上圖爲pchart 繪出，本人之因此寫這個文章，是但願能有更多的user來使用pchart，這樣pchart也會出更多的代碼！php

繪圖的數據時直接從公司的wiki網站的mysql上抓的（由於網站也是我本身架設的，因此能夠直接抓到相關的數據）！html

wiki的mysql中數據比較的亂，有不少的html標籤，若是隻是使用一次是沒有什麼問題的，可是若是常常使用這些數據繪製不一樣的圖標，就會本身都以爲很煩！mysql

本人作法：現將wiki的mysql 數據處理並導入到新的MySQL中，而後在利用新的mysql和pchart來畫圖！sql

代碼以下，有問題的能夠留言！數組

處理wiki 並導入新的mysql代碼：ide
