详解如何使用vue实现可视化界面设计

var app = new Vue({
  el: '#app',
  data: {
    // 数据
  },
  methods: {
    // 方法
  },
  computed: {
    // 计算属性
  }
})

Vue.component('v-button', {
  props: ['text', 'size'],
  template: `
    <button :class="['btn', 'btn-' + size]">{{ text }}</button>
  `
})

npm install echarts --save

import echarts from 'echarts'
Vue.component('v-chart', {
  props: ['option'],
  mounted() {
    var chart = echarts.init(this.$el)
    chart.setOption(this.option)
  },
  template: `
    <div></div>
  `
})

<div id="app">
  <v-button text="click me" size="large"></v-button>
  <v-chart :option="barChartOption"></v-chart>
</div>

.btn {
  border-radius: 4px;
  border: none;
  cursor: pointer;
  font-size: 14px;
  padding: 8px 16px;
  background-color: #3085d6;
  color: #fff;
}
 
.btn:hover {
  background-color: #2573b5;
}
 
.btn-large {
  font-size: 18px;
  padding: 12px 24px;
}
 
.chart {
  width: 100%;
  height: 300px;
}

npm install echarts --save

import echarts from 'echarts'
 
Vue.component('v-chart', {
  props: ['option'],
  mounted() {
    var chart = echarts.init(this.$el)
    chart.setOption(this.option)
  },
  template: `
    <div class="chart"></div>
  `
})

var app = new Vue({
  el: '#app',
  data() {
    return {
      data: [], // 数据
      option: {} // Echarts选项
    }
  },
  methods: {
    fetchData() {
      // 从服务器加载数据
      axios.get('/api/data').then(res => {
        this.data = res.data
        this.updateChart()
      })
    },
    updateChart() {
      // 更新图表选项
      this.option = {
        xAxis: {
          type: 'category',
          data: this.data.map(item => item.time)
        },
        yAxis: {
          type: 'value'
        },
        series: [{
          data: this.data.map(item => item.value),
          type: 'line'
        }]
      }
    }
  },
  mounted() {
    // 初始化
    this.fetchData()
  }
})

<div id="app">
  <v-chart :option="option"></v-chart>
</div>
