RE: graphics in perl
I'd recommend interfacing with R (http://www.r-project.org) From: Malka Cymbalista [mailto:[EMAIL PROTECTED] Sent: Sun 22/06/2008 10:27 AM To: [EMAIL PROTECTED]; beginners@perl.org; [EMAIL PROTECTED] Subject: graphics in perl We are running perl 5.8.5 on a Linux machine that is running apache 2.2.6 with mod_perl 2.0.3. Our data is in a MySQL database (MySQL 5.0.45) We have been asked to write a web application that requires plotting capabilities. We do most of our web programming in perl so I am looking for a perl module that has the following features: 1. ability to create histograms 2. ability to create x,y plots 3. ability to zoom in on a portion of the graph 4. ability to calculate the distance between 2 points on the graph 5. ability to hover on a point and bring up some text Does anyone have any suggestions for which perl modules we should look into?

CGI scripts, security and MySQL
Hi I need to know what is the accepted way of handling the following. I have a MySQL database, and a host of CGI scripts which present forms to the users as web pages, they fill them in and then the data is written to the database. I need to make this secure such that only users I want can use the system. I want to set up a username and password so that users can log in once at the beginning of a session, carry out their work filling in various forms and writing to the database, and then log-out at the end. What is the best way to do this? I've thought about creating a MySQL user/password for each person who needs to enter data, but I don't want them to have to enter their username and password on every form. I guess what I need is some sort of persistant DBI connection that is present over multiple runs of various CGI scripts (until the person logs off or the browser is closed...) I am running Suse Linux 8.2, MySQL 4, Apache 1.3.28 and perl 5.8.0 Cheers Mick -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
