上圖爲pchart 繪出，本人之所以寫這個文章，是希望能有更多的user來使用pchart，這樣pchart也會出更多的代碼！
繪圖的數據時直接從公司的wiki網站的mysql上抓的（因爲網站也是我自己架設的，所以可以直接抓到相關的數據）！
wiki的mysql中數據比較的亂，有很多的html標籤，如果只是使用一次是沒有什麼問題的，但是如果經常使用這些數據繪製不同的圖標，就會自己都覺得很煩！
本人做法：現將wiki的mysql 數據處理並導入到新的MySQL中，然後在利用新的mysql和pchart來畫圖！
代碼如下，有問題的可以留言！
處理wiki 並導入新的mysql代碼：
<?php
$did = 804; //sa grid
$wyear = 2014;
$connect=new mysqli("localhost","pchart","????","pchartdb");
if(mysqli_connect_errno()){

exit;

exit;
}

$thismonth=$thismonth;
$sql_report = "select title,content from wiki_doc where did='$did'";
$result=$mysqli->query($sql_report);
$sql_result = $result->num_rows;
#print_r($sql_result);
for($i=0;$i<=$sql_result;$i++){
$rows=$result->fetch_assoc();

} pchart 畫圖代碼：
