项目需求：
实现以1天、7天、30天为周期（周期根据筛选条件选择），展示每个项目不同里程碑任务进度。
项目在Vue-Gantt-chart: 使用Vue做数据控制的Gantt图表基础上进行了改造。
有需要的小伙伴也可以直接引入插件，自己修改。
我是直接把甘特图封装成了组件，结构如下图：
首先，安装插件
npm install v-gantt-chart
引入插件（我是全局引入的）
import vGanttChart from 'v-gantt-chart';
Vue.use(vGanttChart);代码如下：
index.js
<template>
<div class="container">
<v-gantt-chart
:startTime="times[0]"
:endTime="times[1]"
:cellWidth="cellWidth"
:cellHeight="cellHeight"
:timeLines="timeLines"
:titleHeight="titleHeight"
:scale="Number(1440 * scale)"
:titleWidth="titleWidth"
showCurrentTime
:hideHeader="hideHeader"
:dataKey="dataKey"
:arrayKeys="arrayKeys"
:scrollToTime="scrollToTime"
:scrollToPostion="positionA"

<div

v-for="(item, index) in data.gtArray"

页面中使用

:scaleData="scaleData"
:scrollToTime="scrollToTime"
@nodeEventClick="nodeEventClick"
@panelDbClick="panelDbClick"
></ganttChart>
</div>import moment from 'moment';
import ganttChart from './components/ganttChart/index.vue';
export default {
components: { ganttChart },
data(){
return{
ganttArr: [],
scaleData: 10080,
scrollToTime: moment().subtract(4, 'days').format('YYYY-MM-DD'),
}
},
methods: {
// 点击甘特图node节点
nodeEventClick(item) {
// 执行自己的逻辑
},
// 双击甘特图左侧标题
panelDbClick(item) {
//执行自己的逻辑
}
}
}以上就是实现甘特图的全部过程，欢迎大佬们指教。
