: I am developing a web based front end for Oracle. The application basically takes takes HTML input
: and querries the databse based on the conditions requested by the user. The db then returns a time
: series result which needs to be graphed before being displayed back to the web (in HTML).
There is gd library. Recent versions output png, which is understood by
modern browsers. It have nice Perl interface, so combining it with
DBD::Oracle you can plot graphs directly from database.
There is also highlevel interface module on top of it called GIFgraph.
Search on CPAN.
The only "intuitive" interface is the *. After that, it's all learned.
