  .then((data) => {

    const { elements, width, height } = lottieParser.parse(data, {

      // 循环播放动画

      loop: true,

    });

    // Scale to 400px

    const scale = 400 / Math.min(width, height);

    chart.setOption({

      graphic: {

        elements: [

          {

            type: 'group',

            scaleX: scale,

            scaleY: scale,

            // Elements is compatitable with echarts graphic.
