Graphing libraries to create grid like charts
Hi,
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).
Thanks

maybe something along the lines of: http://stockcharts.com/help/doku.php?id=support:understanding_pnf_charts
They have a similar type chart near the bottom

I don't think either the GD::Charts or eh jfreecharts will do that. If you saw they could, I might have missed something.
If your output is going to a webpage, you might just want to use an HTML table - which is what the stockcharts.com site is using.
Otherwise, I don't know of a module that creates tables like those. I think you could just use the GD module to draw them though.

how hard would it be to use GD directly? Do you have experience? Perhaps a small example to get me going? Thanks Adam
May be this can be done by the development library that comes with OpenOffice.
I have no experience with it.

Would it be possible for you to provide a graphical version of what you want. EE now allows you to attach images. This would make it easier.
