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:
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:
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#).
