Auxiliary and extended functions rgb.inc.php . . . . . . . . . . Optional extended color table REQUIREMENTS: You need a recent version of PHP: 4.3.0 or higher. You are advised to use the latest stable release of PHP 4. (Testing with PHP 5 is not complete at this time.) You need the GD extension to PHP either built in to PHP or loaded as a module. Refer to the PHP documentation for more information - see the Image Functions chapter in the PHP Manual. If you want to display PHPlot charts on a web site, you need a PHP-enabled web server. You can also use the PHP CLI interface without a web server. If you want to use TrueType fonts on your charts, you need to have TrueType support in GD, and some TrueType font files. PHPlot does not include any TrueType font files. By default, PHPlot uses a simple built-in font. INSTALLATION: Unpack the distribution. (If you are reading this file, you have probably already done that.) Installation of PHPlot simply involves copying three script files somewhere your PHP application scripts will be able to find them. The scripts are: phplot.php phplot_data.php rgb.inc.php (Only phplot.php is necessary for most graphs.) Make sure the protections on these files allow the web server to read them. The ideal place is a directory outside your web server document area, and on your PHP include path. You can add to the include path in the PHP configuration file; consult the PHP manual for details. TESTING: You can test your installation by creating the following two files somewhere in your web document area. First, the HTML file: ------------ simpleplot.html ---------------------------- Hello, PHPlot!

PHPlot Test

--------------------------------------------------------- Second, in the same directory, the image file producing PHP script file. Depending on where you installed phplot.php, you may need to specify a path in the 'require' line below. ------------ simpleplot.php ----------------------------- SetDataValues($data); $plot->SetDataType('data-data'); $plot->DrawGraph(); --------------------------------------------------------- Access the URL to 'simpleplot.html' in your web browser. If you see a simple graph, you have successfully installed PHPlot. If you see no graph, check your web server error log for more information.
