时间：2008-01-11 来源：panzt
Open Flash Chart是一个开源的Flash图表显示类库，支持.Net,Java,PHP，Perl,Ruby等动态语言来构建动态的Flash数据图表。

OK，闲话少叙，看一个饼图的示例代码：
1、Chart.php
<?php
include_once 'php-ofc-library/open_flash_chart_object.php';
open_flash_chart_object( 200, 150, 'http://'. $_SERVER['SERVER_NAME'] .'/chart/chart-data.php', false );
?>
2、数据文件 chart-data.php
<?php
// generate some random data:
srand((double)microtime()*1000000);
$max = 50;
$data = array();
for( $i=0; $i<12; $i++ ){
$data[] = rand(0,$max);
}
// use the chart class to build the chart:
include_once( 'php-ofc-library/open-flash-chart.php' );
$g = new graph();
// Spoon sales, March 2007
$g->title( 'Spoon sales '. date("Y"), '{font-size: 26px;}' );
$g->set_data( $data );
// label each point with its value
$g->set_x_labels( array('Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec' ) );
// set the Y max
$g->set_y_max( 60 );
// label every 20 (0,20,40,60)
$g->y_label_steps( 6 );
// display the dataecho
$g->render();
?>
3.不要忘记将open-flash-chart.swf拷贝至根目录下
现在看来，基于数组的PHP有其自身强大的优势，也是其经久不衰的原因所在吧。
基于数组，换个想法，就是基于XML，再换个想法，就是基于简约格式的数据，正是这种简约带动了XML的流行，也推动了PHP的老树新春，所以简约就是时尚不是一句空话，是切切实实的真理。
闲话说完，看看另外两款基于XML作为数据源的Flash Chart
1、PHP/SWF Charts

简单示例：chart.php
<HTML>
<BODY bgcolor="#FFFFFF">
<?php
//include charts.php to access the InsertChart function
include "charts.php";
echo InsertChart ( "charts.swf", "charts_library", "sample.php", 400, 250 );
?>
</BODY>
</HTML>
sample.php
<?php
//include charts.php to access the SendChartData function
include_once("charts.php");
SendChartData ();
?>
