Open flash chart中显示中文
open flash chart是一个在php中方便制图的工具包，关于open flash chart的使用和下载可以参考http://teethgrinder.co.uk/open-flash-chart/， 我们从2008年年初我们就开始用户open flash chart进行画图，但是一直不知道如何在flash中显示中文，最近open flash chart出了最新的2.0版本，里面提及了当open flash chart的数据文件采用的是UTF-8编码就能正常显示中文，我尝试了一下，确实如此。那么在版本1中修改数据文件的编码方式为UTF-8，然后输入中文，结果在flash中也是能正常显示中文的，唉，一年多一直不知道如何输入中文，原来就是一个编码的问题。
举一个1.0版本的例子：
我在linux下用vim编辑了一下如下文件，选择使用utf-8编码，然后将文件保存成pic.php，并从linux下拷贝出来，放到我们的windows服务器上，注意，中文部分在正常的文本编辑工具下显示的是乱码哦。

$dbname = 'ssss';
$conn = mssql_connect($servername,$username,$password) or die("couldn't open SQL Server $servername <br>");
$db = mssql_select_db($dbname,$conn) or die("couldn't open database $dbname <br>");
if( isset($_GET["enddate"]) && $_GET["enddate"]!="")
{
$enddate=$_GET['enddate'];
}
if( isset($_GET["startdate"]) && $_GET["startdate"]!="" && $_GET["startdate"]<$enddate)
{
$startdate=$_GET['startdate'];
}
else {
$startdate = $enddate;
}
$query = "select convert(varchar,a.thedate,112) as thedate,
pv,

order by thedate";
$result = mssql_query($query);
$thex0=array();

$MaxY1=0;
$MaxY2=0;
while($row = mssql_fetch_array($result))

array_push($thex0,$row["thedate"]);
array_push($pv,$row["pv"]);
array_push($uv,$row["uv"]);
}
$MaxY1 = max($pv);
$MaxY1 = 11*intval(round($MaxY1/10))+10;
$MaxY2 = max($uv);
$MaxY2 = 11*intval(round($MaxY2/10))+10;
$g = new graph();
$g->title( '鎵€鏈夋父鎴忕殑鐐瑰嚮閲?,'{font-size: 18px; color: #800000}' );
$g->set_x_labels($thex0 );
$g->set_x_label_style( 10, '0x000000', 2, 2 );
$g->set_data($pv);
$g->line_dot(3, 5, '0xFF00CC', 'PV', 10);
$g->set_data($uv);
$g->line_dot(3, 5, '0x00AACC', 'UV', 10);

$g->attach_to_y_right_axis(2);
$g->set_y_right_max($MaxY2);
$g->set_y_right_min(min($uv)-100);
$g->set_y_min(min($pv)-100);
$g->set_y_max($MaxY1 );
$g->y_label_steps( 5 );
echo $g->render();
?>
然后写一个调用这个数据文件的php脚本：
