如何将mysql 统计数据 输出 echart

你把你的数组返回值中间用个符号分割，比如分号["a1","b1"]["a2"',"b2"]，然后用split{""}进行分割就可以分开使用了。 var t = "['a1','b1']['a2'','b2']"var ts = t.split("")alert(ts[0])alert(ts[1])下面这个写法写错了 function...

var myChart

        //创建ECharts图表方法

        function DrawEChart(ec) {

            //--- 折柱 ---

            myChart = ec.init(document.getElementById('main'))

            //图表显示提示信息

            myChart.showLoading({

                text: "图表数据正在努力加载..."

            })

            //定义图表options

            var options = {

                title: {

                    text: "通过Ajax获取数据呈现图标示例",

                    subtext: "www.stepday.com",

                    sublink: "http://www.stepday.com/myblog/?Echarts"

                },

                tooltip: {

                    trigger: 'axis'

                },

                legend: {

                    data: []

                },

                toolbox: {

                    show: true,

                    feature: {

                        mark: false

                    }

                },

                calculable: true,

                xAxis: [

                    {

                        type: 'category',

                        data: []

                    }

                ],

                yAxis: [

                    {

                        type: 'value',

                        splitArea: { show: true }

                    }

                ],

                series: []

            }

            //通过Ajax获取数据

            $.ajax({

                type: "post",

                async: false, //同步执行

                url: "/Ajax/GetChartData.aspx?type=getData&count=12",

                dataType: "json", //返回数据形式为json

                success: function (result) {

                    if (result) {                        

                        //将返回的category和series对象赋值给options对象内的category和series

                        //因为xAxis是一个数组 这里需要是xAxis[i]的形式

                        options.xAxis[0].data = result.category

                        options.series = result.series

                        options.legend.data = result.legend

                        myChart.hideLoading()

                        myChart.setOption(options)

                    }

                },

                error: function (errorMsg) {

                    alert("不好意思，大爷，图表请求数据失败啦!")

                }

            })

        }
