           this.registeredChart = echarts.init(
             document.getElementById("registered")
           );
           var options = {
             grid: {
               top: "10%",
               left: "7.5%",
               right: "1%",

             },
             tooltip: {
               trigger: "axis",
             },
             xAxis: {
               type: "category",
               data: x,
               axisLabel: {
                 textStyle: {
                   color: "#3FDDFF",
                 },
               },
               show:false, // don't show the axis, axis tick marks and text on the axis
             },
             yAxis: {

               splitLine: {
                 how: true,
                 lineStyle:{
                   color: ['#2d2e4850'],
                   width: 1,
                   type: 'solid'
                 }
               },
               axisLabel: {
                 textStyle: {
                   color: "#3FDDFF",
                 },
               },
               show:false, // don't show the axis, axis tick marks and text on the axis
             },
             series: [
               {
                 data: y,
                 type: "line",
                 symbol: "none",
                 smooth: true,
                 itemStyle: {
                   normal: {
                     lineStyle: {
                       color: "#80DEFF",
                     },
                   },
                 },
                 areaStyle: {
                   color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
                     {
                       offset: 0,
                       color: "rgb(128, 222, 255, 1)",
                     },
                     {
                       offset: 1,
                       color: "rgb(128, 222, 255, 0.3)",
                     },
                   ]),
                 },
               },
             ],
           };
           this.registeredChart.setOption(options);
   
   ### Current Behavior
   
   When the mouse slides over the line chart, the error Uncaught TypeError: Cannot read properties of undefined (reading 'length') is reported, the error file Animator.js is reported, the function is interpolate1DArray, and the error is continuously accumulated.
   
   ### Expected Behavior
   
   Hope to find out the cause of the bug
   
   ### Environment
