jpgraph 设置X轴点

<?php
require_once ('jpg/jpgraph.php');
require_once ('jpg/jpgraph_line.php');
require_once ('jpg/jpgraph_date.php');

$datay = array( 10,80,20,80,11,5,22,20.20,44.255 );
DEFINE('NDATAPOINTS',3600);
DEFINE('SAMPLERATE',2);
$start = time();
$end = $start+NDATAPOINTS*SAMPLERATE;

$graph = new Graph(1200,600);
$graph->SetMargin(40,40,30,130);
$graph->SetScale('datlin',0,200);
$graph->xaxis->SetLabelAngle(0);

$line = new LinePlot( $datay );
$line->SetFillColor('lightred@0.5');

$line->mark->SetType( MARK_FILLEDCIRCLE );
$line->mark->SetFillColor( 'red' );
$line->mark->SetWidth( 4 );
$line->SetColor( 'red' );
$line->SetCenter();

$graph->Add($line);
$graph->Stroke();
?>

以上是代码。。。。。。。。。。。。。。。。。。。
问题来了 : 怎么设置X轴每隔10分钟显示一个轴点，谢谢！

由于写一些小东西需要生成柱状图,决定jpgraph来生成图像,可结果不是很理想,因为标题是中文,出现了乱码,顺手问了度娘一下,结果没看到我想要的答案,最后求助于谷歌,解决了大半问题…解决如下:

1)修改jpgraph_ttf.inc.php,找到185行:elseif( $aFF === FF_SIMSUN ) {这里,代码如下:
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);
