1.To support Chinese, you need to useSimhei.ttfand theSIMSUN.TTCthe two fonts,When you use Chinese, you need to useSetFont (ff_simsun,fs_bold)sets the font. put the required fonts into the Src\fonts\ directory under the project directory in jpgraph.php , there is the following code that sets the font file path ////Setup path for western/latin TTF fonts//if (!defined (' Ttf_dir ')) {if (strstr (Php_os, ' WIN ')) {$sroot = getenv (' SystemRoot ');if (empty ($sroot)) {$t = new Errmsgtext ();$msg = $t->get ($file, $lineno);Die ($msg); }else {define (' Ttf_dir ', $sroot. ' /fonts/'); }} else {define (' Ttf_dir ', '/usr/share/fonts/truetype/'); }} 2. It is important to note that: to applyJpgraph, you havePHPmust be turned on.GD2extension.
If you want to modify the path of the file first, under Window
Modify the jpgraph_ttf.inc.php file$jpgraph _font_dir = dirname (__file__). ' \\fonts\\ ';//change the path of the font from the original/fonts/to \\fonts\\ if not modified under Windows will report the following error
To solve the Chinese problem:If your file is encoded asUtf-8, modify the method as follows
method One:Find ElseIf ($aFF = = = Ff_simsun) { //do Chinese convers ion if ($this->g2312 = = null) { &NBS P include_once ' jpgraph_gb2312.php '; $this->g2312 = new GB 2312toutf8 (); } return $this->g2312-& Gt;gb2utf8 ($ATXT); } modified to ElseIf ($aFF = = = Ff_simsun) { & nbsp //do Chinese conversion /* &NBSP ; if ($this->g2312 = = null) { include_once ' jpgraph_gb2312 . php '; $this->g2312 = new Gb2312toutf8 (); & nbsp } return $this->g2312->gb2utf8 ($ATXT); &N Bsp */ return $aTxt; }
Method Two: modify in the program $title = "Flow Chart";
$title = Iconv ("UTF-8", "gb2312", $title);
$graph->title->set ($title);
Note:JpgraphThe default display of Chinese characters is to think of Chinese character codinggb2312,translates toUtf-8Show again later.
in that case, if your file code isGb2312,setfontthe first parameter of a method isFf_simsuncan be.
If you areUtf-8coding You also need to convert Chinese character coding intogb2312so that your characters can be displayed normally.
The code is as follows:
<?php/** * Generate 3D pie chart using jpgraph * */include ' src/jpgraph.php '; include ' src/jpgraph_pie.php '; include ' Src/jpgraph_ Pie3d.php ';//Refer to the class file containing the 3D pie Pieplot3d Object
$result = Array (5,8,11,1,1,1), $vote _content = Array ("Zhang San", "Lili", "Lili", "Zhang San", "Lili", "Lili"); $title = ' title ';
$graph = new Piegraph (500,245);//Create Image $graph->setshadow ();//Create Image Shadow $graph->tabtitle->setfont (Ff_simsun,fs_ bold,14);//Set Caption Font $graph->tabtitle->set ($title);//Output title $graph->title->setcolor ("Darkblue");//define title color
