I am interested in creating a cgi perl script that I can publish on the web=
that will tie into a mysql database and create a x,y axis graph based on d=
ata selection. Any suggestions are greatly appreciated.

Thank you,
Chris Stinemetz

Cool.

I shouldn't, but take a look at
http://suryahunter.com/wiki/hunter/Charts/Weather/Temperatur e_Forecast for
an example of creating a chart using Perl. DBI or DBIx::Class should make do
for the database layer. You'll probably not want to use a cgi script, as
that is so twelve years ago.

I'm not in front of a computer right now. However, IIRC there are Math:: and
Graph:: modules. I'd also look at the ImageMagick modules if you need a
picture from that point. Maybe search cpan for 'plot' as well.

You could probably figure out how to do plots in straight css, but idk. And
it wouldn't be the easiest to do.

One method is to use gnuplot. Write out your x,y data to a file, fork
gnuplot, and send it commands to plot the data and save as a PNG
file. Then, return an HTML page that displays the PNG file as an
image.

There are CPAN modules to help you control gnuplot. However, it is
easy enough to send it commands using a pipe (see perldoc -f open).
It is even easier to write out the gnuplot commands to another file
and tell it to execute those commands.

I use GD::Graph with cgi to create graphs on the fly.

There are some examples on http://gdgraph.com/
