甘特图

手动封装简版甘特图，纯展示功能，无其他操作

前言

开始的思路是使用echarts 瀑布图来体现，但是试验后发现，头部时间功能不满足，然未找到其他组件，于是手动封装一个，比较简陋，凑乎看。

</style>

使用

import GanttChart from '@/components/GanttChart.vue';

<GanttChart style="width:50%;height:30%; margin-top: 1.1%;" :chartData="chartData" height="16.3%"/>


import { ref } from 'vue';
let chartData = ref([
    [1.2,16.4],
    [5.5,10.8],
    [1,6.2],
    [5.2,9],
    [8.3,10.8],
])

总结

简单使用，至于数据需要处理后传入
