我有如下的 json 编码数据集（我使用 php 从 mYSQL 获取记录并转换为 json）

[{"CELL_NAME":"WELI01A","CI":1},{"CELL_NAME":"WELI02A","CI":2},{"CELL_NAME":"WELI02P","CI":3},{"CELL_NAME":"WELI02Q","CI":7},{"CELL_NAME":"WELI02B","CI":8},{"CELL_NAME":"COL001A","CI":11},{"CELL_NAME":"COL001B","CI":12},{"CELL_NAME":"COL001C","CI":13},{"CELL_NAME":"COL001P","CI":16},{"CELL_NAME":"COL001Q","CI":17},{"CELL_NAME":"COL001R","CI":18},{"CELL_NAME":"COL002A","CI":21},{"CELL_NAME":"COL002B","CI":22},{"CELL_NAME":"COL002C","CI":23},{"CELL_NAME":"COL002P","CI":26},{"CELL_NAME":"COL002Q","CI":27},{"CELL_NAME":"COL002R","CI":28},{"CELL_NAME":"COL003A","CI":31},{"CELL_NAME":"COL003B","CI":32},{"CELL_NAME":"COL003C","CI":33}]

我想用Echarts（百度）绑定上面的数据集，请在下面找到我的html代码

            },
            legend: {
                data:['Time','value']
            },
            toolbox: {

                feature : {

                    dataView : {show: true, readOnly: false},
                    magicType : {show: true, type: ['line', 'bar']},
                    restore : {show: true},
                    saveAsImage : {show: true}

            xAxis : [

                    data : field.CELL_NAME
                }
            ],
            yAxis : [
                {
                    type : 'value',
                    splitArea : {show : true}
                }
            ],
            series : [
                {
                    name:'Time',
                    type:'bar',
                    data:field.CI
                }
            ]
        });

    </script>

</body>
</html>

当我运行这个时，我只显示 json 输出，它不会弹出图表，请好心帮我排序

  1. xAxis.data应该是数组，series.data也是数组。

  2. 您应该首先格式化您的数据，然后将其作为参数传递给 myChart.setOption。

  3. 将 echarts.init 和 setOption 放在一个函数中会更好

  4. 这是一个例子
