Echarts笔记

1.显示轴线

xAxis: {
  axisLine: { // 显示轴线
    show: true,
    onZero: false,
    lineStyle: {
      color: '#ffffff'
    }
  },
},

2.点击legend

legendClick(myChart, legendData)
option && myChart.setOption(option, true)

    legendClick(chart, legendData) {
      chart.off('legendselectchanged')
      // 定义当前点击的标签
      let legendWai = ''
      chart.on('legendselectchanged', function(obj) {
        legendWai = obj.name
        for (let i = 0; i < legendData.length; i++) {
          // 显示当前legend 关闭非当前legent
          if (legendWai == legendData[i]) {
            chart.dispatchAction({
              type: 'legendSelect',
              name: legendData[i]
            })
          } else {
            chart.dispatchAction({
              type: 'legendUnSelect',
              name: legendData[i]
            })
          }
        }
      })
    }
