How do I create a line graph of information (just like the stock price charts in Yahoo quotes)? Is CGI with Perl the way to go or Java or Javascript?  Yahoo seems to use a CGI script of somesort and it is really fast.  How can I do this? Thanks

You have 3 options:

1) Use JAVA
2) Use Dynamic HTML
3) Write your own CGI.

I suggest follow the 3rd option.

There are plenty of ways you can accomplish that.  You can use GNU Plot (Which I haven't used much because it's very rigid) or you can use the GD Library written by Thomas Boutell.

The gd library is very good and easy to use.  I have coded quite a few cgi scripts that graph data and it works very well indeed.  The gd library is written in C, and as I said before, its pretty easy to use and very reliable.

If you need some code examples please send me an email to

and I'll be glad to help
