[clug] Postscript Graphing Library for programming

Hi people,

I thought I'd put out a request to the Lazyweb for information about 
drawing graphs (bar charts, line charts, etc) in a program (e.g. in 
Perl) that can be output directly to a printer.  I'm trying to graph 
information that has a lot more statistical resolution than the 65,536 
data rows that OpenOffice Calc seems to be limited to.  My current 
program uses the GD::Graph library, which is fine if you want to output 
a PNG at a large resolution, load it into GIMP, scale it to the page and 
print it - because that's the only way I've found so far of actually 
outputting the graph in anything near the printer's actual resolution 
(everything else seems to think that 50DPI is fine).  I don't mind if I 
do the rasterisation inside the program rather than inside the printer 
driver - so I don't _have_ to output PostScript - but I want something 
that can take up an entire sheet of A4 at 360DPI or better.

Any recommendations?

Have fun,


P.S. I've tried ploticus.  I intend to translate its entire manual into 
Esperanto - that way more people would be able to understand it than the 
way it's currently written.
