动态绑定百度echarts数据失败，求解？

[zhu5152]

用了百度echarts图表作图 动态绑定的时候横轴数据绑定失败！！ 是通过后台ajax传输json绑定的。

$(function () {
		        var myCharts = echarts.init(document.getElementById("main"));
		        var sAccNum = document.getElementById("lblInAcc").innerText;
		        var option = {
		            title: {
		                text: ''
		            },
		            tooltip: {
		                trigger: 'axis'
		            },
		            legend: {
		                data: ['消费金额']
		            },
		            grid: {
		                left: '3%',
		                right: '4%',
		                bottom: '3%',
		                containLabel: true
		            },
		            xAxis: {
		                type: 'category',
		                boundaryGap: false,
		                //data: ["2017-09-27", "2017-09-28", "2017-09-29", "2017-09-30", "2017-10-01", "2017-10-02", "2017-10-03", "2017-10-04", "2017-10-05", "2017-10-06", "2017-10-07", "2017-10-08", "2017-10-09", "2017-10-10", "2017-10-11", "2017-10-12", "2017-10-13", "2017-10-14", "2017-10-15", "2017-10-16", "2017-10-17", "2017-10-18", "2017-10-19", "2017-10-20", "2017-10-21", "2017-10-22", "2017-10-23", "2017-10-24", "2017-10-25", "2017-10-26"]
		            data:[]
                    },
		            yAxis: {
		                type: 'value'
		            },
		            series: []
		        };
		        $.ajax({
		            type: 'post',
		            url: 'ConsData.aspx?sAccNum=' + sAccNum,
		            data: {},
		            dataType: 'json',
		            async: false,
		            success: function (result) {
		                if (result) {
		                    // 获取json值
		                    option.series = result.series;

		                    option.xAxis[0].data = result.category
		                   
		                    // 为echarts对象加载数据 
		                    myCharts.setOption(option);
		                }
		            },
		            error: function () {
		                alert("Error");
		            }
		        });
		    })

这是前端代码
后台json数据：
{"category":["2017-09-27","2017-09-28","2017-09-29","2017-09-30","2017-10-01","2017-10-02","2017-10-03","2017-10-04","2017-10-05","2017-10-06","2017-10-07","2017-10-08","2017-10-09","2017-10-10","2017-10-11","2017-10-12","2017-10-13","2017-10-14","2017-10-15","2017-10-16","2017-10-17","2017-10-18","2017-10-19","2017-10-20","2017-10-21","2017-10-22","2017-10-23","2017-10-24","2017-10-25","2017-10-26"],
"series":[{"name":"消费金额","type":"line","itemStyle":{"normal":{"color":"#0099FF"}},
"data":[0.0,-20.0,-112.0,0.0,0.0,0.0,0.0,-50.0,0.0,0.0,-26.0,0.0,-2.0,-1.0,0.0,-2.0,0.0,0.0,0.0,-14.0,-16.0,-517.0,0.0,0.0,0.0,0.0,-14.0,0.0,0.0,0.0]}]}

option.xAxis[0].data = result.category 这句话好像无法绑定横轴数据 然后图表无法展示，纵轴数据是成功绑定的（测过）。

如果 xAxis属性 写成静态的话 图表就没问题了 但是动态获取横轴坐标数据 就会有问题 是数据的原因么？

有demo吗？可以看看啊

人家是对象 你[0]从哪里来的? ....

[正怒月神]

你直接把category的数据写死在data里。能跑吗？ 如果不行，说明你的category和data的数据不匹配。 如果可以，那你看看category是不是缺少转换之类的问题

[zhu5152]

我把数据负数改成正数的然后就没问题了 然后把[0] 去掉

从网上demo里参考的.....现在已经解决了。。谢谢了
