Click events are given on the line chart and bar chart of Vue's echarts, respectively, and then jump to the corresponding page

The bar chart is rendered in

echart, but you need to give the corresponding click event on each column and then jump to the corresponding page

the solution on the CSDN searched on Baidu, but found that many posts are reprinted and copied from each other, but still do not meet the demand

drawLineChart () {

  let moduleRank = this.$echarts.init(document.getElementById("moduleRankLine"), null, {renderer: "svg"})
  let PPM = this.$echarts.init(document.getElementById("PPMLine"), null, {render: "svg"})
  let stackHash = this.$echarts.init(document.getElementById("stackHash"), null, {render: "svg"})
  let changeTendency = this.$echarts.init(document.getElementById("changeTendency"), null, {render: "svg"})
  moduleRank.setOption(moduleChartOption.rankOption, true)
  PPM.setOption(moduleChartOption.ppmOption, true)
  stackHash.setOption(moduleChartOption.stackHashOption, true)
  changeTendency.setOption(moduleChartOption.changeTendency, true)
  // ()
  changeTendency.on("click", function (param) {
   
    alert("" + param.data) // 
    this.openMessage() // 
  })
},




what result do you expect? What is the error message actually seen?
