[erlang-questions] Graphing options in erlang

Another option is perhaps to use eplot which is written in pure erlang. 
Eplot is not complete, but it works well for alot of cases. It uses egd 
as backend and can output png, eps or raw bitmap. It uses wxErlang to 
view results if no output option is given. I use it to visualize data 
when benchmarking. It suits my needs but I haven't spent a lot of time 
to add new features or fine tuning it.

 From command line it uses escript but one can use the module egd_chart 
to incorporate it in any other module. Documentation is sparse at the 
moment.

Interested parties should direct their attention to:
