I want to create some graphs programatically, using Java or Perl. I want to replicate a graph like the following on 'grid paper':
The only thing missing from the example is the grid background (sorry, i am not that talented to show that here). For Java, i found the library jfreecharts, but I didnt dig too deep into it. For perl, i found GD::Charts. Nice module, but I couldnt figure out how to create the grids properly...
I am looking for code examples, not pointers to doc (of course I would like pointers if you also give me code samples).
