在Nuxt中使用 Highcharts

npm进行highchars的导入，导入完成后就可以进行highchars的可视化组件开发了

npm install highcharts --save

1、components目录下新建一个chart.vue组件

<template>
  <div>
    <div v-if="hasNoData()">
      <p >{{ emptyText }}</p>
    </div>
    <div :id="id"  v-else></div>
  </div>
</template>

<script>
  import highcharts from 'highcharts';

  export default {
    props: {
      id: {
        type: String
      },
      config: {
        data: {
          required: true,
          type: Array
        },
        colors: {
          type: Array
        },
        option: {
          type: Object
        }
      },
      emptyText: {
        default: '暂无数据'
      }
    },
    data() {
      return {
        option: {
          chart: {
            type: 'column'
          },
          credits: {
            enabled: false
          },
          title: {
            text: null
          },
          xAxis: {
            type: 'category',
            tickWidth: 0
          },
          yAxis: {
            visible: false
          },
          legend: {
            enabled: false
          },
          ...this.config.option,
          plotOptions: {
            column: {
              colorByPoint: true,
              colors: this.config.colors,
              dataLabels: {
                enabled: true
              }
            }
          },
          series: [{
            data: this.config.data
          }]
        }
      };
    },
    methods: {
      hasNoData() {
        if (this.config.data) {
          return this.config.data.length > 0;
        }
        return true;
      }
    },
    beforeDestroy() {
      if (this.chart) {
        this.chart.destroy();
      }
    },
    created() {
    },
    mounted() {
      if (!this.hasNoData()) {
        this.chart = highcharts.chart(this.id, this.option);
      }
    }
  };
</script>

2、chart组件建好后，开始创建chart-options目录，里面创建一个options.js用来存放模拟的chart数据

module.exports = {
  bar: {
    colors: ['#a7d7f6', '#7ec2ef', '#ffad57', '#f29260', '#f93d3b'],
          data: [
            ['1号', 10],
            ['2号', 20],
            ['3号', 30],
            ['4号', 40],
            ['5号', 50]
          ],
          option: {
            tooltip: {
              formatter: function () {
                return `<span style="color:${this.color}">\u25CF</span> `;
              }
            }
          }
  }
}

3、引用chart组件

<template>
  <div id="app">
    <x-chart :id="id" :config="option" empty-text="暂无数据"></x-chart>
  </div>
</template>

<script>
// 导入chart组件
import XChart from 'components/chart.vue'
// 导入chart组件模拟数据
import options from './chart-options/options'
export default {
  name: 'app',
  data() {
    let option = options.bar
    return {
      id: 'test',
      option: option
    }
  },
  components: {
    XChart
  }
}
</script>

<style>
#test {
  width: 400px;
  height: 400px;
  margin: 40px auto;
}
</style>

如果是Nuxt使用Highcharts的话，记得在nuxt.config..js里的build里vendor里写入highcharts以减少应用 bundle 的体积

嗯，就酱~~
