使用echarts生成河道断面图

 let xAxisData = ["1", "2", "3", "4", "5", "6", "7", "8"];

    
 let yAxisData1 = [333, 333, 150, 113, 120, 100, 110, 333];
    
 let yAxisData2 = [233, 233, 233, 233, 233, 233, 233, 233];
    
  
    
 option = {
    
     "backgroundColor": "#fff",
    
     "tooltip": {
    
     "trigger": "axis"
    
     },
    
     "legend": {
    
     "data": ["1",'2'],
    
     "top": "10%"
    
     },
    
     "toolbox": {
    
     "show": false,
    
     "feature": {
    
         "dataZoom": {}
