RE: [PHP-DB] Use php to plot graph.
yes, it is possible - read up on the .PNG image format, as it is possible to create graphs ind images dynamically to suit the data and figures youve extracted from the database -Original Message- From: Denny Ow [mailto:[EMAIL PROTECTED]] Sent: 03 December 2001 16:14 To: [EMAIL PROTECTED] Subject: [PHP-DB] Use php to plot graph.

RE: [PHP-DB] Use php to plot graph.
I'm working on a project right now where we call PHP from within an HTML page, send it vars using a POST method, and then use that to draw a graph. We're drawing bar graphs now but one of my coworkers did a line graph. You call the PHP as an img src tag and have PHP return a .png. We used the SAMS Teach Yourself PHP4 in 24 Hours book - it's Hour 14 where you do all sorts of stuff with images. It's not easy - you draw each line based on the endpoints and you can fill rectangles and stuff, but the end result can be pretty impressive. I'd send you my graph but it's on a development website that's password protected. If you're really interested I could save the image and download it to you. -Natalie -Original Message- From: Denny Ow [SMTP:[EMAIL PROTECTED]] Sent: Monday, December 03, 2001 11:14 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] Use php to plot graph.

Re: [PHP-DB] Use php to plot graph.
There are a few ways to go about this: You could: 1) Use little image blocks to dynamically build bar graphs. It's not too hard with PHP. Make some little square (or round or whatever) gifs (with transparent edges), and then position them on a background JPEG or gif using DIV tags. Make an object in PHP and feed your query results into it? 2) Use the gd library and graphics commands added in PHP 4 (you're gonna want to read up on this one...) to create images dynamically. This is much more server-intensive than option #1. and takes more programming, but can be really slick. Then you can draw all sorts of graphs - not just bar graphs or scatterplots. Wheee. 3) Combining Java and PHP and MySQL to draw images is also totally possible. I avoided this approach because it's all client-side. There is also an example of this in the JDK from Sun, and it works pretty well, but is a little buggy. Maybe it was my code, maybe it's Java, but it seemed incomplatible across platforms. Make an object in PHP that creates the necessary JavaScript, and feed your query results into it. 4) Program some really slick ascii graphs. No joke, I did this a while ago. Nice output. Really fast. You can do line graphs, too. Cheers, db Denny Ow wrote: Hi, Jus wanna to ask if it is possible to use php to plot graph using data retrieve from mysql. If yes, how should i go about?

Check out the graphics section of http://www.phpclasses.upperdesign.com/. It's got some neat classes for creating graphs. regards -- Jason Wong - Gremlins Associates - www.gremlins.com.hk /* Under deadline pressure for the next week. If you want something, it can wait.
