   ```javascript
   let options = this.myChart.getOption()
   let keyName = 'keyName'
   /////////////////////////可以正常更改Y轴颜色、标签
   let newYAxis = options.yAxis.map((item, index) =>{
        if(item.name === keyName){
                return item
        }else{
                if(index > posInArr){
                        item.nameTextStyle.color = [options.color[index - 1]]
                        item.axisLabel.color = [options.color[index - 1]]
                        item.axisLine.lineStyle.color = [options.color[index - 
1]]
                        item.offset = (index - 1)*(-15)
                        item.position = (index -1) % 2 > 0 ? 'right' : 'left'
                }

        }

                newYAxis.splice(index,1)
        }
   })
   
   /////////////////////////不能正常更改线条及visualMap颜色
   let newVisualMap = options.visualMap.map((item, index) =>{
        if(item.name === keyName){
                return item
        }else{
                if(index > posInArr){
                        item.seriesIndex = item.seriesIndex -1
                        item.inRange.color = [options.color[index - 1]]
                }
                return item
        }
   })

        }
   })
   
   
   options.visualMap = newVisualMap
   myChart.setOption(options, {notMerge:true})
