Echarts属性通过定时器实现动画效果的研究（柱图）

 var dom = document.getElementById("container");
    var myChart = echarts.init(dom);
    var option = {
        backgroundColor: '#080b30',
        xAxis: {

            show: false,
            type: 'value'
        },
        series: [{
            data: [120, 200, 150, 80, 70, 110, 130],
            type: 'bar',
            barWidth: "30%",
            itemStyle: {
                barBorderRadius: [10, 10, 0, 0]
            }
        }]

    myChart.setOption(option, true);

    var arr = [0, 1];
    var i = 0;
    var t = setInterval(show, 2000);
    //变色;
    var colorList = ['#ff7f50', '#87cefa'];
    function show() {

                    shadowColor: 'rgba(255,255, 255, 0.8)',//阴影颜色
                    shadowBlur: arr[i] * 30,//阴影的模糊大小
                }
