I want to create graphs based on values from database.
Can any one suggest good tutorial for this with good codes or some sample code so that
I can work because I am new to GD Library and PHP.

Any help is highly appreciable.

Thanks

The absolute best solution I've found is jpGraph

http://www.aditus.nu/jpgraph/

There are many example files in the download package.

I would definately second that. Jpgraph is absolutely the best.

I downloaded JPGraph. When I run it 's giving error

JpGraph Error: No path specified for CACHE_DIR. Please specify a path for that DEFINE in jpgraph.php

Here what path I have to give?

Thanks

It's been awhile since I installed jpGraph, but the path you enter should be your web server path -- something like

/home/user/www/...

this varies from server to server. A good way to find this out, among other things is to make a .php file and in it type this

<?
phpinfo();
?>

save that file to your server's root and go to it in a web browser.

When you do, you should see a section called Apache Environment, under that should be an entry called DOCUMENT_ROOT

add to this your web path to to jpgraph cache directory and you're good to go

Sorry for asking as I am new to this.

I did enter all the details, it's not working. Can you please clarify where exactly
I have to enter the path.Below is the section

if (!defined('CACHE_DIR')) {
if ( strstr( PHP_OS, 'WIN') ) {
if( empty($_SERVER['TEMP']) ) {
die('JpGraph Error: No path specified for CACHE_DIR. Please specify a path for that DEFINE in jpgraph.php');
}
else {
DEFINE('c:/program files/apache group/apache/htdocs', $_SERVER['TEMP'] . '/');
}
} else {
DEFINE('CACHE_DIR','/tmp/jpgraph_cache/');
}
}

Any help is highly appreciable and thanks

Whatever changes you made, undo them

I just looked at my jpgraph.php and I see a section like this:

// Directories for cache and font directory.
// Leave them undefined to use default values.
//
// Default values used if these defines are left commented out are:
//
// UNIX:
// CACHE_DIR = /tmp/jpgraph_cache/
DEFINE('TTF_DIR','/home/image1/www/jpgraph/fonts/');

//
// WINDOWS:
// CACHE_DIR = $SERVER_TEMP/jpgraph_cache/
// TTF_DIR = $SERVER_SYSTEMROOT/fonts/
//
//

try un-commenting the CACHE_DIR = $SERVER_TEMP/jpgraph_cache/ line

if that doesn't work, create this directory C:\tmp\

[jacobe]

Uncommented that line under windows.

Now I am getting errors

Warning: Unknown(jpgraph_plotmark.inc): failed to open stream: No such file or directory in Unknown on line 0

Fatal error: (null)(): Failed opening required 'jpgraph_plotmark.inc' (include_path='.;C:\php4\includes\pear') in Unknown on line 0


Any advice?

By the looks of it i am having the same problem as you described. Did you manage to solve this and get Jpgraph working? If so could you let me know how as i have been banging my head against this problem for days and its starting to hurt!
