The project was written due to a need for a high resolution graph class at the office and released to the public domain under the GPL license to repay others for the software we ourselves have used free of charge.Requirements:· PHP 4+· Bundled GD· Some TTF fonts (not included for space reasons)Usage examples:Basic usage. require_once('phpGraphEd/phpGraphEd.php');$graphEd = new phpGraphEd();// Set graph options$graphEd->backgroundSetColor(200, 200, 200, 0); // Otherwise the background is transparent// Set graph data$graphEd->titleSet('Is PHPGraphEd impressive?');$graphEd->dataAdd('Yes', rand(0, 12));$graphEd->dataAdd('No', rand(0, 20));$graphEd->dataAdd('Undecided', rand(5, 10));// Render the graph$image = $graphEd->render();// Output it to the browserheader("Content-type: image/png");imagepng($image);Groups in the graph. require_once('phpGraphEd/phpGraphEd.php');$graphEd = new phpGraphEd();// Set graph options$graphEd->backgroundSetColor(200, 200, 200, 0); // Otherwise the background is transparent// Set graph data$graphEd->titleSet('Is PHPGraphEd impressive?');$graphEd->dataAdd('Yes', rand(0, 12), 'Men');$graphEd->dataAdd('No', rand(30, 35), 'Women');$graphEd->dataAdd('No', rand(0, 20), 'Men');$graphEd->dataAdd('Undecided', rand(1, 20), 'Children');$graphEd->dataAdd('Undecided', rand(5, 10), 'Men');// Render the graph$image = $graphEd->render();// Output it to the browserheader("Content-type: image/png");imagepng($image);Changing most settings. require_once('phpGraphEd/phpGraphEd.php');$graphEd = new phpGraphEd();$graphEd->fontBaseDirectory('/usr/share/fonts/ttf/'); // Include fonts from this directory instead. $graphEd->sizeSet(1000, 500); // Pixels. Standard size is 1024x768$graphEd->fontScaling(1.2); // Scale the fonts and border widths etc. Use higher values than 1.0 // to make printable graphs. For example: 3000x2000 and 2.0$graphEd->backgroundSetImage('../images/background-main.jpg'); // Should probably be a file that actually exists...$graphEd->backgroundSetType('tile'); // Tile the background image$graphEd->titleSet('Is PHPGraphEd impressive?');$graphEd->axisFormat('*VALUE*'); // Show the axis as values, not percentages.$graphEd->dataAdd('Yes', rand(0, 6), 'Men');$graphEd->dataAdd('Yes', rand(12, 20), 'Women');$graphEd->dataAdd('Yes', rand(6, 12), 'Children');$graphEd->dataAdd('No', rand(0, 20), 'Men');$graphEd->dataAdd('No', rand(20, 35), 'Women');$graphEd->dataAdd('Undecided', rand(5, 10), 'Men');$graphEd->dataAdd('Undecided', rand(0, 10), 'Women');$graphEd->dataAdd('Undecided', rand(1, 20), 'Children');// Render the graph$image = $graphEd->render();// Output it to the browserheader("Content-type: image/jpeg"); // Graphs with image backgrounds are smaller with jpgimagepng($image, null, 90);What's New in This Release:· legendFont, legendFontColor, XFont, XFontColor, YFont, YFontColor, titleFontShadowColor, and Bar label split automatically.
