下載
在官方網站?http://www.aditus.nu/jpgraph/?下載jpgraph，其中1.X系列是用于PHP4的，2.X系列是用于PHP5的。

安裝
將下載的得到的jpgraph壓縮文件解壓至相應的路徑。 配置
首先需要注意的是：要想適用jpgraph，你的PHP必須開啟了GD2擴展。
在jpgraph.php中有以下這樣一段代碼是設置字體文件路徑的
if (!defined('TTF_DIR')) { if (strstr( PHP_OS, 'WIN') ) { $sroot = getenv('SystemRoot'); if( empty($sroot) ) { $t = new ErrMsgText(); $msg = $t->Get(12,$file,$lineno); die($msg); } else { define('TTF_DIR', $sroot.'/fonts/'); } } else { define('TTF_DIR','/usr/share/fonts/truetype/');??(我的作法是將windows下的fonts文件夾下的字體全部COPY到/usr/local/fonts/truetype) } }

要支持中文需要用到simhei.ttf和simsun.ttc這兩個字體,在使用中文的時候需要使用SetFont(FF_SIMSUN,FS_BOLD)設置字體。
?
如果你的文件編碼為utf-8,修改方法如下：
代碼：
方法一，在程序中修改
$title="流量圖";
$title = iconv("UTF-8", "gb2312", $title);
$graph->title->Set($title);
方法二，修改源文件jpgraph_ttf.inc.php
在第99-106行，改成下面這樣子
?? ?elseif( $aFF === FF_SIMSUN ) {
?? ???? // Do Chinese conversion
??????? /*
?? ???? if( $this->g2312 == null ) {
?? ??? ?include_once 'jpgraph_gb2312.php' ;
?? ??? ?$this->g2312 = new GB2312toUTF8();
?? ???? }
?? ???? return $this->g2312->gb2utf8($aTxt);
??????? */
?? ??? ?return $aTxt;
?? ?}

jpgraph默認顯示漢字時是把漢字編碼認為gb2312,轉化為utf-8以后再顯示。
這樣的話，如果你的文件編碼是gb2312,SetFont方法的第一個參數為FF_SIMSUN即可。
如果你是utf-8編碼你還需要先把漢字編碼轉化為gb2312，這樣你的漢字才可以正常顯示。

使用
可以參照jpgraph-2.3.4\src\Examples中的例子。下面是一些常用的：
$graph->title->Set(‘設置圖表的標題’);
$graph->xaxis->title->Set("設置X軸的標題");
$graph->yaxis->title->Set("設置Y軸的標題");

//設置字體?如果是中文，第一個參數一般設置為FF_SIMSUN
SetFont(FF_SIMSUN,FS_BOLD,14);
//如設置圖表標題的字體
$graph->title->SetFont(FF_SIMSUN,FS_BOLD,14);

//設置顏色
SetColor('red'); Example:
