echarts 统计直线图

1. 使用echarts 实例:

<script type="text/javascript">
    var date = "<?= $date?>";
    var new_students = "<?= $new_students?>";
    var total_students = "<?= $total_students?>";
    date = date.split(",");
    new_students = new_students.split(",");
    total_students = total_students.split(",");
    console.log(total_students[1]);

    var myChart = echarts.init(document.getElementById('main'));

    // 指定图表的配置项和数据
    var option = {
        title: {
            text: ''
        },
        tooltip: {
            trigger: 'axis'
        },
        legend: {
            data:['新增医生','医生总人数']
        },
        grid: {
            left: '3%',
            right: '4%',
            bottom: '3%',
            containLabel: true
        },
        toolbox: {
            feature: {
                saveAsImage: {}
            }
        },
        xAxis: {
            type: 'category',
            boundaryGap: false,
            data: [date[0],date[1],date[2],date[3],date[4],date[5],date[6],]
        },
        yAxis: {
            type: 'value'
        },
        series: [
            {
                name:'新增医生',
                type:'line',
                // stack: '总量',
                data:[new_students[0],new_students[1],new_students[2],new_students[3],new_students[4],new_students[5],new_students[6]]
            },
            {
                name:'医生总人数',
                type:'line',
                // stack: '总量',  如果不删除 则计算的是累计
                data:[total_students[0],total_students[1],total_students[2],total_students[3],total_students[4],total_students[5],total_students[6]]
            }
        ]
    };

        // 使用刚指定的配置项和数据显示图表。
        myChart.setOption(option);
</script

stack  如果使用则是累计统计数,根据情况设置 ，如不需要则不添加
