百度echarts实现散点图

echarts版本：4.1.0；

html代码：

<div id="countScatter" style="height: 500px;"></div>

JS代码:

<script type="text/javascript">
    $(function () {
        initChart();
    });

    /*图表生成*/
    function initChart() {
        var data = [];
        $.ajax({
            url: context + "/service/queryApplyStatistics/countDsInfoQueryTimesOnlyByDeptData",
            async: false,
            dataType: "json",
            data: {"startDate": $('#startDate').val(), "endDate": $('#endDate').val()},
            type: "GET",
            success: function (countData) {
                $.each(countData, function (index, value) {
                    var tempData = [];
                    tempData.push(value.APPLY_DEPT_NAME);
                    tempData.push(Number(value.COUNT_NUM));
                    data.push(tempData);
                })
            }
        });
        console.log(data);
        var scatterChart = echarts.init(document.getElementById('countScatter'));
        option = {
            tooltip: {},
            xAxis: {type:'category'},
            yAxis: {type:'value'},
            series: [{
                symbolSize: 20,
                data:data,
                type: 'scatter'
            }]
        };

        scatterChart.setOption(option);
    }
</script>

后台得到的数据格式为：

[['测试部门1',1],['省院案件管理室',5],['测试部门2',0]]
