看下代码

HTML页面 为ECharts准备一个Dom,宽高自定义

<div class="panel panel-info">
  <div class="panel-body">
    <div id="echart_show" style="height:500px"></div>
  </div>
</div>

js文件可以参考官网,或者在这里下载,引入

<script type="text/javascript" src="路径/lib/jquery/nowdatachars/echarts-all.js"></script>

下面是具体方法

<script type="text/javascript">
var date = [],num = [];
$(document).ready(function () {
    // 绘制反馈量图形
    var init_echarts = function () {
        var refreshChart = function (show_data) {
            my_demo_chart = echarts.init(document.getElementById('echart_show'));
            my_demo_chart.showLoading({
                text: '加载中...',
                effect: 'whirling'
            });
            var echarts_all_option = {
                title: {
                    text: '',
                    subtext: '用户走势'
                },
                tooltip: {
                    trigger: 'axis'
                },
                legend: {
                    data: ['用户数', '用户消耗']
                },
                toolbox: {
                    show: true,
                    feature: {
                        mark: {show: true},
                        dataView: {show: true, readOnly: false},
                        magicType: {show: true, type: ['line', 'bar']},
                        restore: {show: true},
                        saveAsImage: {show: true}
                        // myTool2: {
                        //     show: true,
                        //     title: '自定义扩展方法',
                        //     icon: 'image://http://echarts.baidu.com/images/favicon.png',
                        //     onclick: function (){
                        //         alert('自定义')
                        //     }
                        // }
                    }
                },
                dataZoom: {
                    show: false,
                    start: 0,
                    end: 100
                },
                xAxis: [
                    {
                        type: 'category',
                        boundaryGap: true,
                        data: show_data[1]
                    },
                    {
                        type: 'category',
                        boundaryGap: true,
                        data: show_data[1]
                    }
                ],
                yAxis: [
                    {
                        type: 'value',
                        scale: true,
                        name: '用户数',
                        boundaryGap: [0, 0.5]
                        // boundaryGap: [0.2, 0.2]
                    },
                    {
                        type: 'value',
                        scale: true,
                        name: '用户数',
                        boundaryGap: [0, 0.5]
                    }
                ],
                series: [
                    {
                        name: '用户消耗',
                        type: 'bar',
                        xAxisIndex: 1,
                        data: show_data[0]
                    },
                    {
                        name: '用户数',
                        type: 'line',
                        xAxisIndex: 1,
                        data:show_data[0]
                    }
                ]
            };
            my_demo_chart.hideLoading();
            my_demo_chart.setOption(echarts_all_option);
        }; 
        // 获取原始数据
        $.ajax({
            url:"__CONTROLLER__/getRes",
            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);
                        msg[0] = num;
                        msg[1] = date;
                        refreshChart(msg);
                    }
                }
            }
        });
    };
    // 默认加载
    var default_load = (function () {
        init_echarts();
    })();
});
</script>

控制器中查询自己需要的数据 (这里查询的日期和对应的数量)

//折线统计
public function getRes(){
    $user = M('account');
    $sql = "SELECT date(createTime) AS date,count(*) as count FROM t_account  GROUP BY date ";
    $result = $user->query($sql);
    $this->ajaxReturn(array('code'=>200,'result'=>$result));
}

至此,一个简单的echarts的统计图就出来了

对echarts中一些参数不太理解的,大家可以参考官网 https://www.echartsjs.com/option.html#title
