Run testsuit.php to get a list of all files and you can easily click on a file to see the code and the resulting image. /docs/index.html Documentation portal Requirements: ------------- Miminum: * PHP 4.3 or higher (earlier versions might work but is not actively tested) * GD 1.8.x or GD 2.15 or higher Recommended: * PHP 4.3.7 * Builtin GD library in PHP 4.3.x Installation ------------ 0. Make sure your PHP is 4.3 (preferable 4.3.7) and that you have compiled support for GD library. You must make absolutely sure that you have GD working. Please run phpinfo() to check if GD library is supported in your installation. If you don't have the GD library please consult the PHP manual under section "Image" for instructions on where to find this library. 1. Unzip and copy the files to a directory of your choice. For a global installation you should copy the files to somewhere in the PHP search path. 2. Check that the default directory paths in jpg-config.inc for cache directory and TTF directory suits your installation. Note1: The default directories are different depending on if the library is running on Windows or UNIX. Note2: Apache/PHP must have write permission to your cache directory if you enable the cache feature. By default the cache is disabled. 3. Check that all rest of the DEFINE in jpg-config.inc is setup to your preference. The default should be fine for most users. (See also Note 3. below) 4. Make sure PHP have write privileges to your cache directory if you plan on using the cache feature. 5. Read (really!) the FAQ on http://www.aditus.nu/jpgraph/jpg_faq.php. Troubleshooting --------------- 1. If you don't get any background images (but rather a solid black box) you are using GD 2.x but have forgotten to enable truecolor support. Correct this by enabling the USE_TRUECOLOR define. 2. If background images does not work make sure the settings of USE_GD2_LIBRARY corresponds to your installation, i.e. If you don't have GD2 then this define must be false! 3. If you are running IIS and Win2k and get the error "Can't find font' when trying to use TTF fonts then try to change you paths to UNIX style, i.e. "/usr/local/fonts/ttf/". Remember that the path is absolute and not relative to the htdocs catalogue. Some versions of GD for Windows also need you to set the environment variable GDFONTPATH for GD to find the fonts. 4. If you are using the cache please make sure that you have set the permissions correctly for the cache directory so that Apache/PHP can write to that directory. 5. Some windows installations seems to have a problem with a PHP script ending in a newline (This newline seems to be sent to the browser and will cause a Header already sent error). If you have this problem try remove all trailing newlines in the jpgraph* files Bug reports and suggestions --------------------------- Should be sent to (jpgraph aditus nu) [insert at and dot] Change history: ------------------------------------------------------------------------ Date Ver Comment ------------------------------------------------------------------------ 2004-06-20 1.16 Minor defect fixes 2004-05-04 1.15 Final 1.15 2004-04-19 1.15 BETA Defect fixes and code restructuring to make jpgraph.php smaller. 2003-11-25 1.14 Additional error checking, country flags, icon etc 2003-08-19 1.13 BETA Improved Gantt graphs various other changes and bug fixes 2003-02-02 1.11 Stock charts and some minor oter changes. 2002-12-16 1.10 Alpha blending, cubic splines and field plots 2002-10-30 1.9.1 Fixed two stupid mistakes in 1.9 2002-10-25 1.9 TTF font change.
