uniapp,app端使用echarts不兼容，可以使用iframe来使用echarts

可以新建文件夹 echarts，里面放echart.min.js文件,echarts.html文件生成echarts图，之所以用iframe不用webview，是因为webview容易出问题，最明显问题是层级问题。

  
  
  
  
  
  K线图


    


  window.onload = function () {
				 // 解析URL参数
				const urlParams = new URLSearchParams(window.location.search);
      	const param1 = urlParams.get('param1');
				const data = JSON.parse(param1)
				console.log('K线图数据',data)
  // 基于准备好的dom，初始化echarts实例
  var myChart = echarts.init(document.getElementById('chart'), 'dark');
  let dates=[],min,max
  min = data[0].low
  max = data[data.length-1].high
  console.log('min',min,',max',max)
  function genData (){
      // let basePrice = 5000
      let dataList = []
      for (let i = 0; i 
                    收盘: ${params[0].data[2]}

                    最高: ${params[0].data[3]}

                    最低: ${params[0].data[4]}

                    时间: ${params[0].axisValue}
            `;
            return result;
          // return datas[0].name + '
' + datas[0].data[1] ; // 由于可能有多个series，因 此  params[0].name和.data表示第一个series的该坐标点 xAxis值和yAxis值 
        } 
        },
      xAxis: {
        type: 'category',
        data: dates,
        axisLabel: { //文字
          color:'#888',
          formatter: function (value) {
            return echarts.format.formatTime('MM-dd', value);
          }
        },
        axisLine: {  // 线
          lineStyle: { color: '#888888' },
        },  
      },
      yAxis: { //文字
        min:min,
        // max:max+0.1,
        axisLabel: {
          color:'#888',
            formatter: function (value) {
              return value.toFixed(4);
            }
          },
      },
      grid: {
        top: 10,
        left:60,
        // right:0,
        bottom:30,
      },
      series: [
        {
          type: 'candlestick',
          data: chartData,
          itemStyle: {
            color: '#3EC36CFF',
            color0: '#3EC36CFF',
            borderColor: '#3EC36CFF',
            borderColor0: '#3EC36CFF'
          }
        }
      ],
      dataZoom: [
        { type:"inside"} //详细配置可见echarts官网 
      //   { // 这个dataZoom组件，默认控制x轴。
      //   type: 'slider', // 这个 dataZoom 组件是 slider 型 dataZoom 组件
      //   start: 0,      // 左边在 0% 的位置。
      //   end: 100       // 右边在 100% 的位置。
      //  }
      ]
    };
    // 使用刚指定的配置项和数据显示图表。
    myChart.setOption(option);
    myChart.resize()
  }

调用，注意：inviteUrl是echarts.html服务器路径，this.postMess是需要传递的数据

// js调用地址跟数据传递
this.webViewSrc = inviteUrl+'/echarts/klinecharts.html?param1='+this.postMess

附上echarts.min.js
