先上一張效果圖

這邊用的是echarts外掛http://echarts.baidu.com/

上程式碼（小白寫的 別追求什麼屌逼程式碼，就是冗餘的面向過程，不服你來咬我）

<div>
	<button onclick="zhou()" class="btnweek week active" style="margin-left: 300px">按周排</button><button onclick="yue()" class="btnweek month" style="margin-left: 100px">按月排</button>
</div>

		<!-- 為 ECharts 準備一個具備大小（寬高）的 DOM -->
    	<div id="main" style="width: 95%;height:400px;"></div>
    	<script type="text/javascript">
