PHP如何使用Echarts生成数据统计报表

echarts统计，简单示例

推荐：《PHP视频教程》

先看下效果图

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="__ROOT__/Public/admin/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(&#39;echart_show&#39;));

                my_demo_chart.showLoading({
                    text: &#39;加载中...&#39;,
                    effect: &#39;whirling&#39;
                });

                var echarts_all_option = {
                    title: {
                        text: &#39;&#39;,

                            xAxisIndex: 1,
                            data: show_data[0]
                        },
                        {
                            name: &#39;用户数&#39;,
                            type: &#39;line&#39;,
                            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:&#39;json&#39;,
                type:&#39;post&#39;,

                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
