vue使用html实现的一个项目进度图
比如一个项目，可能对应多个不同的时间阶段，需要单独显示。如下图。那么echart和一些其他进度组件，实现起来就比较麻烦，甚至echart无法实现这么好的效果。于是就自己写了一个。
需求是：一个项目需要显示多个阶段，并且每个阶段都要一样的渐变色，并且按照日期显示在准确的比例位置
效果图：
对比echart实现的效果
这个echart的原理是用坐标，将月份视为x坐标，那么比如mar有数据，jun有数据，那么就会出现这么一段，但是他无法实现精准的显示，比如我一个时间是3月5日，他不能按比例显示在正确的位置
再对比另一个echart效果
这个echart的原理是先显示带颜色的部分，然后在用一个和echart背景色相同的，长度为从0到这个带颜色部分的起点位置的bar盖住带颜色的bar就形成了这个效果，那么可见。渐变色达不到效果，圆角达不到效果，而且要实现多个，这个数据结构会很复杂。
综上还是决定自己用html实现一个，设计一个算法，显示再正确的比例位置
再看一下效果图

数据由表头和内容构成，如图：
1、表头是需要过滤的，比如23-26年之间都没有数据，那么就这之间的数据就全部不显示，只显示有数据的部分。
2、但是为了避免头部和尾部显示不全，又在已有表头数据的基础上，分别增加了一个节点。
3、为了便于区分，给每个这一年第一次出现的月份增加了一个年份的标记
