一、下載echarts插件，下載地址：http://echarts.baidu.com/javascript

二、具體入門案例就不囉嗦了，參考官方教程：http://echarts.baidu.com/tutorial.htmlhtml

三、前臺引入echarts和jquery，ajax請求相應的json數據java

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>ECharts</title>
    <!-- 引入 echarts.js -->  
    <script src="__ROOT__/Public/jquery-1.10.2.min.js"></script>
    <script src="__ROOT__/Public/echarts.common.min.js"></script>
</head>
<body>
    <!-- 爲ECharts準備一個具有大小（寬高）的Dom -->
    <div id="main" style="width: 1200px;height:400px;"></div>
    <script type="text/javascript">
        // 基於準備好的dom，初始化echarts實例
        var myChart = echarts.init(document.getElementById('main'));
        // 指定圖表的配置項和數據
        var date = [],num = [];
        function getNumber(){
            $.ajax({
                url:"__CONTROLLER__/getRegister",
                async:false,
                dataType:'json',
                type:'post',
                success:function(msg){
                    var result = msg.result;
                    if(msg.code == 200){
                        for(var i = 0 ; i < result.length; i++){
                            date.push(result[i].date);
                            num.push(result[i].count);
                        }
                    }
                }
            });
        };
        getNumber();
    option = {
    title: {
        text: '近期註冊走勢'
    },
    tooltip: {
        trigger: 'axis'
    },
    legend: {
        data:['註冊數']
    },
    grid: {
        left: '3%',
        right: '4%',
        bottom: '3%',
        containLabel: true
    },
    toolbox: {
        feature: {
            saveAsImage: {}
        }
    },
    xAxis: {
        type: 'category',
        boundaryGap: false,
        data: date
    },
    yAxis: {
        type: 'value'
    },
    series: [
        {
            name:'註冊數',
            type:'line',
            stack: '總量',
            data:num
        },
    ]
};
        // 使用剛指定的配置項和數據顯示圖表。
        myChart.setOption(option);
    </script>
</body>
</html>

四、後臺接口返回json數據jquery

public function getRegister(){
        $user = D('User');
        $beginLastweek=strtotime('-30 days');
        //兩週前的時間戳
        $begin = strtotime(date('Y-m-d',$beginLastweek));
        $result = $user->field("register_time")->where("register_time > '%s'",$begin)->select();
        $sql = "SELECT FROM_UNIXTIME( register_time, '%Y-%m-%d' ) AS date,count(*) as count FROM app_user WHERE register_time > $beginLastweek GROUP BY register_time div 86400;";
        $result = $user->query($sql);
        $this->ajaxReturn(array('code'=>200,'result'=>$result));
    }
