本文主要是介绍vue 实现项目进度甘特图，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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"@scrollLeft="scrollLeftA"customGenerateBlocks:datas="ganttData"><templatev-slot:block="{data,getPositonOffset,getWidthAbout2Times,isInRenderingTimeRange,startTimeOfRenderArea,endTimeOfRenderArea,isAcrossRenderingTimeRange}"><divclass="gantt-block-item"v-for="(item, index) in data.gtArray"v-if="isInRenderingTimeRange(item.start) ||isInRenderingTimeRange(item.end) ||isAcrossRenderingTimeRange(item.start, item.end)":key="item.id":style="{left: getPositonOffset(item.start) + 'px',width: getWidthAbout2Times(item.start, item.end) + 'px',height: judgeTime(data.gtArray) ?
