vue可视化开发,要求echarts 最多显示5条数据，超过5条数据定时切换显示。

数据切换代码

<script>
import top from './top/index'
import bottom from './bottom/index'
import {qualityInfo} from "@/api/api/accountCockpit";
import _ from 'lodash'
import {switchTime} from "@/api/ipConfig";
export default {
  name: "index",
  components: {top, bottom},
  props: {
    id: {
      type: String,
      default() {
        return '';
      }
    }
  },
  data() {
    return {
      list: [],
      active: 0,
      time: null
    }
  },
  watch: {},
  mounted() {
    this.getdata()
  },
  methods: {
    getactive() {
      if (this.active < this.list.length - 1) {
        this.active = this.active + 1
      } else {
        this.active = 0
      }
    },
    getswich() {
      clearInterval(this.time);
      let that = this;
      this.time = window.setInterval(() => {
        setTimeout(() => {
          that.getactive();
        }, 0)
      }, switchTime)
    },
    getdata() {
      var that = this
      qualityInfo().then((res) => {
        if (res.code == 200) {
          // that.list = res.data
          that.list = _.chunk(res.data, 5)
          this.getswich()
        }
      })
    },
  }
}
</script>

echarts 代码

    },
