check out the gallery: https://graphviz.org/gallery/
Good luck,
Alex
Oh, sorry ... forgot to mention the OS is Windows XP Pro. I went to
Sourceforge to grab Gnuplot but there weren't any files listed other than
the manual:
Do you have a link to the full code w/ examples?

I had tried GraphViz in the past and couldn't get it to work. I installed
the Windows binary from GraphViz's site then installed the Ruby module.
Running the samples output (what appears to be) byte data which I redirect
to a file with the extension 'png'. When I try to view the output, nothing
renders it. Excluding that, I was hoping to find something more in-line
with http://zedgraph.org/wiki/index.php?title=Main_Page (only for Ruby
instead of C#).
