如何使用php在我的管理面板中繪製統計線圖？

我想用GD庫使用PHP來顯示我的表在我的管理面板.. 我得到的日期從我的數據庫，但是當我使用任何庫顯示此結果線圖也沒有工作&它沒有顯示任何錯誤。我不明白我做錯了什麼？任何人都可以幫助我嗎？如何使用php在我的管理面板中繪製統計線圖？

<?php 
include ("../setting.php"); 
include("../classes/phpgraphlib.php"); 


$result = mysql_query("SELECT DATE_FORMAT(log_date, '%Y-%m-%d') as Date,count(*) as Count FROM log 
where operation_type='Add' and user_id='82' and faculty_code='0' group by log_date order by log_date") or die(mysql_error()); 

$MultiDimArray = array(); 
$data = array(); 

while($row = mysql_fetch_array($result , MYSQL_BOTH)) 
{ 
$MultiDimArray[] = array ('Date' => $row['Date'], 'Count' => $row['Count']); 

} 


foreach($MultiDimArray as $value) 
{ 
    if (!array_key_exists($value['Date'], $data)) { 
     $data[$value['Date']] = $value['Count']; 
    } 
    else{ $data[$value['Date']] += (string)$value['Count'];} 
} 
$data = array_map('strval', $data); 

$graph = new PHPGraphLib(400,300); 
$graph->addData($data); 
$graph->setTitle("Site Statistics"); 
$graph->setBars(false); 
$graph->setLine(true); 
$graph->setDataPoints(true); 
$graph->setDataPointColor("maroon"); 
$graph->setDatadata(true); 
$graph->setDataValueColor("maroon"); 
$graph->setGoalLine(.0025); 
$graph->setGoalLineColor("red"); 
$graph->setXdataHorizontal(true); 
$graph->createGraph(); 

?> `

$數據陣列的輸出是這樣的：

array'2013-05-13' => string '7' (length=1)'2013-05-15' => string '3' (length=1)'2013-05-16' => string '5' (length=1)'2013-05-18' => string '8' (length=1)'2013-05-19' => string '2' (length=1)'2013-05-21' => string '2' (length=1)'2013-05-22' => string '10' (length=2)'2013-05-23' => string '2' (length=1)'2013-05-25' => string '1' (length=1)'2013-05-26' => string '8' (length=1)'2013-05-27' => string '19' (length=2)'2013-05-28' => string '7' (length=1)'2013-05-29' => string '3' (length=1)'2013-06-02' => string '11' (length=2)'2013-06-03' => string '2' (length=1)'2013-06-04' => string '7' (length=1)'2013-06-05' => string '3' (length=1)'2013-06-06' => string '2' (length=1)'2013-06-09' => string '15' (length=2)'2013-06-10' => string '5' (length=1)'2013-06-11' => string '1' (length=1)'2013-06-12' => string '3' (length=1)'2013-06-15' => string '10' (length=2)'2013-06-16' => string '3' (length=1)'2013-06-19' => string '2' (length=1)

考慮標記，並在標題提的GD庫。 – Jonast92

啓用錯誤報告或查看您的服務器日誌。 – str

我建議使用JS的是，從PHP數據餵養它。看看Flot或類似的東西。
