OpenFlashChart使用之线性图表典型使用例子，使用swfobject.js将html图表代码写入到id="my_chart"的DIV中，效果如下：
html代码：
<html>
<head>
<scripttype="text/javascript"src="js/swfobject.js"></script>
<scripttype="text/javascript">
swfobject.embedSWF(
"open-flash-chart.swf", "my_chart",
"600", "350", "9.0.0", "expressInstall.swf",
{"data-file":"gallery/x-legend.php"} );
</script>
</head>
<body>
<p>Hello World</p>
<divid="my_chart"></div>
</body>
</html>
x-legend.php代码如下：
<?php
include'../php-ofc-library/open-flash-chart.php';
$year = array();
$price = array();
$year[] = '1983'; $price[] = 36.7;
$year[] = '1984'; $price[] = 38.7;
$year[] = '1985'; $price[] = 42.8;
$year[] = '1986'; $price[] = 38.2;
$year[] = '1987'; $price[] = 37.8;
$year[] = '1988'; $price[] = 34.7;
$year[] = '1989'; $price[] = 38.4;
$year[] = '1990'; $price[] = 40.2;
$year[] = '1991'; $price[] = 39.5;
$year[] = '1992'; $price[] = 40.3;
$year[] = '1993'; $price[] = 45.9;
$year[] = '1994'; $price[] = 48.9;
$year[] = '1995'; $price[] = 50.9;
$year[] = '1996'; $price[] = 52.9;
$year[] = '1997'; $price[] = 57.9;
$year[] = '1998'; $price[] = 60.9;
$year[] = '1999'; $price[] = 61.9;
$year[] = '2000'; $price[] = 76.9;
$year[] = '2001'; $price[] = 77.9;
$year[] = '2002'; $price[] = 69.9;
$year[] = '2003'; $price[] = 77.9;
$year[] = '2004'; $price[] = 77.9;
$year[] = '2005'; $price[] = 79.9;
$year[] = '2006'; $price[] = 88.9;
$year[] = '2007'; $price[] = 87.9;
$year[] = '2008'; $price[] = 103.9;
$chart = new open_flash_chart();
$title = new title( 'UK Petrol price (pence) per Litre' );
$title->set_style( "{font-size: 20px; color: #A2ACBA; text-align: center;}" );
$chart->set_title( $title );
$area = new area();
$area->set_colour( '#5B56B6' );
$area->set_values( $price );
$area->set_key( 'Price', 12 );
$chart->add_element( $area );
$x_labels = new x_axis_labels();
$x_labels->set_steps( 2 );
$x_labels->set_vertical();
$x_labels->set_colour( '#A2ACBA' );
$x_labels->set_labels( $year );
$x = new x_axis();
$x->set_colour( '#A2ACBA' );
$x->set_grid_colour( '#D7E4A3' );
$x->set_offset( false );
$x->set_steps(4);
// Add the X Axis Labels to the X Axis
$x->set_labels( $x_labels );
$chart->set_x_axis( $x );
//
// LOOK:
//
$x_legend = new x_legend( '1983 to 2008' );
$x_legend->set_style( '{font-size: 20px; color: #778877}' );
$chart->set_x_legend( $x_legend );
//
// remove this when the Y Axis is smarter
//
$y = new y_axis();
$y->set_range( 0, 150, 30 );
$chart->add_y_axis( $y );
echo$chart->toPrettyString();
注意：如果不能正常显示图表请检查 swfobject.js 和x-legend.php的引用路径是否正确（html代码中的 第4行和第10行）
